Species cross-reactivity is determined by western blot.
Applications Key: W=Western Blotting, IP=Immunoprecipitation,
Specificity / Sensitivity
RanBP3 Antibody recognizes endogenous levels of total RanBP3 protein.
Source / Purification
Polyclonal antibodies are produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Asn274 of human RanBP3 protein. Antibodies are purified by protein A and peptide affinity chromatography.
Western blot analysis of extracts from U-118 MG, NIH/3T3, and Neuro-2a cells using RanBP3 Antibody.
RanBP3 was originally identified as RanGTP binding protein located in the nucleus and involved in the nuclear exporting process (1). It functions as a cofactor for CRM1 nuclear export by binding to CRM1, stabilizing the RanGTP-CRM1-cargo interaction and promoting complex association with nuclear pore proteins (2,3). In the absence of Ran-bound GTP, RanBP3 prevents binding of CRM1 complex to the nuclear pore complex. In addition to CRM1, RanBP3 also has been shown to bind to RanGEF-RCC1 and increase the guanine nucleotide exchange activity of RCC1 for RanGTP-CRM1-Cargo (1,4). In some cases, as with β-catenin and Smad2/3, RanBP3 binding may mediate the target protein nuclear export in a Ran-dependent, but CRM1-independent manner (5,6). RanBP3 is phosphorylated at Ser58 through the PI3K/Akt or ERK/RSK pathway. This phosphorylation is important for RanBP3 function in nuclear export, likely due to stimulation of RCC1 activity (7,8).
