Recombinant Human Protein Hook homolog 1 (HOOK1)

Uniprot Id

Q9UJC3

Target Species

Human

Target Name

HOOK1

Target Full Name

Protein Hook homolog 1

Target Function

Component of the FTS/Hook/FHIP complex (FHF complex). The FHF complex may function to promote vesicle trafficking and/or fusion via the homotypic vesicular protein sorting complex (the HOPS complex). FHF complex promotes the distribution of AP-4 complex to the perinuclear area of the cell. Required for spermatid differentiation. Probably involved in the positioning of the microtubules of the manchette and the flagellum in relation to the membrane skeleton.

Target Subcellular Location

Cytoplasm. Cytoplasm, cytoskeleton.

Target Protein Families

Hook family

Target Background

This gene encodes a member of the hook family of coiled-coil proteins, which bind to microtubules and organelles through their N- and C-terminal domains, respectively. The encoded protein localizes to discrete punctuate subcellular structures, and interacts with several members of the Rab GTPase family involved in endocytosis. It is thought to link endocytic membrane trafficking to the microtubule cytoskeleton. Several alternatively spliced transcript variants have been identified, but the full-length nature of some of these variants has not been determined.
