In mouse Nore1, the C1 domain forms an intramolecular complex with the RA domain that weakens Ras/Rap1-GTP binding; GTP-Ras binding to the RA domain disrupts this C1-RA intramolecular complex, making the C1 domain's lipid-binding interface accessible; the free C1 domain binds phosphatidylinositol 3-phosphate. |

RASSF5/RAPL contains functional nuclear export signal (NES, aa 260–300) dependent on CRM-1, and two nuclear localization signals; Lck tyrosine kinase binds RASSF5 through its C-terminal SH2-binding motif and phosphorylates it, which is required for efficient nuclear import of RASSF5; nuclear-localized (ΔNES) RASSF5 causes G1/S arrest and apoptosis, while an Lck-interaction-defective mutant induces apoptosis without cell cycle arrest. |

Crystal structures of human Mst2 alone and in complex with RASSF5 SARAH domain reveal that: (i) Mst2 activates by transautophosphorylation at its activation loop requiring SARAH-mediated homodimerization; (ii) RASSF5 SARAH disrupts the Mst2 homodimer and blocks Mst2 autoactivation when bound before activation-loop phosphorylation; (iii) RASSF5 binding to already-activated Mst2 does not inhibit kinase activity—suggesting RASSF5 can be either inhibitor or positive regulator depending on the timing of binding relative to Mst2 activation. |
