synthetic peptide corresponding to amino acids 2-18 of the N-terminal region of FLICE-inhibitory protein (FLIP). This sequence is identical in all FLIP splice variants.

General description

In human Viral FLICE-inhibitory proteins (v-FLIPs) is identified as c-FLIP. It is composed of two death effector domains which have structural resemblance with the N-terminal half of caspase-8 and a caspase-like domain. It exist as multiple splice variants: FLIP α, β, γ and δ. Along with splice variants, it has two endogenous forms of the protein c-FLIPlong and c-FLIPshort.

Physical form

Solution in phosphate buffered saline containing 0.02% sodium azide.


Detects all FLIP splice variants including FLIPα (FLIPL), FLIPβ, FLIPγ, and FLIPδ (FLIPS) by immunoblotting.


Anti-FLIPL C-Terminal antibody is suitable for immunoblots assay to study the expression levels of elevated c-FLIP protein expression levels in rat carotid arteries five days post-balloon injury. It is also suitable for western blot at a concentration of 0.5-1μg/mL.

Biochem/physiol Actions

C-FLIP plays an important role in apoptosis signaling pathways. It acts as proapoptotic molecule or as an anti-apoptotic molecule. It has been reported that c-FLIP can interact with both FADD and caspase-8. It prevents caspase-8 recruitment and processing through DED-DED interaction followed by CD95-induced apoptosis.
