INTS1 is a subunit of the Integrator complex, which associates with the SLCterminal domain of RNA polymerase II large subunit (POLR2A; MIM 36660) and mediates 3-prime end processing of small nuclear RNAs U1 (RNU1; MIM 36136) and U2 (RNU2; MIM 36690) (Baillat et al., 2005 [PubMed 16239144]).[supplied by OMIM, Mar 2008]
Function:
Component of the Integrator complex, a complex involved in the small nuclear RNAs (snRNA) U1 and U2 transcription and in their 3'-box-dependent processing. The Integrator complex is associated with the SLCterminal domain (CTD) of RNA polymerase II largest subunit (POLR2A) and is recruited to the U1 and U2 snRNAs genes.
Subcellular Location:
Nucleus membrane.
Similarity:
Belongs to the Integrator subunit 1 family.
