    FAMILY
  • peptidase S1B family, HTRA family
  • CATEGORY enzyme , regulatory
    SUBCELLULAR LOCALIZATION extracellular
    basic FUNCTION
  • acting as a serine-type endopeptidase
  • involved in placentation
  • is an inhibitor of trophoblast invasion during placental development
  • decidual HTRA3 negatively regulates trophoblast invasion.
  • is important for placental development and cancer progression
  • HTRA1 and HTRA3 are crucial for trophoblast-decidual cell interaction in the control of trophoblast invasion
  • involved in the pathogenesis of ovarian cancer
  • HTRA1, HTRA2, HTRA3, HTRA4 function as important modulators of many physiological processes, including maintenance of mitochondrial homeostasis, cell signaling and apoptosis
  • HTRA3 protease is a proapoptotic protein, involved in embryo implantation and oncogenesis
  • CELLULAR PROCESS cell life, proliferation/growth
