CFLAR Background

CFLAR, short for CASP8 and FADD-like apoptosis regulator, is also known as cellular FLICE--like inhibitory protein (c-FLIP). c-FLIP is expressed constitutively in many cell types, but its lifespan is short because its expression can be regulated by a variety of stimuli [1]. Although many splice variants of c-FLIP have been reported at the mRNA level, only short FLIP (c-FLIPS) and long FLIP (c-FLIPL) could be detected on the protein level as so far [2]. As the mammalian homolog of v-FLIP (virus FLICE-like inhibitory protein), c-FLIP is structurally and sequentially homologous with caspase-8 and caspase-10 that are involved in the initiation of DR (death receptor)-induced apoptosis. c-FLIP consists of two sequential N-terminal DEDs (death effector domain), followed by a C-terminal extension containing a caspase-homologous domain analogous to caspase-8 and caspase-10. Nevertheless, c-FLIP is catalytically inactive because several amino acids conserved in caspases are substituted, such as the cysteine residue within the QACXG-motif and the histidine residue within the HG-motif [3][4]. c-FLIP acts as a dominant-negative inhibitor to hinder apoptosis caused by death-inducing ligands through the binding of the FAS-associated death domain (FADD) protein and/or caspases-8 and caspase-10 at the level of the death-inducing signaling complex (DISC) [5]. Consistently, Yeh WC et al. revealed a protective role for c-FLIP in DR-induced apoptosis of fibroblast cell lines derived from c-FLIP-knockout mice [6]. Since c-FLIP is a major regulator of DR-induced apoptosis, and since the aberrant c-FLIP expression is intertwined with a rising number of pathologies, detecting c-FLIP levels might be valuable to diagnosis, and drugs that only change c-FLIP-expression levels will certainly be a benefit in the treatment of relevant diseases [7].
