    SUBCELLULAR LOCALIZATION     intracellular
  • cytoskeletal localization is required for growth-suppressive effects
  • shuttles between the nucleus and the cytoplasm, and its export from the nucleus is sensitive to leptomycin B, suggesting that RASSF5 is exported from the nucleus by a XPO1-dependent export pathway (
  • basic FUNCTION
  • involved in neuropeptide signaling pathway, intracellular signaling cascade
  • regulating lymphocyte adhesion through the spatial distribution of ITGAL
  • cytoskeletal protein that suppresses growth by inhibition of the ERK pathway
  • nucleocytoplasmic shuttling protein, translocated into the nucleus and nucleolus via arginine-rich nuclear targeting signals
  • may function as tumour suppressors by regulating the cell cycle and apoptosis
  • induces apoptosis in a manner dependent on its nuclear export
  • mediates a negative effect of activated RAS on microtubule nucleation
  • plays an important role in mediating apoptosis in response to death receptor ligands, TNF and TNF-related apoptosis-inducing ligand
  • direct role for RASSF5 in death receptor ligand-mediated apoptosis
  • required for TNF-mediated apoptosis and for full activation of MST1

    small molecule metal binding,
  • Mg2+
  • protein
  • bind to the active Ras oncogene product
  • interacts with the tyrosine kinase LCK through its C-terminal Src homology 2 binding motif and LCK-mediated phosphorylation is critical for the efficient translocation of RASSF5 into the nuclear compartment
  • interacts strongly with MST1 but only weakly with other components of the mammalian Hippo signaling pathway
  • binds directly to the ITGB2 alpha chain cytoplasmic tail
  • interacting with SKAP1 (needed for RASSF5 binding to membranes in a manner dependent on the PH domain of SKAP1 and the PI3K pathway)
  • connection between SKAP1-RASSF5-TERF2IP and the PI3K pathway
  • can act as an inhibitor or a potential positive regulator of STK3, depending on whether it binds to STK3 before or after activation-loop phosphorylation
  • specific activation of RAP1B contributes to neuronal polarization via interaction with RALA and RASSF5 in addition to PI3-kinase
  • two effectors of RAP1A regulate integrins, RASSF5 and APBB1IP
