Hook1 Gene Summary [Rat]
Predicted to enable cytoskeletal protein binding activity; dynein light intermediate chain binding activity; and protein homodimerization 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 act upstream of or within Golgi organization and manchette assembly. Predicted to be located in microtubule cytoskeleton. Predicted to be part of FHF complex and HOPS complex. Predicted to be active in centrosome and cytoplasm. Orthologous to human HOOK1 (hook microtubule tethering protein 1). [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 Hook1 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
