Early effects of cdkf;1 RNAPII CTD Serine-7 kinase mutation on regulation of transcription in 7 days old Arabidopsis seedlings
Ontology highlight
ABSTRACT: Serine phosphorylation of conserved Y1S2P3T4S5P6S7 repeats of RNA polymerase II carboxy-terminal domain (RNAPII CTD) plays a central role in the regulation of transcription and co-transcriptional RNA processing. Maintenance of CTD phosphoserine-7 mark in Arabidopsis requires the CDKF;1 kinase, which mediates in vivo activation of downstream-acting CDKD CTD kinase family. Knockout mutations of CDKF;1 lead to over 50% reduction of RNAPII CTD Ser-7 phosphorylation as early as 7 days after germination in seedlings. The transcript profiling experiment aimed at determining how early changes in CTD Ser-7 phosphorylation affect global regulation of transcription. We used Affymetrix ATH1-121501 Genome Array to compare global transcript levels in wild type and cdkf;1-2 mutant seedlings 7 days after germination.
