Recombinant SRCR1-4 protein directly interacts with MYH9 in PAMs. (A) PAMs were incubated with SRCR1-4 or the same quantity of BSA. Cells were subjected to immunofluorescence staining of MYH9 (red) and SRCR1-4 (green) and cellular nuclei were counterstained with DAPI (blue). Co-localization of MYH9 and SRCR1-4 was visualized by confocal microscopy. (B) The membrane fraction of SRCR1-4 or BSA-preincubated PAMs was extracted using the Membrane Protein Extraction Kit followed by Western blot analysis to detect MYH9 expression. (C) PAMs were pre-incubated with SRCR1-4 or BSA. Cytoplasmic and membrane fractions were separated using a Membrane Protein Extraction Kit and then each fraction was immunoprecipitated with anti-MYH9 pAb to detect the interaction between MYH9 and recombinant SRCR1-4 protein.
