Calmodulin is Involved in the Regulation Of

Question

Calmodulin is involved in the regulation of:
A)skeletal muscle contraction.
B)propagation of a nerve impulse across a synapse.
C)contraction of smooth muscle.
D)propagation of heart muscle contraction to the entire myocardium.

Accepted Answer

Calmodulin is a calcium-binding messenger protein expressed in all eukaryotic cells, playing a pivotal role in the calcium signaling pathway. It is particularly involved in the regulation of smooth muscle contraction by activating myosin light-chain kinase, which in turn phosphorylates myosin, leading to muscle contraction.
