NUP1

FG-nucleoporin NUP1, L000001288, YOR098C

FG-nucleoporin component of central core of the nuclear pore complex; contributes directly to nucleocytoplasmic transport and maintenance of thenuclear pore complex (NPC) permeability barrier; possible karyopherin release factor that accelerates release of karyopherin-cargo complexes after transport across NPC; both NUP1 and NUP60 are homologous to human NUP153

KAP60, SCM1, karyopherin alpha, L000002755, L000002780, YNL189W

Karyopherin alpha homolog; forms a dimer with karyopherin beta Kap95p to mediate import of nuclear proteins, binds the nuclear localization signal of the substrate during import; involved in cotranslational protein degradation; binds ribosome-bound nascent polypeptides; Srp1p and Sts1p couple proteasomes to nascent polypeptides emerging from the ribosome for cotranslational degradation

A gradient of affinity for the karyopherin Kap95p along the yeast nuclear pore complex.

Pyhtila B, Rexach M

Karyopherins (Kaps) transport cargo across the nuclear pore complex (NPC) by interacting with nucleoporins that contain phenylalanine-glycine (FG) peptide repeats (FG Nups). As a test of the "affinity gradient" model for Kap translocation, we measured the apparent affinity of Kap95p to FG Nups representing three distinct regions of the S. cerevisiae NPC. We find that the affinity of Kap95p-Kap60p-cargo complexes ... [more]

NUP1 SRP1	Affinity Capture-Western Affinity Capture-Western An interaction is inferred when a bait protein is affinity captured from cell extracts by either polyclonal antibody or epitope tag and the associated interaction partner identified by Western blot with a specific polyclonal antibody or second epitope tag. This category is also used if an interacting protein is visualized directly by dye stain or radioactivity. Note that this differs from any co-purification experiment involving affinity capture in that the co-purification experiment involves at least one extra purification step to get rid of potential contaminating proteins.
