Summary
Enables gap junction channel activity involved in AV node cell-bundle of His cell electrical coupling and monoatomic ion channel activity. Involved in AV node cell to bundle of His cell communication by electrical coupling and gap junction assembly. Acts upstream of or within several processes, including chemical synaptic transmission; circulatory system development; and visual perception. Located in gap junction. Part of connexin complex. Is expressed in several structures, including alimentary system; central nervous system; genitourinary system; heart; and integumental system. Orthologous to human GJC1 (gap junction protein gamma 1). [provided by Alliance of Genome Resources, Oct 2024]
Expression
Broad expression in CNS E11.5 (RPKM 15.7), limb E14.5 (RPKM 10.7) and 15 other tissues See more

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.
