Summary: Enables several functions, including beta-tubulin binding activity; glutathione transmembrane transporter activity; and scaffold protein binding activity. Involved in several processes, including cellular response to amyloid-beta; glutamate secretion; and positive regulation of cold-induced thermogenesis. Acts upstream of or within several processes, including cell communication by chemical coupling; circulatory system development; and regulation of gene expression. Located in several cellular components, including fascia adherens; gap junction; and lateral plasma membrane. Is expressed in several structures, including alimentary system; embryo ectoderm; genitourinary system; heart and pericardium; and sensory organ. Used to study oculodentodigital dysplasia. Human ortholog(s) of this gene implicated in several diseases, including bone disease (multiple); erythrokeratodermia variabilis (multiple); hypoplastic left heart syndrome; oculodentodigital dysplasia; and palmoplantar keratoderma and congenital alopecia 1. Orthologous to human GJA1 (gap junction protein alpha 1). [provided by Alliance of Genome Resources, Dec 2024]

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
