|Epithelial splicing regulatory protein-1 (Esrp-1) and Esrp-2 are mRNA splicing factors that regulate the formation of epithelial cell-specific isoforms. They specifically regulate the expression of FGFR2-IIIb, an epithelial cell-specific isoform of FGFR2, and also regulates the splicing of CD44, CTNND1, ENAH, 3 transcripts that undergo changes in splicing during the epithelial-to-mesenchymal transition (EMT). Esrp-1 and -2 act by directly binding specific sequences in mRNAs. They bind the GU-rich sequence motifs in the ISE/ISS-3, a cis-element regulatory region present in the mRNA of FGFR2.

Anti-Esrp-1/2 antibody by western blot shows detection in 293T cell extracts. Lane 1: GFP-transfected. Lane 2: Esrp-1 transfected (arrow). Lane 3: Esrp-2 transfected. Each lane contains approximately 5 µg of lysate. Primary antibody was used at a 1:1000 dilution in PBS-T plus milk, and reacted for 1hr at room temperature. The membrane was washed and reacted with a 1:10,000 dilution of an anti-mouse ECL antibody for 1hr at room temperature. Molecular weight estimation was made by comparison to prestained MW markers.
