NCBI Protein Information
carboxyl-terminal domain (ctd) phosphatase-like 2
NCBI Summary
Encodes CPL2, a carboxyl-terminal domain (CTD) phosphatase that dephosphorylates CTD Ser5-PO4 of the RNA polymerase II complex. Regulates plant growth, stress and auxin responses.

UniProt Comments
Processively dephosphorylates 'Ser-5' but not 'Ser-2' of the heptad repeats YSPTSPS in the C-terminal domain of the largest RNA polymerase II subunit (RPB1). This promotes the activity of RNA polymerase II. Together with CPL1, required for male gametes fertility. Multifunctional regulator that modulates plant growth, stress, and phytohormones responses. Positive transcription regulator of genes involved in high salinity resistance and auxin mediated signaling pathway.
