CC   -!- FUNCTION: Completely dephosphorylates 'Ser-2', and partially 'Ser-5'
CC       and 'Ser-7' of the heptad repeats YSPTSPS in the C-terminal domain
CC       (CTD) of the largest RNA polymerase II subunit (RPB1)
CC       (PubMed:25464831). Involved in defense response (PubMed:25464831). Acts
CC       as negative regulator of immune gene expression and immunity to
CC       pathogen infections (PubMed:25464831). Preferentially dephosphorylates
CC       'Ser-2' of RNA polymerase II CTD (PubMed:25464831). This
CC       counterregulates the MAP kinase (MAPK) or cyclin-dependent kinase C
CC       (CDKC)-mediated phosphorylation of CTD in response to pathogens and
CC       upon perception of microbe-associated molecular patterns (MAMPs)
CC       (PubMed:25464831). MAPKs phosphorylate and activate CDKCs, which are
CC       CTD kinases that positively regulate plant innate immunity
CC       (PubMed:25464831). Acts as negative regulator of stress gene
CC       transcription involved in abscisic acid (ABA) mediated signaling
CC       pathway and cold resistance (PubMed:12149434, PubMed:16905668). Acts as
CC       post-transcriptional gene silencing (PTGS) suppressor
CC       (PubMed:31076735). {ECO:0000269|PubMed:12149434,
