    Summary
    Predicted to enable gap junction channel activity involved in cell communication by electrical coupling. Involved in several processes, including negative regulation of G1/S transition of mitotic cell cycle; nervous system development; and positive regulation of calcium ion transmembrane transport. Located in several cellular components, including paranode region of axon; perikaryon; and proximal neuron projection. Biomarker of Parkinson's disease. Human ortholog(s) of this gene implicated in hereditary lymphedema IC; hereditary spastic paraplegia 44; hypomyelinating leukodystrophy 2; and lymphedema. Orthologous to human GJC2 (gap junction protein gamma 2). [provided by Alliance of Genome Resources, Apr 2022]

    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.
