Predicted to enable signaling receptor complex adaptor activity. Involved in several processes, including cellular response to organonitrogen compound; regulation of egg-laying behavior; and regulation of pharyngeal pumping. Located in neuronal cell body. Expressed in body wall musculature; neurons; pharyngeal muscle cell; and vulval muscle. Human ortholog(s) of this gene implicated in intellectual developmental disorder with cardiac arrhythmia. Is an ortholog of human GNB5 (G protein subunit beta 5).
This gene belongs to the guanine-binding protein (GBP) family, which includes interferon-induced proteins that can bind to guanine nucleotides (GMP, GDP and GTP). The encoded protein is a GTPase which hydrolyzes GTP, predominantly to GDP. The protein may play a role as a marker of squamous cell carcinomas. [provided by RefSeq, Jul 2013]
This gene encodes a protein that is highly similar to the rat Grp78-binding protein (GBP). Alternatively spliced transcript variants encoding different isoforms have been described. [provided by RefSeq, Jul 2008]
