PROTEIN
PHYSICAL PROPERTIES
STRUCTURE
motifs/domains
  • an N-terminal kinase domain
  • four cysteine-rich kringle domains
  • heterodimeric transmembrane glycoprotein (beta=150kD, alpha=35kD)
  • two carboxy-terminal nuclear export signals (NES)
  • conjugated GlycoP
    HOMOLOGY
    interspecies homolog to hippo
    intraspecies paralog to HGF
    Homologene
    FAMILY
  • peptidase S1 family
  • plasminogen subfamily
  • CATEGORY signaling cytokine growth factor
    SUBCELLULAR LOCALIZATION extracellular
    basic FUNCTION
  • regulating macrophage migration, phagocytosis, and nitric oxide production
  • involved in the regulation of peripheral macrophage activation
  • has the potential to modulate inflammatory actions of microglia, which proposes novel aspects for the process of degeneration and/or regeneration of the brain
  • protein regulating the innate immune responses to bacterial ligands and may have a role in the pathogenesis of inflammatory bowel diseases
  • MST1/MST1R signaling seems to play at least some role in the pathogenesis of Merkel cell carcinoma
  • may be one of the major determinants that affects the properties of tumor stroma and that produces a permissive microenvironment to promote cancer metastasis
  • is a positive regulator of mammary gland ductal morphogenesis by controlling overall epithelial cell turnover, macrophage recruitment, and STAT3 activation in the developing mammary gland
  • MST1/MST1R play important roles in inflammation, cell growth, migration, and epithelial to mesenchymal transition during tumor development
  • appears to promote the migration of fibroblasts, enhances collagen synthesis and remodeling, and effectively improves wound healing
  • hepatokine that potentially has a beneficial role in hepatic lipid and glucose metabolism via the activation of AMP-activated protein kinase (AMPK)
  • is an effective inhibitor of inflammation and lipid accumulation in the stressed liver, thereby indicating that it has a key regulatory role in Non-alcoholic steatohepatitis (NASH)
  • MST1 controlled inflammation response and mitochondrial function in endothelial cells
  • MST1 is the primary factors responsible for endothelial cells dysfunction in aneurysms formation through inducing inflammation response, endothelial apoptosis, and NFKB1 signaling pathway activation

    PATHWAY

    signaling
    a component
  • MST1/MST1R system promotes wound healing and invasive tumor growth and suppresses proinflammatory immune response
  • INTERACTION
    DNA
    RNA
    small molecule
    protein
  • MST1R ligand
  • interacting with RCC1 (RCC1 immobilization on the chromosomes at early stages of apoptosis is dependent on MST1 and its phosphorylation of histone H2B)
  • major determinant of RASSF2 protein stability
  • interacts strongly with RASSF5 but only weakly other components of the mammalian Hippo signaling pathway
  • TMPRSS11D is likely important for MST1-MST1R signaling in the respiratory tract
  • SAFB bound to AR and phosphorylated by MST1, previously shown to be an AR repressor, and MST1 localization to AR-dependent promoters was inhibited by SAFB depletion
  • through binding to its receptor, RON or MST1R), it can activate epithelial cells and work as an inflammatory mediator
  • cell & other
    REGULATION
    Other MST1 kinase activity is regulated by RASSF2 via RASSF2-MST1 protein complex formation
