ID:PARP2_HUMAN DESCRIPTION: RecName: Full=Poly [ADP-ribose] polymerase 2; Short=PARP-2; Short=hPARP-2; EC=2.4.2.30; AltName: Full=ADP-ribosyltransferase diphtheria toxin-like 2; Short=ARTD2; AltName: Full=NAD(+) ADP-ribosyltransferase 2; Short=ADPRT-2; AltName: Full=Poly[ADP-ribose] synthase 2; Short=pADPRT-2; 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 LRIG3. Homo- and heterodimer with PARP1. SUBCELLULAR LOCATION: Nucleus. TISSUE SPECIFICITY: Widely expressed, mainly in actively dividing tissues. The highest levels are in the brain, heart, pancreas, skeletal muscle and testis; also detected in kidney, liver, lung, placenta, ovary and spleen; levels are low in leukocytes, colon, small intestine, prostate and thymus. PTM: Poly-ADP-ribosylated by PARP1 (By similarity). SIMILARITY: Contains 1 PARP alpha-helical domain. SIMILARITY: Contains 1 PARP catalytic domain. SEQUENCE CAUTION: Sequence=AAD29857.1; Type=Erroneous initiation; Sequence=AAL77437.1; Type=Erroneous gene model prediction; Sequence=CAB41505.2; Type=Erroneous initiation; WEB RESOURCE: Name=NIEHS-SNPs; URL="http://egp.gs.washington.edu/data/adprtl2/";
The RNAfold program from the Vienna RNA Package is used to perform the secondary structure predictions and folding calculations. The estimated folding energy is in kcal/mol. The more negative the energy, the more secondary structure the RNA is likely to have.

The pictures above may be empty if there is no ModBase structure for the protein. The ModBase structure frequently covers just a fragment of the protein. You may be asked to log onto ModBase the first time you click on the pictures. It is simplest after logging in to just click on the picture again to get to the specific info on that model.
Orthologous Genes in Other Species
Orthologies between human, mouse, and rat are computed by taking the best BLASTP hit, and filtering out non-syntenic hits. For more distant species reciprocal-best BLASTP hits are used. Note that the absence of an ortholog in the table below may reflect incomplete annotations in the other species rather than a true absence of the orthologous gene.
