Component of the Integrator complex, a complex involved in the transcription of small nuclear RNAs (snRNA) and their 3'-box-dependent processing (PubMed:21078872, PubMed:23097424). May be involved in the 3'-end processing of the spliceosomal snRNAs U1, U2, U4 and U5 but is probably not essential for 3'-end processing of the snRNA U7 (PubMed:21078872, PubMed:23097424). Belongs to the multiprotein complex Integrator, at least composed of IntS1, IntS2, IntS3, IntS4, omd/IntS5, IntS6, defl/IntS7, IntS8, IntS9, IntS10, IntS11, IntS12, asun/IntS13 and IntS14. Belongs to the Integrator subunit 10 family.
