      Translesion synthesis by REV1, organism-specific biosystemREV1 (hREV1) encodes a template-dependent dCMP transferase that can insert a C residue opposite an abasic site (Lin et al. 1999, Gibbs et al. 2000). Interaction with monoubiquitinated PCNA at a DNA d...
    • Translesion synthesis by Y family DNA polymerases bypasses lesions on DNA template, organism-specific biosystem (from REACTOME)
      Translesion synthesis by Y family DNA polymerases bypasses lesions on DNA template, organism-specific biosystemUbiquitous environmental and endogenous genotoxic agents cause DNA lesions that can interfere with normal DNA metabolism including DNA replication, eventually resulting in mutations that lead to carc...

    RefSeqs maintained independently of Annotated Genomes

    These reference sequences exist independently of genome builds. Explain

    These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
