Automated description from the Alliance of Genome Resources (Release 7.0.0)
Enables G protein activity. Involved in modification of postsynaptic structure. Acts upstream of or within several processes, including negative regulation of regulated secretory pathway; positive regulation of ERK1 and ERK2 cascade; and small GTPase-mediated signal transduction. Is active in glutamatergic synapse. Is expressed in brain and eye. Human ortholog(s) of this gene implicated in thrombocytopenia. Orthologous to several human genes including RAP1B (RAP1B, member of RAS oncogene family).
