Protein attributes

Sequence length	1004 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is not processed.
Protein existence	Evidence at protein level.

General annotation (Comments)

Function	Involved in early stages of melanosome biogenesis and maturation By similarity.
Subcellular location	Cytoplasm By similarity.
Tissue specificity	Widely expressed. Higher levels of expression are observed in kidney, liver and placenta.
Involvement in disease	Defects in HPS3 are the cause of Hermansky-Pudlak syndrome type 3 (HPS3) [MIM:203300]. Hermansky-Pudlak syndrome (HPS) is a genetically heterogeneous, rare, 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. Ref.1 Ref.6
