BIRC2 Background

Baculoviral inhibitors of apoptosis repeat-containing protein 2 (BIRC2), also called cellular inhibitors of apoptosis 1 (cIAP1), is a protein in humans that is encoded by BIRC2 gene [1][2]. cIAP1 contains three tandem amino-terminal BIR domains, a zinc-binding RING domain at the carboxy terminus, and a caspase-recruitment (CARD) domain in the linker region between the BIR and the RING (Really Interesting New Gene) domains [3]. Among the domains of cIAP1, the RING domain exerts an important role in preventing apoptosis. This domain acts as an E3 ligase by binding to E2 ubiquitin-conjugating enzymes (UBCs) and catalyzing the transfer of ubiquitin onto target proteins [7] such as caspases, ultimately inhibiting apoptosis [3][4]. The CARD domain of cIAP1 is reported to emit a functional nuclear export signal that seems to be important for cell differentiation [12]. BIRC2 protein also mediates various cellular functions, including the regulation of signaling and inflammation [5]. Rothe M et al. have uncovered that BIRC2 and another IAP family member BIRC3, together with TRAF2, are key components of the TNF signaling pathway that are necessary for TNF-mediated NF-kappa B activation [6][7][8]. On the contrary, BIRC2, and BIRC3 act as a molecular brake to rein inactivation of the JNK signaling pathway [9]. The amplification and increased levels of cIAP1 have been observed in several cancer types and are required for tumorigenesis in vivo [10]. cIAP1 deprivation, caused by IAP antagonist drugs or cIAP1 deletion, might augment physiological TNF-receptor apoptotic signaling, thus resulting in enhanced tumor cell death [11]. It suggests a promising cancer treatment by using some IAP antagonist compounds [12].
