  • a short N-terminal RANBP2 fragment harboring the NPC-binding domain, three phenylalanine-glycine motifs, and one Ran-binding domain (RBD) corrected all transport defects and restored viability
  • a leucine-rich region (LRR)
  • a TPR domain
  • four potential RAN binding sites
  • eight zinc finger motifs
  • a kinesin-binding domain (KBD)
  • an internal repeat domain (IR1-M-IR2) that catalyzes E3 ligase activity and forms a stable complex with SUMO-modified RANGAP1 and UBE2I at the nuclear pore complex
  • a C terminal cyclophylin A homologous domain and nucleoporin repeat motifs (FXFG, GLFG, XXFG)

    SUBCELLULAR LOCALIZATION     intracellular
    intracellular,nuclear envelope,pore
  • cytoplasmic filaments of NPC
  • resides on the cytoplasmic face of the interphase nuclear pore complex
  • localizes to metaphase spindles and kinetochores in a microtubule-dependent manner
  • located on the cytoplasmic surface of the nuclear pore
  • ligase E3, RANBP2 was exclusively localized in the nucleus with homogeneous distribution in ocular cell lines
  • basic FUNCTION
  • nucleocytoplasmic transport, pre-mRNA processing, involved in cell-cycle progression, stimulator of UBL1 modification (sumoylation SUMO E3 ligase activity)
  • playing a role in regulating interphase microtubules
  • having a kinesin-dependent role in mitochondria transport and function
  • activate the ATPase activity of KIF5B approximately 30-fold in the presence of microtubules and ATP
  • during interphase, its nuclear envelope-associated functions include facilitation of protein import and export and sumoylation of protein cargoes
  • cooperates with kinesin-2 to regulate the localization of APC to the cell cortex through a nuclear-transport-independent mechanism
  • host factor that is involved in the nuclear import of HIV-1 PIC (DNA), but is not critical to the nuclear export of the viral mRNAs or nucleo-cytoplasmic shuttling of Rev
  • potentially playing a role in myogenesis
  • acts as a negative regulator of cAMP signaling through RAPGEF3, a cAMP-regulated guanine nucleotide exchange factor for Rap
  • critical function of RANBP2 is to capture recycling RANGTP-KPNB1 complexes at cytoplasmic fibrils to allow for adequate classical nuclear localization signal-mediated cargo import

  • constituent of the nuclear pore complex (NPC) with RANBP1, RANGAP1, UBE2I, exportin XPO1, importin beta, KPNB3, KIF5 motor proteins components of the 19S cap of 26S proteasome and opsin
  • RANBP2 forms a stable complex with SUMO-modified RANGAP1 and UBE2I at the nuclear pore complex
    small molecule
  • exportin (XPO1)
  • the E2 enzyme UBE2I (UBC9)
  • modifying HDAC4 and HDAC-1 and -6 deacetylases
  • modifying MITR
  • interacts with interphase microtubules through its N-terminal region and modulates their stability
  • through kinesin-binding domain (KBD) associated selectively in the central nervous system (CNS), and directly, with the ubiquitous and CNS-specific kinesins, KIF5B and KIF5C, respectively, but not with the highly homologous KIF5A
  • APC interacts with RANBP2, a microtubule-binding nucleoporin
  • with RAN, anchor RAPGEF3 to the nuclear pore, permitting cAMP signals to activate RAP1A at the nuclear envelope)
  • KPNB1 having functions at kinetochores exerted via RANBP2 and opposed by XPO1
  • cellular RANBP2 is quantitatively associated with RANGAP1, indicating that complexed rather than free RANBP2 is the relevant E3 ligase
  • nuclear transport receptors KPNB1 and XPO1 play essential roles in localising the RANBP2-SUMO-RANGAP1 complex away from, or at kinetochores, respectively
