Biological Activity for CST 905

CST 905 is a potent and selective BRAFV600E Degrader (PROTAC®) (DC50 = 18 nM). CST 905 comprises a ligand for the von Hippel Lindau (VHL) E3 ligase joined by a linker to a PLX-derived ligand. Unlike other BRAFV600E Degraders, CST 905 does not activate ERK.

B-Raf antibody validated for Simple Western™ (automated Western) instruments and Western Blot also available: Catalog # AF3424.

RAS Oncoproteins Scientific Review

Written by Kirsten L. Bryant, Adrienne D. Cox and Channing J. Der, this review provides a comprehensive overview of RAS protein function and RAS mutations in cancer. Key signaling pathways are highlighted and therapeutic vulnerabilities are explored. This review also includes a detailed section on RAS drug discovery and targeting synthetic lethal interactors of mutant RAS. Compounds available from Tocris are listed.

Targeted Protein Degradation Poster

Targeted Protein Degradation Poster

Degraders (e.g. PROTACs) are bifunctional small molecules, that harness the Ubiquitin Proteasome System (UPS) to selectively degrade target proteins within cells. They consist of three covalently linked components: an E3 ubiquitin ligase ligand, a linker and a ligand for the target protein of interest. Authored in-house, this poster outlines the generation of a toolbox of building blocks for the development of Degraders. The characteristics and selection of each of these components are discussed.
