Summaries for KPTN Gene

Entrez Gene Summary for KPTN Gene

  • This gene encodes a filamentous-actin-associated protein, which is involved in actin dynamics and plays an important role in neuromorphogenesis. Mutations in this gene result in recessive mental retardation-41. Alternatively spliced transcript variants have been found for this gene. [provided by RefSeq, Apr 2014]

GeneCards Summary for KPTN Gene

KPTN (Kaptin (Actin Binding Protein)) is a Protein Coding gene. Diseases associated with KPTN include Mental Retardation, Autosomal Recessive 41 and Macrocephaly-Developmental Delay Syndrome. GO annotations related to this gene include actin binding.

UniProtKB/Swiss-Prot for KPTN Gene

  • Necessary for normal neuromorphogenesis. May be involved in actin dynamics. May play a role in producing the sensory apparatus in hair cells. May play a role in actin rearrangements that accompany platelet activation and stereocilia formation.

  • Mental retardation, autosomal recessive 41 (MRT41) [MIM:615637]: A disorder characterized by significantly below average general intellectual functioning associated with impairments in adaptive behavior and manifested during the developmental period. MRT41 most consistent features are global developmental delay, macrocephaly with frontal bossing, high levels of anxiety, and some features suggestive of a pervasive developmental disorder. Less common features include fifth finger clinodactyly, recurrent pneumonia, and hepatosplenomegaly. {ECO:0000269 PubMed:24239382}. Note=The disease is caused by mutations affecting the gene represented in this entry.
