Component of the Integrator complex, a complex involved in the transcription of small nuclear RNAs (snRNA) and their 3'-box-dependent processing. Involved in the 3'-end processing of the U7 snRNA, and also the spliceosomal snRNAs U1 and U5. 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 INTS14 family.
