Sema4b Gene Summary [Mouse]
Predicted to enable chemorepellent activity; neuropilin binding activity; and semaphorin receptor binding activity. Predicted to be involved in several processes, including axon guidance; neural crest cell migration; and semaphorin-plexin signaling pathway. Located in plasma membrane and synapse. Is active in glutamatergic synapse and postsynaptic density membrane. Is expressed in several structures, including back musculature; central nervous system; peripheral nervous system ganglion; and retina. Orthologous to human SEMA4B (semaphorin 4B).

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 Sema4b often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
