Integrator complex subunit 12 (INTS12)

Part 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 linked to the C-terminal domain (CTD) of RNA polymerase II largest subunit (POLR2A) and is recruited to the U1 and U2 snRNAs genes (PubMed:16239144).

Mediates recruitment of cytoplasmic dynein to the nuclear envelope, likely as part of the INT complicated (PubMed:23904267). .
