Gene

IWR1

Organism
Saccharomyces cerevisiae (strain ATCC 204508 / S288c) (Baker's yeast)
Status
Reviewed-Annotation score:

Annotation score:5 out of 5

<p>The annotation score provides a heuristic measure of the annotation content of a UniProtKB entry or proteome.

Directs RNA polymerase II nuclear import. Binds RNA polymerase II in the active center cleft between the two largest subunits in the cytoplasm. Then uses an N-terminal bipartite nuclear localization signal that may be recognized by karyopherin alpha to direct the polymerase II complex nuclear import. In the nucleus, is displaced from polymerase II complex by transcription initiation factors and nucleic acids, enabling its export and recycling.4 Publications

Miscellaneous

Present with 1080 molecules/cell in log phase SD medium.1 Publication

Caution

Due to the effects of deletion on gene expression, was originally thought to be a general transcription factor (PubMed:19679657). Further studies clearly suggest that it is involved in nuclear localization of the RNA polymerase II complex (PubMed:21504834).2 Publications

<p>The checksum is a form of redundancy check that is calculated from the sequence. It is useful for tracking sequence updates.</p> <p>It should be noted that while, in theory, two different sequences could have the same checksum value, the likelihood that this would happen is extremely low.</p> <p>However UniProtKB may contain entries with identical sequences in case of multiple genes (paralogs).</p> <p>The checksum is computed as the sequence 64-bit Cyclic Redundancy Check value (CRC64) using the generator polynomial: x<sup>64</sup> + x<sup>4</sup> + x<sup>3</sup> + x + 1.
