The encoded protein is a component of gap junction channels and functions in a calcium and pH-dependent manner. Mutations in this gene have been associated with zonular pulverulent cataracts, nuclear progressive cataracts, and cataract-microcornea syndrome. [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| |Connexin CCC| |Connexin50| |gap junction-mediated intercellular transport| |intercellular transport| |gap junction channel activity| |connexin complex| |lens development in camera-type eye| |camera-type eye development| |protein homooligomerization| |eye development| |visual system development| |sensory system development| |protein complex oligomerization| |sensory organ development| |cell-cell signaling| |transmembrane transport| |integral component of plasma membrane| |protein-containing complex assembly| |protein-containing complex subunit organization| \\ === CRISPR Data === ^Screen^Score^ |[[:results:exp121|Golgicide-A 2μM R03 exp121]]|-1.87| |[[:results:exp106|UM131593 0.2μM R03 exp106]]|-1.82| |[[:results:exp131|L-74142 5μM R03 exp131]]|1.72| No correlation found to any other genes in chemogenomics.
