Abr Gene Summary [Rat]
Predicted to enable GTPase activator activity and guanyl-nucleotide exchange factor activity. Predicted to be involved in several processes, including activation of GTPase activity; negative regulation of blood vessel remodeling; and negative regulation of cellular extravasation. Predicted to act upstream of or within several processes, including negative regulation of macrophage migration; regulation of vesicle-mediated transport; and response to lipopolysaccharide. Is active in glutamatergic synapse and postsynaptic density, intracellular component. Orthologous to human ABR (ABR activator of RhoGEF and GTPase).

Protein Domains
A protein domain is a distinct structural or functional region within a protein that can evolve, function, and exist independently of the rest of the protein chain. These domains in rat Abr often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
