Purification of a Ran-interacting protein that is required for protein import into the nucleus.
Open accessAbstract
Previously we reported the isolation of two cytosolic fractions (A and B) from Xenopus ovary that are required sequentially to support protein import into the nuclei of digitonin-permeabilized cells. Fraction A is required for recognition of the nuclear localization sequence and targeting to the nuclear envelope, whereas fraction B is required for the subsequent translocation of the bound substrate into the nucleus. The first protein required for fraction B activity to be purified was the small GTPase Ran (ras-related nuclear protein). Here we report the purification of the second (and final) protein required for fraction B activity. By SDS/PAGE, the purified protein appeared as a single band with an apparent molecular mass of 10 kDa, but the native protein fractionated upon gel filtration chromatography with an apparent size of 30 kDa. Peptide sequence analysis indicated that the purified protein was highly homologous to a previously identified human protein of unknown function called placental protein 15 (pp15) and to the predicted protein product of a yeast open reading frame from Saccharomyces cerevisiae.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
