Hermansky–Pudlak syndrome 4 protein is a protein that in humans is encoded by the HPS4 gene.{{cite journal |vauthors=Suzuki T, Li W, Zhang Q, Karim A, Novak EK, Sviderskaya EV, Hill SP, Bennett DC, Levin AV, Nieuwenhuis HK, Fong CT, Castellan C, Miterski B, Swank RT, Spritz RA | title = Hermansky–Pudlak syndrome is caused by mutations in HPS4, the human homolog of the mouse light-ear gene | journal = Nat Genet | volume = 30 | issue = 3 | pages = 321–4 |date=Mar 2002 | pmid = 11836498 | doi = 10.1038/ng835 | s2cid = 2470873 }}{{cite journal |vauthors=Chiang PW, Oiso N, Gautam R, Suzuki T, Swank RT, Spritz RA | title = The Hermansky–Pudlak syndrome 1 (HPS1) and HPS4 proteins are components of two complexes, BLOC-3 and BLOC-4, involved in the biogenesis of lysosome-related organelles | journal = J Biol Chem | volume = 278 | issue = 22 | pages = 20332–7 |date=May 2003 | pmid = 12663659 | doi = 10.1074/jbc.M300090200 | doi-access = free }}{{cite web | title = Entrez Gene: HPS4 Hermansky–Pudlak syndrome 4| url = https://www.ncbi.nlm.nih.gov/sites/entrez?Db=gene&Cmd=ShowDetailView&TermToSearch=89781}}
Hermansky–Pudlak syndrome is a disorder of organelle biogenesis in which oculocutaneous albinism, bleeding, and pulmonary fibrosis result from defects of melanosomes, platelet dense granules, and lysosomes. Mutations in this gene as well as several others can cause this syndrome. The protein encoded by this gene appears to be important in organelle biogenesis and is similar to the mouse 'light ear' protein. Five transcript variants encoding different isoforms have been found for this gene. In addition, transcript variants utilizing alternative polyadenylation signals exist.
In melanocytic cells HPS4 gene expression may be regulated by MITF.{{cite journal |vauthors=Hoek KS, Schlegel NC, Eichhoff OM, etal | title = Novel MITF targets identified using a two-step DNA microarray strategy | journal = Pigment Cell Melanoma Res. | volume = 21 | issue = 6 | pages = 665–76 | year = 2008 | pmid = 19067971 | doi = 10.1111/j.1755-148X.2008.00505.x | doi-access = free }}
