(Cleavage and Polyadenylation Specific Factor 3-Like (CPSF3L))
The Integrator complex contains at least 12 subunits and associates with the C-terminal domain of RNA polymerase II large subunit (POLR2A\; MIM 180660) and mediates the 3-prime end processing of small nuclear RNAs U1 (RNU1\; MIM 180680) and U2 (RNU2\; MIM 180690). INTS11, or CPSF3L, is the catalytic subunit of the Integrator complex (Baillat et al., 2005 [PubMed 16239144]).[supplied by OMIM, Mar 2008].
