Trak2 Gene Summary [Rat]
Enables several functions, including GABA receptor binding activity; TPR domain binding activity; and kinesin binding activity. Involved in several processes, including dendrite morphogenesis; dendritic transport of mitochondrion; and negative regulation of axonogenesis. Located in several cellular components, including axonal growth cone; early endosome; and neuronal cell body. Orthologous to human TRAK2 (trafficking kinesin protein 2).

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 Trak2 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
