The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
1/500 - 1/1000. Detects a band of approximately 55 kDa (predicted molecular weight: 55 kDa).
Use at an assay dependent dilution.
FunctionApoptosis 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.
Tissue specificityWidely 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.
Sequence similaritiesBelongs to the peptidase C14A family. Contains 2 DED (death effector) domains.
DomainThe caspase domain lacks the active sites residues involved in catalysis.
Post-translational modificationsProteolytically processed; probably by caspase-8. Processing likely occurs at the DISC and generates subunit p43 and p12.
