cell lines
  • a Src homology 3 (SH3) domain
  • one immunoreceptor tyrosine-based activation motif (ITAM)
  • N-terminal 191 AAs which contain both VHS and ubiquitin binding motif (UIM),(VHS domains, binding to ubiquitin via its hydrophobic patch consisting of N-terminus of helix 2 and C-terminus of helix 4)
  • a coiled-coil region that overlaps with ITAM required for interactions TIMM8A-STAM
  • STAM family
  • CATEGORY adaptor , signaling
    SUBCELLULAR LOCALIZATION     intracellular
  • localizes predominantly to early endosomes (localize to endosomal membranes)
  • localize prominently to early exocytic compartments and profoundly regulate Golgi morphology
  • basic FUNCTION
  • signal-transducin adaptor molecule involved in cytokine-mediated signal transduction
  • involved in growth factor and cytokine signaling as well as receptor degradation, and they form complexes with a number of endocytic proteins, including HGS and EPS15
  • in addition to their roles in signaling and endocytosis, function prominently in ER-to-Golgi trafficking, most likely through direct interactions with the COPII complex
    signaling signal transduction
    a component
  • HGS (hepatocyte growth factor-regulated tyrosine kinase substrate) and STAM (signal-transducing adaptor molecule) form a heterodimeric complex that associates with endosomal membranes and is tyrosine-phosphorylated in response to a variety of growth
  • ESCRT-0 complex is composed of two subunits, HGS and STAM, both of which can engage ubiquitinylated substrates destined for lysosomal degradation
  • crucial regulatory axis for the ventral axonal trajectory of developing spinal MNs, consisting of the ISL1-LHX3 complex, STAM1 and CXCR4
    small molecule
  • interaction with several cytoplasmic proteins involved in cell signaling and endosomal trafficking (with TIMM8A)
  • USP8Y binding partner
  • STAM-STAMBP interaction facilitates the deubiquitination activity in the C-terminal STAMBP
  • associating with USP8
  • interaction between ITCH and STAM and the ligase activity of ITCH are essential for ERK-1/2 activation
  • LITAF interacted and colocalized with endosomal sorting complex required for transport (ESCRT) components STAM, HGS, and TSG101 on early endosomes and functioned with the ESCRT machinery in the control of endosome-to-lysosome trafficking
  • STAMBP interacts with signal transducing adapter molecule (STAM) 1 or STAM2, which enhances the activity of STAMBP through an unknown mechanism
  • ARRB1 and STAM cooperate to promote focal adhesion kinase autophosphorylation and chemotaxis via the chemokine receptor CXCR4
  • USP8 interacts with and deubiquitinates SEC31A; the interaction was mediated by the adaptor protein STAM
  • cell & other
    induced by interleukin IL2
    Other phosphorylated by the JAK kinases upon cytokine stimulation (function of this protein is likely as an adaptor molecule involved in the downstream signaling of cytokine receptors)
