Structural highlights
Disease
HOOK1_MOUSE Note=Defects in Hook1 are the cause of the azh (abnormal spermatozoon head shape) mutant phenotype, which induces spermatozoa with highly abnormal head morphology that differs drastically from the compact and hook-shaped head of the normal sperm, leading to a strong decrease of fertility.
Function
HOOK1_MOUSE 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) (By similarity). Required for spermatid differentiation. Probably involved in the positioning of the microtubules of the manchette and the flagellum in relation to the membrane skeleton.
