With a molecular mass of approximately 19 kDa EPPIN is mainly expressed in the male reproductive system particularly in the epididymis and on the surface of spermatozoa. This protein is recognized by several names including SPINLW1 which stands for Sperm protein with a Kunitz-type inhibitor domain. EPPIN interacts with the surface of sperm to regulate sperm motility and maturation.\u003cbr\u003e\nBiological function summary\u003cbr\u003e\nEPPIN influences sperm function by acting as part of a multi-protein complex essential for sperm motility and stability. It is known to bind with Semenogelin (SEMG) a major protein in semen impacting its hydrolytic and inhibitory action. Through this interaction EPPIN contributes to the liquefaction of semen and the regulation of sperm forward motility. It modulates calcium signaling in spermatozoa which is critical for the regulation of sperm activity post-ejaculation.\u003cbr\u003e\nPathways\u003cbr\u003e\nEPPIN has been implicated in pathways associated with reproductive processes. It plays a role in the regulation of the calcium signaling pathway which involves other proteins like CatSper which are essential for sperm capacitation and hyperactivation. EPPIN through its interaction with SEMG indirectly influences the proteolytic pathways that govern seminal fluid conversion from gel to liquid state necessary for the sperm to become fully motile.\u003cbr\u003e\nEPPIN has connections with male infertility and potential as a target for male contraception. Its interaction with SEMG has been studied in relation to infertility cases where sperm motility is compromised. Furthermore altered levels or functions of EPPIN could link to abnormal semen viscosity contributing to difficulties in natural conception. Researchers are exploring EPPIN as a target for non-hormonal male contraceptives leveraging its pivotal role in sperm functionality without affecting hormone levels.\u003c\/p\u003e","brand":"Abcam","offers":[{"title":"Default Title","offer_id":46848593494185,"sku":"ab185699","price":0.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/iright.com\/products\/abcam-ab185699","provider":"Iright","version":"1.0","type":"link"}
