Protein FULL name:

poly [ADP-ribose] polymerase 2 [Mus musculus].

Parp2 (Mus musculus) is product of expression of Parp2 gene.

FUNCTION: Involved in the base excision repair (BER) pathway, by catalyzing the poly(ADP-ribosyl)ation of a limited number of acceptor proteins involved in chromatin architecture and in DNA metabolism. This modification follows DNA damages and appears as an obligatory step in a detection/signaling pathway leading to the reparation of DNA strand breaks.

CATALYTIC ACTIVITY: NAD(+) + (ADP-D-ribosyl)(n)-acceptor = nicotinamide + (ADP-D-ribosyl)(n+1)-acceptor.

SUBUNIT: Component of a base excision repair (BER) complex, containing at least XRCC1, PARP1, POLB and LIG3. Homo- and heterodimer with PARP1.


TISSUE SPECIFICITY: Widely expressed; the highest levels were in testis followed by ovary. Expression is correlated with proliferation, with higher levels occurring during early fetal development and organogenesis and in the highly proliferative cell compartments of adult.

DEVELOPMENTAL STAGE: At stage E12.5, expressed at high level in the developing liver and kidneys. At E18.5, preferentially expressed in the thymus and in regions of the nervous system. Within the developing trunk, preferential expression persisted in the liver and became restricted to the cortical region of the kidney, spleen, adrenal gland, and to stomach and intestinal epithelia. From E14.5 to E18.5, as well as in the adult, expressed at the highest level in thymus. Expression is particularly high in the subcapsular zone of the thymus where immature lymphocytes proliferate.

INDUCTION: By high levels of DNA-damaging agents.

PTM: Poly-ADP-ribosylated by PARP1.

PTM: Acetylation reduces DNA binding and enzymatic activity.

SIMILARITY: Contains 1 PARP alpha-helical domain.

SIMILARITY: Contains 1 PARP catalytic domain.

SEQUENCE CAUTION: Sequence=AAC25415.1; Type=Erroneous initiation;

NCBI GenPept GI number(s): 6752992
Species: Mus musculus
