XIAP Gene Editing    

XIAP (X-linked inhibitor of apoptosis protein), also known as inhibitor of apoptosis protein 3 (IAP3) and an inhibitor of baculovirus containing protein 4 of the IAP repeat (BIRC4), is one of the important members of the family of apoptosis inhibition. Structurally, XIAP contains three BIRs, an ubiquitin binding (UBA) domain, and a RING finger domain (Figure 1).

XIAP Gene Editing Figure 1: Structural representation of XIAP (Stefanie Galbán. 2010).

The role of XIAP as a potent anti-apoptotic protein has been attributed to its ability to directly bind to and inhibit specific caspase (Figure 2). The BIR3 domain of XIAP binds to the amino terminus of the caspase-9, preventing its dimerization and inhibiting its protease activity. XIAP-mediated inhibition of caspase-3 and -7 is the result of binding to the BIR2 groove, which also requires an amino terminal flanking residue that can compete with proteins containing the IAP binding motif (IBM). Studies have shown that the RING domain is important for heterodimerization with c-IAP1. In addition to its anti-apoptotic properties, XIAP has been implicated in a variety of intracellular signaling events, including the NF-κB, the c-Jun-N-terminal kinase, and the TGF-β, as well as involvement in maintaining intracellular copper stability.

Studies have shown that XIAP disorders can lead to cancers, neurodegenerative diseases, and autoimmune diseases, and a high proportion of XIAP has great potential to act as a tumor marker. Mutations in the XIAP gene cause severe and rare inflammatory bowel disease, and loss of XIAP leads to X-linked lymphoproliferative disorders.
