DNA cross-link repair 1A protein is a protein that in humans is encoded by the DCLRE1A gene.^[5]^[6]^[7]

Function

The protein DCLRE1A (DNA cross-link repair 1A) is also referred to as SNM1A (sensitive to nitrogen mustard 1A). DCLRE1A is a 5’ to 3’ exonuclease that forms a complex with the Cockayne syndrome B (CSB) protein. In this complex, CSB modulates the exonuclease activity of DCLRE1A and coordinates the efficient assembly of DCLRE1A to sites of DNA damage.^[8] In human cells, this complex is recruited to DNA inter-strand cross-links, a form of DNA damage. The complex then participates in the repair of the cross-linked DNA. DCLRE1A protein is thought to be recruited by CSB to facilitate cross-link unhooking following incision 5’ to the cross-link by another complex, the ERCC1/XPF nuclease complex.^[8] Failure of the DCLRE1A/CSB complex to carry out its repair function may contribute to the degenerative pathologies and premature aging features of Cockayne syndrome.

The proto-oncogene c-Rel is a protein that in humans is encoded by the REL gene. The c-Rel protein is a member of the NF-κB family of transcription factors and contains a Rel homology domain (RHD) at its N-terminus and two C-terminal transactivation domains. c-Rel is a myeloid checkpoint protein that can be targeted for treating cancer. c-Rel has an important role in B-cell survival and proliferation. The REL gene is amplified or mutated in several human B-cell lymphomas, including diffuse large B-cell lymphoma and Hodgkin's lymphoma.
