Species cross-reactivity is determined by western blot.
Applications Key: W=Western Blotting
Specificity / Sensitivity
RanBP1 Antibody recognizes endogenous levels of total RanBP1 protein.
Source / Purification
Polyclonal antibodies are produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Thr193 of human RanBP1 protein. Antibodies are purified by protein A and peptide affinity chromatography.
RanBP1 is a Ran binding protein that functions in nuclear trafficking for both nuclear import and export (1-3). Its protein sequence contains a Ran binding domain and a C-terminal nuclear export signal, which maintains its cytoplasmic localization (2,3). During nuclear export, RanBP1 forms a complex with RanGTP and CRM1/cargo, leading to dissociation of cargo from CRM1 (2,4). RanBP1 further stimulates RanGTP-RanGAP1 association to facilitate RanGTP hydrolysis and the generation of RanGDP to complete the final steps of nuclear export (5). During nuclear import, RanBP1 stabilizes the formation of a RanGDP-importin/NLS receptor-RanBP1 complex. This complex regulates the release of imported cargo into the nucleus (6,7). In addition to nuclear trafficking, RanBP1 also controls RanGTP distribution along mitotic microtubules, which localizes critical factors, such as cyclin B1 and HURP, to mitotic microtubles and regulates chromosome segregation (8,9). In vivo knock down or overexpression of RanBP1 has been shown to affect cellular ciliogenesis by regulating the local RanGTP concentation at the base of cilia (10).
