RanGAP1 protein (Tagged-His Tag) (ab91719)
This protein was expressed as an N-terminal His-tag fusion protein using Escherichia coli, and purified using Immobilized Metal Ion Affinity Chromatography. In some cases, smaller protein fragments may be present in addition to the intended expression product as a result of premature termination during translation in E. coli and subsequent co-purification via the His-tag. In some cases purified proteins run at a molecular weight different to the theoretically calculated molecular weight. This may be as a result of unequally distributed charges in the amino acid sequence. Alternatively, dimerisation of the expression product can occur under oxygen limitation during expression/cultivation.

Contains 6 LRR (leucine-rich) repeats.
modificationsPhosphorylated occurs before nuclear envelope breakdown and continues throughout mitosis. Phosphorylated by the M-phase kinase cyclin B/Cdk1, in vitro. Differential timimg of dephosphorylation occurs during phases of mitosis. The phosphorylated form remains associated with RANBP2/NUP358 and the SUMO E2-conjugating enzyme, UBC9, on nuclear pore complex (NPC) diassembly and during mitosis.
Sumoylated by SUMO1. Sumoylation is necessary for targeting to the nuclear envelope (NE), and for association with mitotic spindles and kinetochores during mitosis. Also required for interaction with RANBP2 and is mediated by UBC9.
