IPR005574 is a RNA polymerase subunit Rpb4/RPC9.
<p>This entry includes RNA polymerase II subunit Rpb4 and its paralogue, RPC9 (also known as Rpc17 in budding yeasts), a subunit of RNA polymerase III [[cite:PUB00088484]]. The Rpb4 and Rpb7 subunits of yeast RNA polymerase II form a heterodimeric complex essential for promoter-directed transcription initiation. The Rpb4-Rpb7 complex is not required for stable recruitment of polymerase to active preinitiation complexes, suggesting that Rpb4-Rpb7 mediates an essential step subsequent to promoter binding [[cite:PUB00007967]]. RPC9 may be involved in the recruitment of pol III by the preinitiation complex [[cite:PUB00056255], [cite:PUB00088483]].</p>

GO predictions are based solely on the InterPro-to-GO mappings published by EMBL-EBI, which are in turn based on the mapping of predicted domains to the InterPro dataset. The InterPro-to-GO mapping was last updated on , while the GO metadata was last updated on .
| GO term | Namespace | Name | Definition | Relationships |
|---|---|---|---|---|
| Biological process | DNA-templated transcription, initiation | Any process involved in the assembly of the RNA polymerase preinitiation complex (PIC) at the core promoter region of a DNA template, resulting in the subsequent synthesis of RNA from that promoter. The initiation phase includes PIC assembly and the formation of the first few bonds in the RNA chain, including abortive initiation, which occurs when the first few nucleotides are repeatedly synthesized and then released. The initiation phase ends just before and does not include promoter clearance, or release, which is the transition between the initiation and elongation phases of transcription. | ||
| Cellular component | RNA polymerase complex | Any complex that possesses RNA polymerase activity; generally comprises a catalytic subunit and one or more additional subunits. |
