Integrator complex subunit 12 (Int12) also known as PHD finger protein 22 (PHF22) is a protein that in humans is encoded by the INTS12gene.[4]
INTS12 is a subunit of the Integrator complex, which associates with the C-terminal domain of RNA polymerase II large subunit (POLR2A) and mediates 3-prime end processing of small nuclear RNAs U1 (RNU1) and U2 (RNU2)[4][5]
