ID:CFLAR_HUMAN DESCRIPTION: RecName: Full=CASP8 and FADD-like apoptosis regulator; AltName: Full=Caspase homolog; Short=CASH; AltName: Full=Caspase-eight-related protein; Short=Casper; AltName: Full=Caspase-like apoptosis regulatory protein; Short=CLARP; AltName: Full=Cellular FLICE-like inhibitory protein; Short=c-FLIP; AltName: Full=FADD-like antiapoptotic molecule 1; Short=FLAME-1; AltName: Full=Inhibitor of FLICE; Short=I-FLICE; AltName: Full=MACH-related inducer of toxicity; Short=MRIT; AltName: Full=Usurpin; Contains: RecName: Full=CASP8 and FADD-like apoptosis regulator subunit p43; Contains: RecName: Full=CASP8 and FADD-like apoptosis regulator subunit p12; Flags: Precursor; FUNCTION: Apoptosis regulator protein which may function as a crucial link between cell survival and cell death pathways in mammalian cells. Acts as an inhibitor of TNFRSF6 mediated apoptosis. A proteolytic fragment (p43) is likely retained in the death-inducing signaling complex (DISC) thereby blocking further recruitment and processing of caspase-8 at the complex. Full length and shorter isoforms have been shown either to induce apoptosis or to reduce TNFRSF-triggered apoptosis. Lacks enzymatic (caspase) activity. SUBUNIT: TNFRSF6 stimulation triggers recruitment to the death- inducing signaling complex (DISC) formed by TNFRSF6, FADD and caspase-8. A proteolytic fragment (p43) stays associated with the DISC. Also interacts with caspase-10, caspase-3, TRAF1, TRAF2 and Bcl-X(L) (in vitro). Interacts with HBV protein X. TISSUE SPECIFICITY: Widely expressed. Higher expression in skeletal muscle, pancreas, heart, kidney, placenta, and peripheral blood leukocytes. Also detected in diverse cell lines. Isoform 8 is predominantly expressed in testis and skeletal muscle. INDUCTION: Repressed by IL2/interleukin-2 after TCR stimulation, during progression to the S phase of the cell cycle. DOMAIN: The caspase domain lacks the active sites residues involved in catalysis. PTM: Proteolytically processed; probably by caspase-8. Processing likely occurs at the DISC and generates subunit p43 and p12. SIMILARITY: Belongs to the peptidase C14A family. SIMILARITY: Contains 2 DED (death effector) domains.

The RNAfold program from the Vienna RNA Package is used to perform the secondary structure predictions and folding calculations. The estimated folding energy is in kcal/mol. The more negative the energy, the more secondary structure the RNA is likely to have.

The pictures above may be empty if there is no ModBase structure for the protein. The ModBase structure frequently covers just a fragment of the protein. You may be asked to log onto ModBase the first time you click on the pictures. It is simplest after logging in to just click on the picture again to get to the specific info on that model.
Orthologous Genes in Other Species
Orthologies between human, mouse, and rat are computed by taking the best BLASTP hit, and filtering out non-syntenic hits. For more distant species reciprocal-best BLASTP hits are used. Note that the absence of an ortholog in the table below may reflect incomplete annotations in the other species rather than a true absence of the orthologous gene.
