    Summary
    Predicted to enable gap junction channel activity. Predicted to be involved in cell-cell signaling and gap junction-mediated intercellular transport. Predicted to act upstream of or within olfactory behavior and sensory perception of smell. Predicted to be located in cell junction; nuclear lumen; and plasma membrane. Predicted to be part of connexin complex. Human ortholog(s) of this gene implicated in erythrokeratodermia variabilis and erythrokeratodermia variabilis et progressiva 2. Orthologous to human GJB4 (gap junction protein beta 4). [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.
