Figure 1 Enhancing Muscle Performance by Restricting MLN
In normal muscle cells (left), MLN (dark red) binds to SERCA (blue) in the membrane of the sarcoplasmic reticulum (SR) and restricts the import of calcium. In reduced MLN (right), SERCA pump activity is liberated to keep calcium high in the SR lumen, resulting in higher calcium availability and increased export by ryanodine receptors (orange) to increase contraction of working muscle cells and improve performance.
