Summary: Enables GTPase activator activity. Involved in several processes, including negative regulation of blood vessel remodeling; negative regulation of cellular extravasation; and regulation of vascular permeability. Acts upstream of or within several processes, including neuromuscular process controlling balance; regulation of vesicle-mediated transport; and response to lipopolysaccharide. Located in cytosol; glutamatergic synapse; and plasma membrane. Is active in Schaffer collateral - CA1 synapse. Is expressed in several structures, including alimentary system; mesothelium; metanephros; nervous system; and sensory organ. Orthologous to human ABR (ABR activator of RhoGEF and GTPase).

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.
