a Subcellular fractionation assay for the MM2P location in RAW264.7 cells. b Pulldown assay was performed to verify the enrichment of STAT3 protein in the products pulled down by the MM2P biotin probe compared with the non-biotin probe. c RIP analysis confirmed the interaction between MM2P and STAT3. d FISH stain of MM2P and IF stain of STAT3 in M2 macrophages. Scale bar = 20 μm. e MM2P-pulldown assay for STAT3 enrichment after transfecting Flag-tagged STAT3 into IL-13/IL-4-induced M2 macrophages. f RIP analysis was used to detect the interaction between STAT3 and MM2P after adding S31–201 with indicated dose, the inhibitor of STAT3. g Co-IP assay was carried out in IL-13/IL-4-induced M2 macrophages to identify the binding of SHP2 or SHP1 with STAT3 after silencing MM2P. **P < 0.01. The error bar expressed as mean ± SD of three independent experiments in triplicates.
