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].
The beta-CASP domain is found C terminal to the beta-lactamase domain in pre-mRNA 3'-end-processing endonuclease. The active site of this enzyme is located at the interface of these two domains [1].
Integrator subunit 4 family C-terminal Ig-like domain
This entry represents the C-terminal domain of Integrator subunit 4 (INTS4). 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 ...
This entry represents the C-terminal domain of Integrator subunit 4 (INTS4). 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.
This domain is found in the homologs of Integrator complex subunit 4 (INTS4). INTS4 along with INTS9 and INTS11 constitute the Integrator cleavage module, which contains endonuclease activity and resembles the cleavage module of the cleavage and pol ...
This domain is found in the homologs of Integrator complex subunit 4 (INTS4). 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.
This family includes a diverse range of phosphoesterases [1], including protein phosphoserine phosphatases, nucleotidases, sphingomyelin phosphodiesterases and 2'-3' cAMP phosphodiesterases as well as nucleases such as bacterial SbcD Swiss:P13457 or ...

The most conserved regions in this superfamily centre around the metal chelating residues.

This entry represents a domain found in the human Integrator complex subunit 6 (INTS6) and related proteins, including its paralogue Integrator complex subunit 6-like (INTS6L). INTS6 is a component of the Integrator (INT) complex, a complex that is involved in the small nuclear RNAs (snRNA) U1 and U2 transcription and in their 3'-box-dependent processing. INTS6 and other subunits bind to and position PP2A phosphatase to dephosphorylate the C-terminal domain of Pol II subunit RPB1 [1,2]. In the inactive closed conformation of the INT-PP2A complex, INTS6 blocks the PP2A phosphatase active site. The domain represented by this entry folds into a beta-barrel structure with topological similarity to SPOC domains.

Integrator complex subunit 7 (INTS7) is a component of the integrator complex, a complex that is recruited to the U1 and U2 snRNA genes and mediates the snRNAs' 3' end processing. 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].
