Focus of the RCC1 gene

RCC1----Crm1---Ran guanine nucleotide exchange factor
according to Nemergut:" RanBP3 acts as a scaffold protein to promote the efficient assembly of export complexes."
from REN : "These results are consistent with the hypothesis that Ran functions directly in at least two pathways, one, dependent on RanBP1, that affects cell cycle progression and RNA export, and another, independent of RanBP1, that affects nuclear protein import."

Paschal et al :"
the nuclear guanine nucleotide exchange factor (RanGEF), and the Ran import receptor (NTF2). The recent identification of the Saccharomyces cerevisiae protein Mog1p as a suppressor of temperature-sensitive Ran mutations suggests that additional regulatory proteins remain to be characterized."

Dig this by REN et al! and you will understand that the anti-VEGF is still the begining of the membrane The small Ras-related GTP binding and hydrolyzing protein Ran has been implicated in a variety of processes, including cell cycle progression, DNA synthesis, RNA processing, and nuclear-cytosolic trafficking of both RNA and proteins. Like other small GTPases, Ran appears to function as a switch: Ran-GTP and Ran-GDP levels are regulated both by guanine nucleotide exchange factors and GTPase activating proteins, and Ran-GTP and Ran-GDP interact differentially with one or more effectors.story:
