In particular, STARS is shown to act as an intermediary between alterations in the cytoskeleton and the activation of serum response factor (SRF)–dependent transcription, thereby influencing muscle cell differentiation, adaptation, and stress-response mechanisms."}, {"type": "fg", "children": [{"type": "fg_f", "ref": "1"}]}, {"type": "t", "text": "\n"}]}, {"type": "t", "text": "\n\n"}, {"type": "p", "children": [{"type": "t", "text": "\nThe studies underline that STARS promotes actin polymerization and activates Rho GTPase signaling cascades, which in turn facilitate the nuclear translocation of myocardin-related transcription factors and enhance the transcriptional activity of SRF.
