NAB2

mRNA-binding protein NAB2, L000001227, YGL122C
Nuclear polyadenylated RNA-binding protein; required for nuclear mRNA export and poly(A) tail length control; binds nuclear pore protein Mlp1p; involved in forming export-competent mRNPs in the nucleus; autoregulates mRNA levels; related to human hnRNPs; nuclear localization sequence binds Kap104p; protein abundance increases in response to DNA replication stress

Affinity Capture-RNA

An interaction is inferred when a bait protein is affinity captured from cell extracts by either polyclonal antibody or epitope tag and associated RNA species identified by Northern blot, RT-PCR, affinity labeling, sequencing, or microarray analysis.

An elevated level of the mRNA exporter Mex67-Mtr2 in nuclear mRNPs impairs nuclear mRNA export.

Stefanyshena N, Straesser K

In eukaryotes, nuclear messenger RNA (mRNA) export is a crucial step in gene expression, mediated by the conserved mRNA exporter Mex67-Mtr2 in Saccharomyces cerevisiae and NXF1-NXT1 in humans. Mex67-Mtr2 is recruited to the mRNA by the adaptors Hpr1, Nab2, Yra1, and Npl3, which play important yet incompletely understood roles in this process. Here, we uncover that, counterintuitively, an excess of ... [more]
