Phosphatase Classification: Fold HAD: Superfamily HAD: Family FCP: Subfamily FCP1


F-cell production 1 (FCP1) also called TFIIF-stimulated CTD phosphatase 1, 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.
