F-cell production 1 (FCP1) also called TFIIF-stimulated CTD phosphatase 1 (CTDP1), prefers to dephosphorylate pSer2 of heptapeptide repeats at CTD of RNA polymerase II. The molecular function is mainly studied in yeast [1].
Evolution
FCP1 is conserved from yeast to human, usually one copy per genome.
Domain Structure
In additional to the catalytic domain, it has a breast cancer protein-related carboxy-terminal (BRCT) domain and a C-terminal region that binds regulatory TFIIF.
Functions
FCP1 preferentially hydrolyzes Ser2 in CTD repeats in budding yeast [1] and fission yeast [2].
Substrates and Related Kinases
See Phosphorylation of RNA polymerase II C-terminal domain.
