Summaries for GJA1 Gene

Entrez Gene Summary for GJA1 Gene

  • This gene is a member of the connexin gene family. The encoded protein is a component of gap junctions, which are composed of arrays of intercellular channels that provide a route for the diffusion of low molecular weight materials from cell to cell. The encoded protein is the major protein of gap junctions in the heart that are thought to have a crucial role in the synchronized contraction of the heart and in embryonic development. A related intronless pseudogene has been mapped to chromosome 5. Mutations in this gene have been associated with oculodentodigital dysplasia, autosomal recessive craniometaphyseal dysplasia and heart malformations. [provided by RefSeq, May 2014]

GeneCards Summary for GJA1 Gene

GJA1 (Gap Junction Protein Alpha 1) is a Protein Coding gene. Diseases associated with GJA1 include Oculodentodigital Dysplasia and Syndactyly, Type Iii. Among its related pathways are N-cadherin signaling events and Gap junction trafficking. Gene Ontology (GO) annotations related to this gene include receptor binding and protein domain specific binding. An important paralog of this gene is GJA3.

UniProtKB/Swiss-Prot for GJA1 Gene

  • Gap junction protein that acts as a regulator of bladder capacity. A gap junction consists of a cluster of closely packed pairs of transmembrane channels, the connexons, through which materials of low MW diffuse from one cell to a neighboring cell. May play a critical role in the physiology of hearing by participating in the recycling of potassium to the cochlear endolymph. Negative regulator of bladder functional capacity: acts by enhancing intercellular electrical and chemical transmission, thus sensitizing bladder muscles to cholinergic neural stimuli and causing them to contract (By similarity). May play a role in cell growth inhibition through the regulation of NOV expression and localization. Plays an essential role in gap junction communication in the ventricles (By similarity).

Tocris Summary for GJA1 Gene

  • Gap channels (gap junctions) are specialized cell-cell contacts that provide direct intracellular communication. They allow passive diffusion of molecules up to 1 kDa, including nutrients, metabolites (glucose), ions (K+, Ca2+) and second messengers (IP3, cAMP).

Post-translational modifications for GJA1 Gene

  • Phosphorylated at Ser-368 by PRKCG; phosphorylation induces disassembly of gap junction plaques and inhibition of gap junction activity (By similarity). Phosphorylation at Ser-325, Ser-328 and Ser-330 by CK1 modulates gap junction assembly. Phosphorylation at Ser-368 by PRKCD triggers its internalization into small vesicles leading to proteasome-mediated degradation (By similarity).
  • S-nitrosylation at Cys-271 is enriched at the muscle endothelial gap junction in arteries, it augments channel permeability and may regulate of smooth muscle cell to endothelial cell communication.
  • Sumoylated with SUMO1, SUMO2 and SUMO3, which may regulate the level of functional Cx43 gap junctions at the plasma membrane. May be desumoylated by SENP1 or SENP2.
  • Ubiquitination at posLast=99 and posLast=303303

  • Atrioventricular septal defect 3 (AVSD3) [MIM:600309]: A congenital heart malformation characterized by a common atrioventricular junction coexisting with deficient atrioventricular septation. The complete form involves underdevelopment of the lower part of the atrial septum and the upper part of the ventricular septum; the valve itself is also shared. A less severe form, known as ostium primum atrial septal defect, is characterized by separate atrioventricular valvar orifices despite a common junction. {ECO:0000269 PubMed:11470490}. Note=The disease is caused by mutations affecting the gene represented in this entry.
  • Craniometaphyseal dysplasia, autosomal recessive (CMDR) [MIM:218400]: An osteochondrodysplasia characterized by hyperostosis and sclerosis of the craniofacial bones associated with abnormal modeling of the metaphyses. Sclerosis of the skull may lead to asymmetry of the mandible, as well as to cranial nerve compression, that may finally result in hearing loss and facial palsy. {ECO:0000269 PubMed:23951358}. Note=The disease is caused by mutations affecting the gene represented in this entry.
  • Erythrokeratodermia variabilis et progressiva 3 (EKVP3) [MIM:617525]: A form of erythrokeratodermia variabilis et progressiva, a genodermatosis characterized by the coexistence of two independent skin lesions: transient erythema and hyperkeratosis that is usually localized but occasionally occurs in its generalized form. Clinical presentation varies significantly within a family and from one family to another. Palmoplantar keratoderma is present in around 50% of cases. {ECO:0000269 PubMed:25398053}.

  • Hallermann-Streiff syndrome (HSS) [MIM:234100]: A disorder characterized by a typical skull shape (brachycephaly with frontal bossing), hypotrichosis, microphthalmia, cataracts, beaked nose, micrognathia, skin atrophy, dental anomalies and proportionate short stature. Mental retardation is present in a minority of cases. {ECO:0000269 PubMed:14974090}. Note=The disease is caused by mutations affecting the gene represented in this entry.
  • Hypoplastic left heart syndrome 1 (HLHS1) [MIM:241550]: A syndrome due to defective development of the aorta proximal to the entrance of the ductus arteriosus, and hypoplasia of the left ventricle and mitral valve. As a result of the abnormal circulation, the ductus arteriosus and foramen ovale are patent and the right atrium, right ventricle, and pulmonary artery are enlarged. {ECO:0000269 PubMed:11470490}. Note=The disease is caused by mutations affecting the gene represented in this entry.
  • Oculodentodigital dysplasia (ODDD) [MIM:164200]: A disease characterized by a typical facial appearance and variable involvement of the eyes, dentition, and fingers. Characteristic facial features include a narrow, pinched nose with hypoplastic alae nasi, prominent columella and thin anteverted nares together with a narrow nasal bridge, and prominent epicanthic folds giving the impression of hypertelorism. The teeth are usually small and carious. Typical eye findings include microphthalmia and microcornea. The characteristic digital malformation is complete syndactyly of the fourth and fifth fingers (syndactyly type III) but the third finger may be involved and associated camptodactyly is a common finding. Cardiac abnormalities are observed in rare instances. {ECO:0000269 PubMed:12457340, ECO:0000269 PubMed:14729836, ECO:0000269 PubMed:15108203, ECO:0000269 PubMed:15637728, ECO:0000269 PubMed:16219735, ECO:0000269 PubMed:16222672, ECO:0000269 PubMed:16378922, ECO:0000269 PubMed:16709485, ECO:0000269 PubMed:16813608, ECO:0000269 PubMed:16816024, ECO:0000269 PubMed:17509830, ECO:0000269 PubMed:18161618, ECO:0000269 PubMed:19338053, ECO:0000269 PubMed:21670345, ECO:0000269 PubMed:23550541, ECO:0000269 PubMed:24508941, ECO:0000269 PubMed:28258662}. Note=The disease is caused by mutations affecting the gene represented in this entry.
  • Oculodentodigital dysplasia, autosomal recessive (ODDD-AR) [MIM:257850]: A disease characterized by a typical facial appearance and variable involvement of the eyes, dentition, and fingers. Characteristic facial features include a narrow, pinched nose with hypoplastic alae nasi, prominent columella and thin anteverted nares together with a narrow nasal bridge, and prominent epicanthic folds giving the impression of hypertelorism. The teeth are usually small and carious. Typical eye findings include microphthalmia and microcornea. The characteristic digital malformation is complete syndactyly of the fourth and fifth fingers (syndactyly type III) but the third finger may be involved and associated camptodactyly is a common finding. Cardiac abnormalities are observed in rare instances. {ECO:0000269 PubMed:16816024}. Note=The disease is caused by mutations affecting the gene represented in this entry.
  • Palmoplantar keratoderma and congenital alopecia 1 (PPKCA1) [MIM:104100]: A rare autosomal dominant disorder characterized by severe hyperkeratosis of the palms and soles, and congenital hypotrichosis or alopecia. Dystrophic nail changes occur in some patients. {ECO:0000269 PubMed:25168385}. Note=The disease is caused by mutations affecting the gene represented in this entry.
  • Syndactyly 3 (SDTY3) [MIM:186100]: A form of syndactyly, a congenital anomaly of the hand or foot marked by persistence of the webbing between adjacent digits that are more or less completely attached. In SDTY3, there is usually complete and bilateral syndactyly between the fourth and fifth fingers. Usually it is soft tissue syndactyly but occasionally the distal phalanges are fused. The fifth finger is short with absent or rudimentary middle phalanx. The feet are not affected. {ECO:0000269 PubMed:14729836}. Note=The disease may be caused by mutations affecting the gene represented in this entry.
