Gene Ontology Information

Protein Name	Rpb4p
Description	RNA polymerase II subunit B32; forms dissociable heterodimer with Rpb7p; Rpb4/7 dissociates from RNAPII as Ser2 CTD phosphorylation increases; Rpb4/7 regulates cellular lifespan via mRNA decay process; involved in recruitment of 3'-end processing factors to transcribing RNAPII complex, export of mRNA to cytoplasm under stress conditions; also involved in translation initiation
GO Terms: Biological Process	level 5: mRNA export from nucleus in response to heat stress level 7: DNA-templated transcription initiation level 7: nuclear-transcribed mRNA catabolic process, deadenylation-dependent decay level 7: mRNA processing level 7: RNA-templated transcription level 7: recruitment of 3'-end processing factors to RNA polymerase II holoenzyme complex level 8: transcription by RNA polymerase II level 8: transcription initiation at RNA polymerase II promoter level 9: positive regulation of translational initiation
GO Terms: Molecular Function	level 4: nucleotide binding level 4: translation initiation factor binding level 6: single-stranded DNA binding level 6: single-stranded RNA binding level 7: RNA-directed 5'-3' RNA polymerase activity
GO Terms: Cellular Component	level 3: cytoplasm level 4: RNA polymerase complex level 5: RNA polymerase II, core complex level 5: DNA-directed RNA polymerase complex level 5: P-body level 5: nucleus
