Hook2 Gene Summary [Rat]
Predicted to enable dynein light intermediate chain binding activity; identical protein binding activity; and microtubule binding activity. Predicted to be involved in several processes, including early endosome to late endosome transport; endosome to lysosome transport; and protein localization to perinuclear region of cytoplasm. Predicted to be located in cytosol and trans-Golgi network. Predicted to be part of FHF complex and HOPS complex. Predicted to be active in centrosome and cytoplasm. Orthologous to human HOOK2 (hook microtubule tethering protein 2). [provided by Alliance of Genome Resources, Jul 2025]

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 Hook2 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
