Here we report further data showing the presence of the BAG3 receptor (Interferon‐induced transmembrane protein [IFITM]‐2) on the plasma membrane of normal dermal fibroblasts and the activity of BAG3 as a factor able to induce the expression of α‐smooth muscle actin and the phosphorylation of AKT and focal adhesion kinase, that sustain CAF functions in tumor microenvironment. This evidence concerns the gene BAG3 and neoplasm.
