PRSS3 pseudogene 4 (PRSS3P4)

PRSS3P4 is a **pseudogene** related to the PRSS3 gene family but does not encode a functional protein or exert known biological or pharmacological effects. Pseudogenes arise when a gene becomes inactivated by mutation or loss of regulatory elements, retaining sequence similarity to the functional gene but lacking its enzymatic or biological activity. The functional PRSS3 gene encodes a digestive serine protease (trypsin-4/mesotrypsin) involved in proteolysis in the pancreas and brain, but there is no evidence that PRSS3P4 itself is expressed, translated, or plays any direct role in physiology or disease[3][4][5].\n\n**Key distinctions:**\n- PRSS3P4 should not be confused with **PRSS3** (mesotrypsin/trypsin-4), which is a serine protease with disease associations[1][2][3][4][5].\n- As a pseudogene, PRSS3P4 does not have *known drug interactions*, *measurable activity*, or *utility as a biomarker or target*.\n\nIf you are seeking information on the functional serine protease, refer to protease, serine 3 (PRSS3), not the pseudogene PRSS3P4.
