FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] This gene encodes a member of the connexin protein family. Connexins are gap junction proteins which are arranged in groups of 6 around a central pore to form a connexon, a component of the gap junction intercellular channel. The channels formed by this protein allow cationic molecule exchange between human beta cells and may function in the regulation of insulin secretion. [provided by RefSeq, Oct 2012]
PHENOTYPE: Nullizygous mutations can cause loss of electrical synapses, impaired synchronous activity of inhibitory networks, altered spike synchrony in OB glomeruli, absent coupling of alpha-ganglion cells in retina, and abnormal cued conditioning, nerve fiber andsingle cell responses, and insulin secretion.
