======= GJB4 ======= == Gene Information == * **Official Symbol**: GJB4 * **Official Name**: gap junction protein beta 4 * **Aliases and Previous Symbols**: N/A * **Entrez ID**: [[https://www.ncbi.nlm.nih.gov/gene/?term=127534|127534]] * **UniProt**: [[https://www.uniprot.org/uniprot/Q9NTQ9|Q9NTQ9]] * **Interactions**: [[https://thebiogrid.org/search.php?search=GJB4&organism=9606|BioGRID]] * **PubMed articles**: [[https://www.ncbi.nlm.nih.gov/pubmed/?term=gene%20GJB4|Open PubMed]] * **OMIM**: [[https://omim.org/entry/605425|Open OMIM]] == Function Summary == * **Entrez Summary**: This gene encodes a transmembrane connexin protein that is a component of gap junctions. Mutations in this gene have been associated with erythrokeratodermia variabilis, progressive symmetric erythrokeratoderma and hearing impairment. [provided by RefSeq, Dec 2009]. * **UniProt Summary**: One gap junction consists of a cluster of closely packed pairs of transmembrane channels, the connexons, through which materials of low MW diffuse from one cell to a neighboring cell. |Connexin CCC| |Connexin| |gap junction-mediated intercellular transport| |intercellular transport| |gap junction channel activity| |olfactory behavior| |chemosensory behavior| |connexin complex| |sensory perception of smell| |sensory perception of chemical stimulus| |cell junction| |behavior| |nucleolus| |sensory perception| |cell-cell signaling| |transmembrane transport| |nervous system process| |integral component of plasma membrane| |system process| \\ === CRISPR Data === No hits were found.
