Map1b Gene Summary [Rat]
Enables actin binding activity; microtubule binding activity; and phospholipid binding activity. Involved in several processes, including nervous system development; positive regulation of cell differentiation; and regulation of microtubule polymerization or depolymerization. Located in several cellular components, including axon; dendrite; and perikaryon. Part of microtubule associated complex. Biomarker of hypothyroidism. Human ortholog(s) of this gene implicated in autosomal dominant nonsyndromic deafness 83 and periventricular nodular heterotopia. Orthologous to human MAP1B (microtubule associated protein 1B).

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 Map1b often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
