CC -!- FUNCTION: Sensor of abasic sites in single-stranded DNA (ssDNA)
CC required to preserve genome integrity by promoting error-free repair of
CC abasic sites. Acts as an enzyme that recognizes and binds abasic sites
CC in ssDNA at replication forks and chemically modifies the lesion by
CC forming a covalent cross-link with DNA: forms a stable thiazolidine
CC linkage between a ring-opened abasic site and the alpha-amino and
CC sulfhydryl substituents of its N-terminal catalytic cysteine residue.
CC The HMCES DNA-protein cross-link is then degraded by the proteasome.
CC Promotes error-free repair of abasic sites by acting as a 'suicide'
CC enzyme that is degraded, thereby protecting abasic sites from
CC translesion synthesis (TLS) polymerases and endonucleases that are
CC error-prone and would generate mutations and double-strand breaks. Has
CC preference for ssDNA, but can also accommodate double-stranded DNA with
CC 3' or 5' overhang (dsDNA), and dsDNA-ssDNA 3' junction.
CC {ECO:0000256|RuleBase:RU364100}.
CC -!- SIMILARITY: Belongs to the SOS response-associated peptidase family.
CC {ECO:0000256|ARBA:ARBA00008136, ECO:0000256|RuleBase:RU364100}.
