Polyclonal antibody to FLIP
Fig:1 Immunhohistochemical analysis of FLIP in two tissues cores from a formalin-fixed, paraffin-embedded human brain tumor microarray using 20-1065 at 1:2000. A, gemistocytoma (Grade II) positive for FLIP expression. B, gemistocytoma (Grade II) negative for FLIP expression. A1 and A2 are higher magnifications from A. A, A1, and A2 show expression of FLIP in the gemistocytes of the tumor. Hematoxylin-eosin counterstain.

This antibody recognizes FLIP long and short, isoforms that contain the peptide immunogen sequence (DRKAVETHLLRNPHLVSD). Human FLIP is a 480 amino acid protein which contains two death effector domains (DEDs) and a caspase-like domain. FLIP interacts with adapter protein FADD and caspase-8 and 10, and potently inhibits apoptosis induced by death receptors.However, the functions of FLIP remain to be fully elucidated and there is some evidence FLIP may also act as an activator of caspase-8/-10 in certain cases, thereby taking on an apoptosis promoting role.Cell death signals are transduced by death domain (DD)- containing adapter molecules and members of the caspase (ICE/CED-3) protease family. Most if not all, forms of apoptosis involve activation of the caspases. Caspases-8 (FLICE) and -10 (FLICE2) are two pivotal members in the caspase family. FLICE-inhibitory proteins were identified in virus and human and designated v-FLIPs and FLIP, respectively. The human FLIP was also cloned by several labs independently and termed Casper , I-FLICE, FLAME-1, CASH and CLARP3-7.

For Research Use Only. Not for use in diagnostic/therapeutics procedures.
| Post transnational modification: | Proteolytically processed; probably by caspase-8. Processing likely occurs at the DISC and generates subunit p43 and p12. |
| 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. |
| BioGrid: | 114364. 40 interactions. |
