    basic FUNCTION
  • nuclease required for V(D)J recombination, the process by which exons encoding the antigen-binding domains of immunoglobulins and T-cell receptor proteins are assembled from individual V, (D), and J gene segments
  • required for the maintenance of a normal DNA damage-induced G2/M cell cycle arrest
  • required to cleave DNA hairpins at coding joints during V(D)J recombination, for repair of DSBs by the non homologous end joining pathway, and for cell cycle checkpoint regulation in response to DNA damage
  • involved in V(D)J recombination and nonhomologous end joining (NHEJ) of DNA double-strand break (DSB) repair
  • but only partially participates in the NHEJ pathway to repair DSBs in human somatic cells
  • negative regulator of TP53 in response to oxidative stress in both primary cells and cancer cell lines
  • DNA nuclease that plays important roles in non-homologous end-joining (NHEJ), a major double-strand break (DSB) repair pathway
  • is involved in multiple biological processes through interactions with different binding partners
  • while both SETMAR and DCLRE1C are biochemically capable of resolving a variety of damaged DNA ends for the repair of complex double-strand breaks, DCLRE1C appears to act more efficiently in the context of other nonhomologous end joining proteins
  • is the major downstream effector of the TP53BP1 pathway, which prevents end resection and promotes nonhomologous end-joining and therefore directly competes with the homologous recombination repair pathway
  • DCLRE1C and ERCC4-ERCC1 can also induce stalled DNA replication forks cleavage through non-epistatic pathways all along S and G2 phases of the cell cycle

    PATHWAY
    metabolism
    signaling
    a component
  • forming a key nuclease for nonhomologous DNA end joining (NHEJ) in vertebrate organisms by asssociated with DNA-dependent protein kinase (DNA-PKcs)
  • INTERACTION
    DNA binding
    RNA
    small molecule
    protein
  • interacts with ATM, BRCA1, PRKDC and TP53BP1
  • interacting with known cell cycle checkpoint proteins and being a phosphorylation target of the checkpoint kinase ATM or ATR after exposure of cells to IR or UV irradiation, respectively
  • processing of 3'-phosphoglycolate-terminated DNA double strand breaks
  • interacting with XRCC6 and the DNA-dependent protein kinase catalytic subunit at DNA ends
  • functions as a positive regulator of AMPK signaling by stabilizing the STK11–AMPK complex
  • DCLRE1C physically interacts with PRKAA2
  • promote STK11-mediated phosphorylation and activation of AMPK by stabilizing the STK11–PRKAA2 complex
  • DCLRE1C and LIG4 act cooperatively to promote Nonhomologous end-joining (NHEJ), thereby suppressing homologous recombination (HR) (PMI: 23967291)
  • is a PAXIP1-binding protein
  • Rapid Replication Fork Breakage (RRFB) mediated by DCLRE1C and ERCC4 in response to DNA replication stress (DRS) contributes to DNA replication efficiency and limit chromosomal instability
