BIRC2 (baculoviral IAP repeat containing 2) is a member of the inhibitor of apoptosis protein (IAP) family. It is expressed almost exclusively in nucleus, which is mediated by its Bir domains. BIRC2 is a RING finger ubiquitin ligase (E3). This gene is localized to chromosome 11q22.
Synonyms: Anti-Baculoviral IAP repeat-containing protein 2; Anti-C-IAP1; Anti-HIAP-2; Anti-HIAP2; Anti-IAP homolog B; Anti-Inhibitor of apoptosis protein 2; Anti-RING finger protein 48; Anti-TNFR2-TRAF-signaling complex protein 2

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: Baculoviral IAP repeat containing 2 (BIRC2) is responsible for regulating NF-?B signaling, as well as apoptosis. It normally exists as a monomer, but is induced by proapoptotic signals to dimerize and undergo proteasomal degradation. It acts as an inhibitor of caspase, as well as a co-factor in tumor necrosis factor signaling. Studies suggest that, BIRC2 might regulate cell cycle, as it is accumulated in the midbody of cells in telophase stage. BIRC2 has also been proposed as an oncogene, as it degrades Mad-1, which is an antagonist of Myc. Degradation of Mad-1 leads to increased levels of Myc, which in turn promotes cell proliferation. It also regulates E2F1 transcription factor, and prevents its binding to DNA and E2F1-mediated transcriptional activation. BIRC2 is overexpressed in uterine cervix carcinoma of squamous cell type.
