DNA repair protein REV1 is a protein that in humans is encoded by the REV1 gene. [5] [6]
This gene encodes a protein with similarity to the S. cerevisiae mutagenesis protein Rev1. The Rev1 proteins contain a BRCT domain, which is important in protein-protein interactions. A suggested role for the human Rev1-like protein is as a scaffold that recruits DNA polymerases involved in translesion synthesis (TLS) of damaged DNA. Two alternatively spliced transcript variants that encode different proteins have been found. [6]
Rev1 is a Y family DNA polymerase; it is sometimes referred to as a deoxycytidyl transferase because it only inserts deoxycytidine (dC) across from lesions. Whether G, A, T, C, or an abasic site, Rev1 will always add a C. Rev1 has the ability to always add a C, because it uses an arginine as a template which complements well with C. [7] Yet it is believed[ by whom? ] that Rev1 rarely uses its polymerase activity; rather it is thought that Rev1's primary role is as a protein landing pad, whereby it helps direct the recruitment of TLS proteins, especially Pol ζ (Rev3/Rev7).
REV1 has been shown to interact with MAD2L2. [8] It is believed that Rev1 may interact with PCNA, once ubiquitylated due to a lesion, and help recruit Pol ζ (Rev3/Rev7) a B family polymerase involved in TLS.
DNA-directed RNA polymerase II subunit RPB1, also known as RPB1, is an enzyme that is encoded by the POLR2A gene in humans.
DNA-directed RNA polymerases I, II, and III subunit RPABC1 is a protein that in humans is encoded by the POLR2E gene.
Replication protein A 70 kDa DNA-binding subunit is a protein that in humans is encoded by the RPA1 gene.
DNA replication licensing factor MCM7 is a protein that in humans is encoded by the MCM7 gene.
DNA polymerase kappa is a DNA polymerase that in humans is encoded by the POLK gene. It is involved in translesion synthesis.
Mitotic spindle assembly checkpoint protein MAD2B is a protein that in humans is encoded by the MAD2L2 gene.
DNA polymerase delta subunit 2 is an enzyme that in humans is encoded by the POLD2 gene. It is a component of the DNA polymerase delta complex.
Protein reversionless 3-like (REV3L) also known as DNA polymerase zeta catalytic subunit (POLZ) is an enzyme that in humans is encoded by the REV3L gene.
Mediator of RNA polymerase II transcription subunit 17 is an enzyme that in humans is encoded by the MED17 gene.
Heat shock protein 75 kDa, mitochondrial is a protein that in humans is encoded by the TRAP1 gene.
Mediator of RNA polymerase II transcription subunit 31 is a protein in humans encoded by the MED31 gene. It represents subunit Med31 of the Mediator complex. The family contains the Saccharomyces cerevisiae SOH1 homologues. SOH1 is responsible for the repression of temperature sensitive growth of the HPR1 mutant and has been found to be a component of the RNA polymerase II transcription complex. SOH1 not only interacts with factors involved in DNA repair, but transcription as well. Thus, the SOH1 protein may serve to couple these two processes.
Galactosylgalactosylxylosylprotein 3-beta-glucuronosyltransferase 3 is an enzyme that in humans is encoded by the B3GAT3 gene.
Tankyrase-2 is an enzyme that in humans is encoded by the TNKS2 gene.
