What Does HMM Stand For?

HMM stands for Heavy Meromyosin

HMM, or Heavy Meromyosin, is a subfragment of the myosin protein that plays a crucial role in muscle contraction. It is derived from the myosin molecule through proteolytic cleavage and is composed of the heavy chain portion, which is responsible for interaction with actin filaments. HMM is characterized by its ATPase activity and ability to generate force and movement in muscle cells, making it essential for understanding muscle physiology and mechanics. Its study is significant in both basic biology and clinical research related to muscle disorders.
