Summary: Predicted to enable protein dimerization activity. Predicted to contribute to guanyl-nucleotide exchange factor activity. Acts upstream of or within with a negative effect on gene expression. Acts 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. Used to study Hermansky-Pudlak syndrome 1 and platelet storage pool deficiency. 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).

HPS1 Regulates the Maturation of Large Dense Core Vesicles and Lysozyme Secretion in Paneth Cells.
Title: HPS1 Regulates the Maturation of Large Dense Core Vesicles and Lysozyme Secretion in Paneth Cells.
This study analyzed the plasma lipid profiles of three HPS mutant mice, pa (Hps9 (-/-)), ru (Hps6 (-/-)), ep (Hps1 (-/-)), and wild-type (WT) mice. The findings may provide clues to explain why different HPS mutant mice exhibit distinct anti-atherosclerotic or atherogenic effects after being exposed to high-cholesterol diets.
Title: Plasma lipidomic profiling in murine mutants of Hermansky-Pudlak syndrome reveals differential changes in pro- and anti-atherosclerotic lipids.
Together, the results indicate that the Hps1 and Ap3b1 genes play distinct roles in male reproductive system development and spermatogenesis in mice
Title: Different functions of biogenesis of lysosomal organelles complex 3 subunit 1 (Hps1) and adaptor-related protein complex 3, beta 1 subunit (Ap3b1) genes on spermatogenesis and male fertility.
This may account for the tight correlation between Hps1 with Ptbp1 expression levels observed across mammalian tissues.
Title: Regulation of mRNA abundance by polypyrimidine tract-binding protein-controlled alternate 5' splice site choice.
Our study indicates that Ap3b1 gene play distinct roles in melanin production and tyrosinase distribution compared with Hps1 gene.
Title: The Ap3b1 gene regulates the ocular melanosome biogenesis and tyrosinase distribution differently from the Hps1 gene.
The mouse genes for HPS, pale ear and pearl, orthologous to the human HPS1 and HPS2 (ADTB3A) genes, copperate in production of platelet dense granules, melanosomes, and lysosomes.
Title: The Hermansky-Pudlak syndrome 1 (HPS1) and HPS2 genes independently contribute to the production and function of platelet dense granules, melanosomes, and lysosomes.
The coat-color phenotype of young homozygous double-mutant mice deficient in subunits of BLOC-3 (HPS1) and BLOC-1 (pallidin) was indistinguishable from that of BLOC-1 single mutants.
Title: Biogenesis of lysosome-related organelles complex 3 (BLOC-3): a complex containing the Hermansky-Pudlak syndrome (HPS) proteins HPS1 and HPS4.
Defects in the ep protein not only affect melanosome biogenesis, but also play a developmental role in determining interfollicular epidermal and dermal melanocyte function.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
