Myosin Light Chain
Myosin Light Chain (MLC) is a protein that plays a crucial role in muscle contraction. It is part of the myosin motor protein complex, which interacts with actin filaments to facilitate movement. MLC exists in different forms, including regulatory and essential light chains, and its phosphorylation is essential for activating myosin's motor function.
In addition to muscle cells, MLC is also found in non-muscle cells, where it contributes to various cellular processes, such as cell division and motility. The regulation of MLC is vital for maintaining proper cellular function and responding to external signals, highlighting its importance in both muscle and non-muscle tissues.
