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].

The integrator complex interacts with the C-terminal tail of the largest subunit of RNA-polymerase II to promote 3'-snRNA processing [1]. This entry represents the helical bundle (HB) of INTS7, localised between the superhelical alpha-solenoid (Pfam:PF24436) and the C-terminal beta- sandwich (Pfam:PF22965) [2]. INTS7 interacts with INTS1 and INTS2 making extensive contacts with each other, nucleating the assembly of the whole INTAC complex [2].

The domain has been structurally identified near the INTS9 beta-CASP domain but is poorly resolved in current structures, suggesting flexibility. INTS4 is a component of the Integrator complex which plays essential roles in snRNA 3' end processing and transcription termination. The specific function of the C-terminal domain remains to be determined.

INTS4 along with INTS9 and INTS11 constitute the Integrator cleavage module, which contains endonuclease activity and resembles the cleavage module of the cleavage and polyadenylation specific factor required for 3' processing of mRNA transcripts. The domain represented by this entry makes extensive contacts with INTS7 and stabilize the beta-CASP domain of INTS9 in the cleavage module [1,2]. It folds into an eight alpha-helical bundle.
