Summary: Predicted to enable several functions, including GTPase regulator activity; protein homodimerization activity; and small GTPase binding activity. Involved in regulation of postsynaptic membrane neurotransmitter receptor levels. Acts upstream of or within several processes, including behavioral fear response; glutamatergic synaptic transmission; and neuromuscular junction development. Located in several cellular components, including centrosome; lamellipodium; and ruffle. Is active in glutamatergic synapse and postsynaptic density. Is expressed in several structures, including central nervous system; genitourinary system; hemolymphoid system; liver; and retina. Human ortholog(s) of this gene implicated in amyotrophic lateral sclerosis and amyotrophic lateral sclerosis type 2. Orthologous to human ALS2 (alsin Rho guanine nucleotide exchange factor ALS2).

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
