摘要

Synthesized a S1R-selective affinity-resin using the small molecule ligand, reduced haloperidol. Quantitatively isolated S1R from an in vitro cell line under optimized conditions. Identified 23 potential interacting partners of S1R by quantitative proteomics comparison and statistical analysis. Validated the interaction between S1R and calnexin, the 26S proteasome, and the 80S ribosome. Proposed a model for the protective role of S1R in shielding cancer cells from ER stress-induced apoptosis.
