Phosphatase Classification: Fold HAD: Superfamily HAD: Family FCP: Subfamily FCP1
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 (FCP1_C) that binds regulatory TFIIF.
The FCP1_C domain is found widely in deuterosomes (from sea urchin to chordates). It is absent from some proteostomes. It is present in basal eumetazoan Nematostella. It is probably FCP1_C domain was gained in eumetazoa, but was lost in multiple independent events. See technical notes.
Functions
FCP1 preferentially hydrolyzes Ser2 in CTD repeats in budding yeast [1] and fission yeast [2].
See Phosphorylation of RNA polymerase II C-terminal domain.
