DESCRIPTION

Also known as HTRA3_HUMAN, HTRA3, PRSP. Serine protease that cleaves beta-casein/CSN2 as well as several extracellular matrix (ECM) proteoglycans such as decorin/DCN, biglycan/BGN and fibronectin/FN1. Inhibits signaling mediated by TGF-beta family proteins possibly indirectly by degradation of these ECM proteoglycans (By similarity). May act as a tumor suppressor. Negatively regulates, in vitro, trophoblast invasion during placental development and may be involved in the development of the placenta in vivo. May also have a role in ovarian development, granulosa cell differentiation and luteinization (PubMed:21321049, PubMed:22229724). Homotrimer (PubMed:26110759). Interacts with TGFB1; the interaction inhibits TGFB-mediated signaling. Interacts with BMP4; the interaction inhibits BMP4-mediated signaling. Interacts with TGFB2 and GDF5 (By similarity). Interacts with MYH9.
