Product details

Ran is a small signaling GTPase that is involved in nucleocytoplasmic transport. Two additional functions of animal Ran in the formation of spindle asters and the reassembly of the nuclear envelope in mitotic cells have been recently reported. In contrast to Ras or Rho, Ran is not associated with membranes. Instead, the spatial sequestering of its accessory proteins, the Ran GTPase-activating protein RanGAP 1 and the nucleotide exchange factor RCC1, appears to define the local concentration of RanGTP vs. RanGDP involved in signaling. Mammalian RanGAP 1 is bound to the nuclear pore by a mechanism involving the attachment of small ubiquitin-related modifier protein (SUMO) to its C terminus and the subsequent binding of the SUMOylated domain to the nucleoporin Nup358.

Supplementary information

This supplementary information is collated from multiple sources and compiled automatically.

RanGAP1 also known as Ran GTPase-activating protein 1 plays an important role in regulating nucleocytoplasmic transport. Mechanically it converts RanGTP to RanGDP in the cytoplasm which is essential for the recycling of Ran and maintenance of the Ran gradient across the nuclear envelope. The molecular mass of RanGAP1 is approximately 70 kDa. RanGAP1 is expressed in various cell types with significant presence in the cytoplasm due to its function.
Biological function summary

Many cellular processes rely on the action of RanGAP1 as it forms part of the Ran cycle. This protein is an integral component of the nuclear transport complex which regulates the bidirectional movement of RNA and proteins through the nuclear pores. Through its action RanGAP1 indirectly influences nuclear import and export playing an essential part in cell cycle regulation and mitosis.

Pathways

Several key cellular pathways are dependent on RanGAP1 activity. For instance it is a component of the mitotic spindle assembly pathway and also plays a role in the RNA processing pathway. In these pathways RanGAP1 works closely with other proteins such as RanBP1 and RCC1 facilitating important cellular events that require strict regulation of nuclear-cytoplasmic transport.

Disruptions in RanGAP1 function have been associated with certain types of cancer and neurodegenerative diseases. Aberrant regulation of RanGAP1 activity can lead to improper cell cycle progression contributing to oncogenesis. Furthermore changes in the expression of RanGAP1 and its interacting proteins like RanBP2 may relate to disorders like Huntington's disease where cellular transport mechanisms are compromised.

GTPase activator for RAN (PubMed : 16428860, PubMed : 8146159, PubMed : 8896452). Converts cytoplasmic GTP-bound RAN to GDP-bound RAN, which is essential for RAN-mediated nuclear import and export (PubMed : 27160050, PubMed : 8896452). Mediates dissociation of cargo from nuclear export complexes containing XPO1, RAN and RANBP2 after nuclear export (PubMed : 27160050).
