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.
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].
