The transcription factor SRF, together with its co-factors MRTF-A and MRTF-B, controls cytoskeletal gene expression. Here authors show that MRTF/SRF inactivation leads to decreased IL-2 mediated CD8 + T cell proliferation during infection, resulting from disrupted homotypic cell clustering and reduced retention of IL-2.
