Tiam1 Gene Summary [Rat]

Enables microtubule binding activity and receptor tyrosine kinase binding activity. Involved in several processes, including activation of GTPase activity; positive regulation of neurogenesis; and regulation of MAPK cascade. Located in several cellular components, including axon; dendritic spine; and ruffle membrane. Is active in glutamatergic synapse. Is extrinsic component of postsynaptic density membrane. Human ortholog(s) of this gene implicated in neurodevelopmental disorder with language delay and seizures. Orthologous to human TIAM1 (TIAM Rac1 associated GEF 1).

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 Tiam1 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
