    basic FUNCTION
  • multifunctional protein, stimulating proliferation of aortic smooth muscle cells and Ras effector pathways
  • erythroid potentiating and cell growth-promoting activities
  • involved in the regulation of bone modeling and remodeling in normal developing human bone
  • inhibits all MMPs, except MMP14
  • reducing tumor growth when it's overexpressed
  • antiapoptotic activity
  • naturally occurring specific inhibitor of matrix metalloproteinases
  • inhibits MMP2 activity, protects against cell death and may be of significance in initiating repair processes and curtailing keratoconus
  • major serum factors that stimulate the induction of TIMP-1 mRNA in quiescent human gingival fibroblasts
  • survival factor of germinal center (GC) B cells functioning as a differentiating and survival factor of GC B cells by modulating CD44 and PTPN6 in the late centrocyte/post-GC stage, regardless of EBV infection
  • significantly inhibited both FAS- and activation-induced cell death of lymphocytes
  • leads to enlarged adipocytes in the state of overnutrition
  • plays an important role in promoting cell growth of breast cancer
  • regulates essential stem cell functions, and may also mediate signaling that affects gene expression and inhibits the growth and differentiation of these cells
  • important role of TIMP1 in protection and recovery from cutaneous photodamage because of its suppression of ECM degradation and inflammation
  • regulates extracellular matrix turnover and also promotes cell growth and has anti-apoptotic activity, which promotes malignant processes in tumor tissue
  • CELLULAR PROCESS cell life, antiapoptosis

    PHYSIOLOGICAL PROCESS development
    PATHWAY
    metabolism
    signaling
    a component
  • component with MMP9 (progelatinase B)
  • INTERACTION
    DNA
    RNA
    small molecule
    protein
  • binding MMPs in a 1:1 stoechiometry
  • activating RAS
  • emerges as a modulator of neuronal outgrowth and morphology in a paracrine and autrocrine manner through the inhibition, at least in part, of MMP2 and not MMP9
  • osteopontin increased TIMP1 secretion by peripheral blood monocytes
  • fine balance between CCNL1 and TIMP1, which may contribute to breast cancer development
  • HAS2 promotes breast cancer cell invasion by suppression of TIMP1
  • colocalizes with CD63 on the surface of mesenchymal stem cells (hMSCs)
  • MMP10 interacting with tissue inhibitors of metalloproteinases TIMP1 and TIMP2
  • MIR17 targets TIMP1 and TIMP2 to modulate cardiac matrix remodeling
  • cell & other
    REGULATION
