General notesab94064 is a 293T cell transfected lysate in which Human RanGAP1 has been transiently over-expressed using a pCMV-RanGAP1 plasmid. The lysate is provided in 1X Sample Buffer.
Note: For more detailed how the transfected lysate was prepared view preparation notes
BackgroundFunction: GTPase activator for the nuclear Ras-related regulatory protein Ran, converting it to the putatively inactive GDP-bound state.
PTM: Phosphorylated 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 with 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.
Similarity: Belongs to the RNA1 family.
Contains 6 LRR (leucine-rich) repeats.
Tissue specificity: Highly expressed in brain, thymus and testis.
