PARP4 (Poly ADP-ribose polymerase family, member 4) is a 193kDa nuclear, NAD-dependent, vault protein encoding an ADP-ribosyltransferase-like protein. It is a subunit of ribonucleoprotein (RNP) complex belonging to the inter-a-inhibitor family. Structurally, it is composed of a catalytic domain similar to the nuclear-localized ADP-ribosyltransferase proteins (Adprt), two Adprt-like proteins (Adprtl2 and Adprtl3), and the telomere-associated protein tankyrase.
Synonyms: Anti-193 kDa vault protein; Anti-PARP-4; Anti-PH5P; Anti-Poly recombinant protein; Anti-VPARP; Anti-Vault poly(ADP-ribose
Storage: -20C
Application: All Prestige Antibodies Powered by Atlas Antibodies are developed and validated by the Human Protein Atlas (HPA) project (www.proteinatlas.org)and as a result, are supported by the most extensive characterization in the industry. The Human Protein Atlas project can be subdivided into three efforts: Human Tissue Atlas, Cancer Atlas, and Human Cell Atlas. The antibodies that have been generated in support of the Tissue and Cancer Atlas projects have been tested by immunohistochemistry against hundreds of normal and disease tissues and through the recent efforts of the Human Cell Atlas project, many have been characterized by immunofluorescence to map the human proteome not only at the tissue level but now at the subcellular level. These images and the collection of this vast data set can be viewed on the Human Protein Atlas (HPA) site by clicking on the Image Gallery link.

Biochem Physiol Actions: PARP4 (Poly ADP-ribose polymerase family, member 4) is associated with various cellular processes including genomic DNA integrity related activities, DNA repair, replication, transcription, and apoptosis. In DNA assembly, it crucially identifies the DNA nick sites and rejoins the DNA strands. It poly(ADP-ribosyl)ates the nuclear proteins in response to any DNA damage.
