Xin is a novel actin binding protein that regulates satellite cell function

We previously identified Xin, a novel actin binding protein, to be upregulated during the early phases of skeletal muscle regeneration. Here we demonstrate the transcriptional regulation of Xin within skeletal muscle and assess its function within satellite cell progeny (myoblasts). To define transcriptional regulation, promoter‐reporter assays were performed in the presence of known myogenic transcription factors (MEF2, MyoD and Myf‐5). All …
