The protein encoded by KIAA1530 appears to be involved in ubiquitination and dephosphorylation of RNA polymerase II subunits that stall after UV irradiation. The encoded protein interacts with several members of the nucleotide excision repair complex, and is thought to be involved in the transcription-coupled nucleotide excision repair (TC-NER) pathway to help remove lesions in the DNA that block transcription. Defects in KIAA1530 can cause UV-sensitive syndrome 3. Alternative splicing results in multiple transcript variants.
