Gene Information

human ... HOOK1(51361)

General description

The gene protein Hook homolog-1 (HOOK1) is mapped to human chromosome 1p32.1. It belongs to HOOK family of proteins. HOOK1 transcript is highly expressed in testis. The protein localizes to discrete punctate subcellular structures.

Anti-HOOK1 antibody produced in rabbit, a Prestige Antibody, is developed and validated by the Human Protein Atlas (HPA) project . Each antibody is tested by immunohistochemistry against hundreds of normal and disease tissues. These images can be viewed on the Human Protein Atlas (HPA) site by clicking on the Image Gallery link. The antibodies are also tested using immunofluorescence and western blotting. To view these protocols and other useful information about Prestige Antibodies and the HPA, visit

Biochem/physiol Actions

Protein Hook homolog-1 (HOOK1) has been shown to associate with microtubules. HOOK1 is important for cellular trafficking. It is involved in sorting of clathrin independent cargo proteins toward recycling in microtubule-dependent manner. HOOK1 in complex with FTS (Fused Toes) and FHIP (FTS and Hook Interacting Protein) interacts with components of the homotypic vesicular protein sorting (HOPS) complex. This interaction is important to promote vesicle trafficking. In the azh (abnormal spermatozoon head shape) mutant mouse, loss of HOOK1 function results in abnormal shape of sperm head and disturbs linking of the flagellum to the sperm head.

Features and Benefits

Prestige Antibodies® are highly characterized and extensively validated antibodies with the added benefit of all available characterization data for each target being accessible via the Human Protein Atlas portal linked just below the product name at the top of this page. The uniqueness and low cross-reactivity of the Prestige Antibodies® to other proteins are due to a thorough selection of antigen regions, affinity purification, and stringent selection. Prestige antigen controls are available for every corresponding Prestige Antibody and can be found in the linkage section.

Every Prestige Antibody is tested in the following ways:
  • IHC tissue array of 44 normal human tissues and 20 of the most common cancer type tissues.
  • Protein array of 364 human recombinant protein fragments.
