Quizplus · Accepted Answer

Calmodulin is a well-known intracellular calcium-binding protein that plays a key role in many cellular processes, including muscle contraction, enzyme regulation, and neurotransmitter release. It binds calcium ions through EF-hand motifs and undergoes conformational changes that enable it to interact with a wide range of target proteins.
