Gene: GJA1 (gap junction protein alpha 1) Homo sapiens
Symbol: GJA1
Name: gap junction protein alpha 1
Description: Exhibits several functions, including alpha-tubulin binding activity; beta-catenin binding activity; and gap junction channel activity. Involved in several processes, including establishment of mitotic spindle orientation; negative regulation of gonadotropin secretion; and negative regulation of trophoblast cell migration. Localizes to several cellular components, including gap junction; intercalated disc; and tight junction. Implicated in congenital heart disease (multiple); erythrokeratodermia variabilis (multiple); oculodentodigital dysplasia; palmoplantar keratoderma and congenital alopecia 1; and palmoplantar keratosis. Biomarker of Huntington's disease; atrial fibrillation; cardiomyopathy (multiple); and tetralogy of Fallot.
Type: protein-coding
RefSeq Status: REVIEWED
