    FAMILY
  • beta-microseminoprotein family
  • immunoglobulin superfamily
  • CATEGORY regulatory , secretory
    SUBCELLULAR LOCALIZATION extracellular
    intracellular,nucleus
    basic FUNCTION
  • may have a role as an autocrine paracrine factor in uterine, breast and other female reproductive tissues
  • playing a role in hormonal control at the pituitary gonadal axis
  • functions as a suppressor of tumor growth and metastasis
  • CELLULAR PROCESS
    PHYSIOLOGICAL PROCESS
    PATHWAY
    metabolism
    signaling
    a component seminal plasma protein, forming a tight complex with cysteine-rich secretory protein 3 (CRISP3) from granulocytes
    INTERACTION
    DNA
    RNA
    small molecule
    protein
  • interacting with EZH2 (MSMB is silenced by EZH2 in advanced prostate cancer cells)
  • interact with cysteine-rich secretory protein 3 (CRISP3) in seminal plasma
  • both MSMB and an adjacent gene, NCOA4, are subjected to transcriptional control via androgen response elements
  • MSMB bind human CRISP3 (cysteine-rich secretory protein 3) with very high affinity
  • MSMB is a key upstream factor in mediating PRSS8 signaling that regulates PRSS8 expression and action in ovarian cancer cells
  • CRISP2 is a potential binding protein of MSMB
  • CRISP3 binds specifically and with high affinity to MSMB
  • cell & other
