Hps1 Gene Summary [Rat]
Predicted to enable protein dimerization activity. Predicted to contribute to guanyl-nucleotide exchange factor activity. Predicted to be involved in melanosome assembly. Predicted to act upstream of or within with a negative effect on gene expression. Predicted to act upstream of or within several processes, including intracellular zinc ion homeostasis; positive regulation of natural killer cell activation; and secretion of lysosomal enzymes. Predicted to be located in cytoplasmic vesicle. Predicted to be part of BLOC-3 complex. Human ortholog(s) of this gene implicated in Hermansky-Pudlak syndrome 1 and oculocutaneous albinism. Orthologous to human HPS1 (HPS1 biogenesis of lysosomal organelles complex 3 subunit 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 Hps1 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
