RBPMS mediates smooth muscle specific alternative splicing via oligomerization and modulation of trans splicing factor recruitment

RBPMS regulates alternative splicing decision via recruiting other trans factors. This experiment aims to investigate the interactome of Strep-II tagged recombinant RBPMS in Hela nuclear extract. The interactome of the full length protein is compared to the construct lacking the far C-terminal 20 amino acids. The “R” series indicates full-length RBPMS pull-down. The “P” series indicates truncated RBPMS pull-down. The “BL” series indicates full length RBPMS pull-down in the absence of nuclear extract input but with bovine serum albumin beads blocking reagent. The “N” series indicates non-baited negative control pull-down.
