This gene encodes a member of the gap junction protein family. The gap junction proteins are membrane-spanning proteins that assemble to form gap junction channels that facilitate the transfer of ions and small molecules between cells. According to sequence similarities at the nucleotide and amino acid levels, the gap junction proteins are divided into two categories, alpha and... See more...

Summaries for GJB1 Gene

Entrez Gene Summary for GJB1 Gene

  • This gene encodes a member of the gap junction protein family. The gap junction proteins are membrane-spanning proteins that assemble to form gap junction channels that facilitate the transfer of ions and small molecules between cells. According to sequence similarities at the nucleotide and amino acid levels, the gap junction proteins are divided into two categories, alpha and beta. Mutations in this gene cause X-linked Charcot-Marie-Tooth disease, an inherited peripheral neuropathy. Alternatively spliced transcript variants encoding the same protein have been found for this gene. [provided by RefSeq, Oct 2008]

GeneCards Summary for GJB1 Gene

GJB1 (Gap Junction Protein Beta 1) is a Protein Coding gene. Diseases associated with GJB1 include Charcot-Marie-Tooth Disease, X-Linked Dominant, 1 and X-Linked Charcot-Marie-Tooth Disease. Among its related pathways are Long-term potentiation and Myometrial Relaxation and Contraction Pathways. Gene Ontology (GO) annotations related to this gene include protein homodimerization activity. An important paralog of this gene is GJB6.

UniProtKB/Swiss-Prot Summary for GJB1 Gene

  • One 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.

Tocris Summary for GJB1 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).

  • Charcot-Marie-Tooth disease, X-linked dominant, 1 (CMTX1) [MIM:302800]: A form of Charcot-Marie-Tooth disease, a disorder of the peripheral nervous system, characterized by progressive weakness and atrophy, initially of the peroneal muscles and later of the distal muscles of the arms. Charcot-Marie-Tooth disease is classified in two main groups on the basis of electrophysiologic properties and histopathology: primary peripheral demyelinating neuropathies characterized by severely reduced motor nerve conduction velocities (NCVs) (less than 38m/s) and segmental demyelination and remyelination, and primary peripheral axonal neuropathies characterized by normal or mildly reduced NCVs and chronic axonal degeneration and regeneration on nerve biopsy. CMTX1 has both demyelinating and axonal features. Central nervous system involvement may occur. {ECO:0000269 PubMed:10071100, ECO:0000269 PubMed:10220155, ECO:0000269 PubMed:10234007, ECO:0000269 PubMed:10586284, ECO:0000269 PubMed:10732813, ECO:0000269 PubMed:10737979, ECO:0000269 PubMed:10873293, ECO:0000269 PubMed:10894999, ECO:0000269 PubMed:10923043, ECO:0000269 PubMed:10938190, ECO:0000269 PubMed:11030070, ECO:0000269 PubMed:11140841, ECO:0000269 PubMed:11180613, ECO:0000269 PubMed:11437164, ECO:0000269 PubMed:11438991, ECO:0000269 PubMed:11562788, ECO:0000269 PubMed:11571214, ECO:0000269 PubMed:11723288, ECO:0000269 PubMed:11835375, ECO:0000269 PubMed:11891346, ECO:0000269 PubMed:12185164, ECO:0000269 PubMed:12207932, ECO:0000269 PubMed:12325071, ECO:0000269 PubMed:12402337, ECO:0000269 PubMed:12477701, ECO:0000269 PubMed:12497641, ECO:0000269 PubMed:12536289, ECO:0000269 PubMed:12707076, ECO:0000269 PubMed:14627639, ECO:0000269 PubMed:15241803, ECO:0000269 PubMed:15468313, ECO:0000269 PubMed:15852376, ECO:0000269 PubMed:27234031, ECO:0000269 PubMed:7477983, ECO:0000269 PubMed:7833935, ECO:0000269 PubMed:8004109, ECO:0000269 PubMed:8162049, ECO:0000269 PubMed:8266101, ECO:0000269 PubMed:8628473, ECO:0000269 PubMed:8698335, ECO:0000269 PubMed:8733054, ECO:0000269 PubMed:8737658, ECO:0000269 PubMed:8807343, ECO:0000269 PubMed:8829637, ECO:0000269 PubMed:8889588, ECO:0000269 PubMed:8956046, ECO:0000269 PubMed:8990008, ECO:0000269 PubMed:9018031, ECO:0000269 PubMed:9099841, ECO:0000269 PubMed:9187667, ECO:0000269 PubMed:9272161, ECO:0000269 PubMed:9361298, ECO:0000269 PubMed:9452025, ECO:0000269 PubMed:9452099, ECO:0000269 PubMed:9469569, ECO:0000269 PubMed:9633821, ECO:0000269 PubMed:9818870, ECO:0000269 PubMed:9856562, ECO:0000269 Ref.12}.

There are both autosomal dominant and autosomal recessive forms of Dejerine-Sottas syndrome. {ECO:0000269 PubMed:15947997}. Note=The gene represented in this entry may act as a disease modifier.
