APEX1 (apurinic/apyrimidinic endodeoxyribonuclease 1) is a multifunctional DNA base excision repair (BER) protein, associated with various cellular functions including oxidative signaling, transcription factor regulation and cell cycle control.
Synonyms: Anti-AP endonuclease 1 antibody produced in rabbit; Anti-APEN antibody produced in rabbit; Anti-APEX nuclease antibody produced in rabbit; Anti-DNA-(apurinic or apyrimidinic site) lyase antibody produced in rabbit; Anti-REF-1 protein antibody produced in rabbit

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: APEX1 (apurinic/apyrimidinic endodeoxyribonuclease 1) performs an essential role in the DNA BER (base excision repair) pathway. It acts on the damaged bases caused by endogenous and exogenous agents. It accelerates the cleaving of 5' end, an abasic site in duplex DNA, through Mg2+-dependent manner. It stimulates the DNA-binding activity of transcription factors such as Fos-Jun, nuclear factor-?B, Myb, HLF, PAX, and p53. It is also involved in the apoptosis associated with thioredoxin. It is upregulated in various cancer cells, such as germ cell tumors (GCTs) in testicular cancer. It acts as a 'hub-protein' that controls pathways essential for the cell survival, such as energy metabolism, cytoskeletal elements and stress-dependent responses.
