这个基因编码鸟嘌呤核苷酸结合蛋白的一个γ亚单位这种蛋白质参与跨膜的信号传递机制。不同的亚单位形成异二聚体，然后与不同的信号分子相互作用[由RefSeq提供，2011年8月]
This gene encodes one of the gamma subunits of a guanine nucleotide-binding protein. Such proteins are involved in signaling mechanisms across membranes. Various subunits forms heterodimers which then interact with the different signal molecules. [provided by RefSeq, Aug 2011]
