Article Synopsis
  • A mutation in mice (p100H/p100H) linked to cardioskeletal myopathy and early death disrupts the Sox6 gene, which is important for heart muscle development.
  • In an experimental setup, Sox6 was found to be crucial for differentiating cells into beating cardiac myocytes, and interacts with the protein Prtb.
  • BMP signaling is necessary for Sox6 expression during this cell differentiation, and both Sox6 and Prtb affect the expression of a key calcium channel involved in heart function.
