Species cross-reactivity is determined by western blot.
Applications Key: W=Western Blotting, IP=Immunoprecipitation,
Specificity / Sensitivity
Importin β1 (E1F1G) Rabbit mAb recognizes endogenous levels of total importin β1 protein.
Source / Purification
Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Asn486 of human importin β1 protein.
Immunoprecipitation of Importin β1 from HeLa cell extracts. Lane 1 is 10% input, lane 2 is Normal Rabbit IgG #3900, and lane 3 is Importin β1 (E1F1G) Rabbit mAb. Western blot analysis was performed using Importin β1 (E1F1G) Rabbit mAb.
Importins belong to the karyopherin family of nuclear transport proteins (1) and are divided into two subgroups: importin α and importin β. Importins mainly function in nuclear protein import and export (2,3). Importin β1 (also known as karyopherin β1, Kpnβ1, Kpnb1, or p97) plays a key role in the nuclear import process (1-3). Nuclear import via importin β1 association with adaptor importin α (also known as karyopherin α, or Kpnα) is an essential component of the classical nuclear localization signal (NLS) pathway (4). Importin α directly recognizes the NLS present in the cargo target, prompting complex formation with importin β1. The cargo:importin α:importin β1 complex is transported across the nuclear pore complex (NPC) into the nucleus, where it is dissociated by the binding of RanGTP (1-4). Nuclear import directly via importin β1 can also occur by importin β1 recognition of the cargo protein, bypassing importin α involvement. In both cases, the importin β1/target protein interaction is mediated through the binding of importin β1 HEAT repeats with the target protein sequences (either the cargo protein itself or importin α) (5).
