Plxnb2 Gene Summary [Mouse]
Enables semaphorin receptor activity. Involved in several processes, including nervous system development; regulation of neuron migration; and semaphorin-plexin signaling pathway. Acts upstream of or within positive regulation of axonogenesis. Located in plasma membrane. Is expressed in several structures, including alimentary system; brain; genitourinary system; respiratory system; and sensory organ. Orthologous to human PLXNB2 (plexin B2).

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 mouse Plxnb2 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
