IntS11 is the catalytic component of integrator complex (INT), which is involved in the small nuclear RNAs (snRNA) U1 and U2 transcription and in their 3'-box-dependent processing. This is the C-terminal domain of IntS11 which interacts with the C-terminal of IntS9 (Pfam:PF21382), which is a crucial interaction for the role of INT in snRNA 3'-end processing [1,2]. IntS11 is responsible of the endonuclease activity of INT [1-3].	Domain
