Plxnb1 Gene Summary [Rat]
Predicted to enable GTPase activating protein binding activity and semaphorin receptor activity. Predicted to be involved in several processes, including negative regulation of osteoblast proliferation; nervous system development; and positive regulation of intracellular signal transduction. Is active in glutamatergic synapse and postsynaptic membrane. Orthologous to human PLXNB1 (plexin B1). [provided by Alliance of Genome Resources, Jul 2025]

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 Plxnb1 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
