Here’s a concise overview of recombinant human HPS3 protein:
The Hermansky-Pudlak syndrome 3 (HPS3) protein, encoded by the *HPS3* gene, is a critical component of the BLOC-2 (biogenesis of lysosome-related organelles complex-2) complex. This complex regulates intracellular trafficking and biogenesis of lysosome-related organelles, including melanosomes in pigment cells and dense granules in platelets. Mutations in *HPS3* cause Hermansky-Pudlak syndrome type 3. a rare autosomal recessive disorder characterized by oculocutaneous albinism, bleeding diathesis, and lysosomal dysfunction.
Recombinant human HPS3 protein is produced using expression systems (e.g., bacterial, mammalian, or insect cells) to generate purified protein for functional studies. Its production enables investigations into HPS3’s molecular interactions, its role in organelle formation, and pathological mechanisms underlying HPS3 deficiency. Researchers utilize this protein to study BLOC-2 assembly, vesicular transport pathways, and how HPS3 mutations disrupt melanin synthesis or platelet function. Additionally, it serves as a tool for developing diagnostic assays or evaluating potential therapies for HPS-related disorders. Understanding HPS3’s structure-function relationships may contribute to targeted interventions for associated clinical manifestations.
