Involved in DNA damage checkpoint signaling; cellular response to ionizing radiation; and snRNA processing. Located in chromosome; cytoplasm; and nuclear body. Part of integrator complex. Is active in nucleus.
RGD Description
This gene encodes a subunit of the integrator complex. The integrator complex associates with the C-terminal domain of RNA polymerase II and mediates 3'-end processing of the small nuclear RNAs U1 and U2. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene. [provided by RefSeq, Dec 2010]
