A protein called BAG3 acts like a magnet to grab another protein called TSC1, and together they help move a team of proteins to special cable-like structures in cells when those cells are stretched or pulled.

When muscles are stretched or strained, a protein called BAG3 grabs onto another protein called TSC1 and pulls the whole team (TSC1/TSC2) to the muscle’s structural ropes (actin stress fibers) to help clean up damage — exactly what the claim says.

Similar Assertions

When cells are stretched or pushed, a protein called BAG3 grabs onto two other proteins (TSC1/TSC2) that normally slow down protein production. This lets the cell make more proteins, as if it’s hitting the gas pedal.
