Tiam1 Gene Summary [Mouse]
Enables several functions, including guanyl-nucleotide exchange factor activity; microtubule binding activity; and signaling receptor binding activity. Involved in several processes, including activation of GTPase activity; brain-derived neurotrophic factor receptor signaling pathway; and regulation of dopaminergic neuron differentiation. Acts upstream of or within ephrin receptor signaling pathway; positive regulation of axonogenesis; and small GTPase-mediated signal transduction. Located in kinocilium; pericentriolar material; and plasma membrane. Is expressed in several structures, including central nervous system; genitourinary system; sensory organ; skin; and tooth. 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 mouse 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.
