Plays a role in the recruitment of the RNA exosome complex to pre-rRNA to mediate the 3'-5' end processing of the 5.8S rRNA; this function may include MPHOSPH6. Can activate PRKDC not only in the presence of linear DNA but also in the presence of supercoiled DNA. Can induce apoptosis in a p53/TP53 dependent manner. May regulate the TRAX/TSN complex formation. Potentiates transcriptional repression by NR1D1 and THRB.

C1D is associated with the DNA repair complex and may promote repair of ultraviolet irradiation-induced DNA damage. PMID: 20530579
Results are consistent with a role for the exosome-associated protein C1D in the recruitment of the exosome to pre-rRNA to mediate the 3' end processing of the 5.8S rRNA. PMID: 17412707
Anti-C1D autoantibodies were observed in patients with polymyositis-scleroderma overlap syndrome. PMID: 17599775
TRAX enhances the DNA binding capacity of Translin, that binds to recombination regions in some malignancies. C1D interacts with TRAX following g-irradiation and prevents formation of TRAX/Translin complex, thereby inhibits any unwanted recombination. PMID: 11801738
The C1D protein interacts with the catalytic subunit of DNA-PK and is a very effective substrate for DNA-PK in vitro. Moreover, C1D directs the activation of DNA-PK in a manner that does not require DNA termini, suggesting a role for C1D in DNA repair. PMID: 9679063
