MGI Phenotype FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] The protein encoded by this gene represents the alpha subunit of the Go heterotrimeric G-protein signal-transducing complex. Defects in this gene are a cause of early-onset epileptic encephalopathy. Two transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Aug 2015]
PHENOTYPE: Mice lacking both isoforms exhibit reduced survival, sterility, low body weight, hyperalgesia, tremors, turning behavior, impaired locomotion, altered channel response and improved glucose tolerance. Isoform-specific deletion may lead to increased insulin release and abnormal eye electrophysiology. [provided by MGI curators]
