    Summary
    Enables gap junction hemi-channel activity. Acts upstream of or within several processes, including cardiac muscle tissue development; cell communication by electrical coupling; and post-embryonic eye morphogenesis. Predicted to be located in plasma membrane. Predicted to be part of connexin complex. Is expressed in several structures, including kidney; liver; pericardial region; retina; and spinal cord. Human ortholog(s) of this gene implicated in cataract 14 multiple types. Orthologous to human GJA3 (gap junction protein alpha 3). [provided by Alliance of Genome Resources, Oct 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.
