Summary
HPS5 (HPS5 biogenesis of lysosomal organelles complex 2 subunit 2, HGNC:17022) is a protein-coding gene on chromosome 11p15.1, encoding BLOC-2 complex member HPS5 (Q9UPZ3). May regulate the synthesis and function of lysosomes and of highly specialized organelles, such as melanosomes and platelet dense granules.
This gene encodes a protein that may play a role in organelle biogenesis associated with melanosomes, platelet dense granules, and lysosomes. This protein interacts with Hermansky-Pudlak syndrome 6 protein and may interact with the cytoplasmic domain of integrin, alpha-3. Mutations in this gene are associated with Hermansky-Pudlak syndrome type 5. Multiple transcript variants encoding two distinct isoforms have been identified for this gene.

Literature-anchored findings (GeneRIF, showing 7)
- Component of BLOC-2. Results suggest a common biological basis underlying the pathogenesis of HPS-3, -5 and -6 disease. (PMID:15030569)
- LAMP-3 distribution was restricted to the perinuclear region in HPS-5 fibroblasts, instead of extending to the periphery (PMID:15296495)
- Tyrosinase and TYRP1 are mistrafficked, however, and fail to be efficiently delivered to melanosomes of HPS-5 melanocytes (PMID:17301833)
- Seven mutations (six previously unreported) were described in the HPS1, HPS4, and HPS5 genes among Hermansky-Pudlak Syndrome patients of Mexican, Uruguayan, Honduran, Cuban, Venezuelan, and Salvadoran ancestries. (PMID:21833017)
- We report a 92-year-old man with HPS 5 who, to our knowledge, is the oldest patient with HPS documented in the literature. (PMID:23607980)
- HPS5 mutation is associated with high hypopigmentation in Hermansky-Pudlak syndrome. (PMID:27593200)
- This case underscores the importance of recognizing the mild clinical phenotype of HPS-5 and utilization of both laboratory and molecular testing for diagnosis, prognostication, and surveillance for end organ damage in patients affected with HPS. (PMID:29090612)

Function. May regulate the synthesis and function of lysosomes and of highly specialized organelles, such as melanosomes and platelet dense granules. Regulates intracellular vesicular trafficking in fibroblasts. May be involved in the regulation of general functions of integrins.
Subunit / interactions. Component of the biogenesis of lysosome-related organelles complex-2 (or BLOC2) composed of HPS3, HPS5 and HPS6. Interacts with HPS6. Interacts with HPS3. May interact with all alpha-integrin chains that have an aromatic residue before the first lysine of the conserved KXGFFKR motif, including ITGA2, ITGA3, ITGA5 and ITGA6.
Subcellular location. Cytoplasm. Cytosol.
Tissue specificity. Widely expressed. Isoform 1:Highly expressed in lungs and testis. Isoform 2:Highly expressed in placenta, kidney, testis ovary, lung and thymus.
Disease relevance. Hermansky-Pudlak syndrome 5 (HPS5) [MIM:614074] A form of Hermansky-Pudlak syndrome, a genetically heterogeneous autosomal recessive disorder characterized by oculocutaneous albinism, bleeding due to platelet storage pool deficiency, and lysosomal storage defects. This syndrome results from defects of diverse cytoplasmic organelles including melanosomes, platelet dense granules and lysosomes. Ceroid storage in the lungs is associated with pulmonary fibrosis, a common cause of premature death in individuals with HPS. The disease is caused by variants affecting the gene represented in this entry.
Similarity. Belongs to the HPS5 family.
