Transverse tubules are extensions of the cell membrane that penetrate into the centre of skeletal and cardiac muscle cells. With membranes that contain large concentrations of ion channels, transporters, and pumps, T-tubules permit rapid transmission of the action potential into the cell, and also play an important role in regulating cellular calcium concentration. Through these mechanisms, T-tubules allow heart muscle cells to contract more forcefully by synchronising calcium release throughout
Tubulin (tubul- + -in) in molecular biology can refer either to the tubulin protein superfamily of globular proteins, or one of the member proteins of that superfamily.o form microtubules, the dimers of Î±- and Î²-tubulin bind to GTP and assemble onto the (+) ends of microtubules while in the GTP-bound state.
