    Anti-Nsp1p antibody [32D6]
  • 製品の詳細
    Mouse monoclonal [32D6] to Nsp1p
  • 特異性
    This antibody was initially identified as directed against a nuclear pore complex antigen by immunofluorescence localization. A screen of a lgt11 expression library yielded a single positive clone carrying an insert bearing ~66% of the C-terminal portion of NSP1. To confirm that 32D6 possessed high affinity for Nsp1p, strain RS453, which expresses a shortened isoform of Nsp1p, was compared to the wildtype strain BJ5465. NSP1 in RS453 contains an internal deletion that removes the coding sequence for 6 FXFG repeats, which are not essential for function and encodes a protein that has been observed to migrate at approxmately 85 kDa on SDS gels. The predicted size of wildtype Nsp1p is 86.5 kDa, but Nsp1p has been observed to migrate on SDS gels at ~100 kDa. In our gels, the apparent molecular mass of wildtype Nsp1p was 108 kDa, whereas the short isoform of Nsp1p in RS453 migrated at 91 kDa. The detection of two protein bands of apparent sizes 108 kDa and 91 kDa in BJ5465 and RS453, respectively, demonstrated that 32D6 recognized the pore complex protein Nsp1p.

    NSP1 functions as a component of the nuclear pore complex (NPC). It plays an important role in several nuclear transport pathways including poly(A)+ RNA, tRNA, pre-ribosome, signal recognition particle (SRP), and protein transport.
  • 細胞内局在
    Nuclear membrane: part of the nuclear pore complex, it presents a symmetric distribution with a cytoplasmic and a nucleoplasmic side.
