Activity summary

ACTC1 also known as cardiac alpha actin is a protein that plays an essential role in the cytoskeletal structure of heart muscle cells. Weighing around 42 kDa ACTC1 is found predominantly in cardiac tissue specifically in the sarcomere which is the fundamental unit of muscle contraction. In muscle cells ACTC1 organizes into thin filaments and is critical for maintaining the structural integrity and contractile function of the cardiac tissue.

Biological function summary

ACTC1 is significant in muscle contraction and cellular movement and it forms part of the sarcomeric complex within cardiac muscle cells. This protein along with other actin isoforms contributes to the organized network of actin and myosin filaments which generate force for heartbeats. ACTC1 polymerizes to form the actin filament which when coupled with myosin motors and regulatory proteins executes the contraction cycle in cardiac muscles.

Pathways

ACTC1 plays a central role within the muscle contraction process and the cardiac muscle contraction pathway. In these pathways its interaction with proteins like myosin tropomyosin and troponin is vital to initiate and regulate cardiac contractions. The dynamic interaction between ACTC1 and these proteins facilitates the conversion of chemical energy into mechanical energy necessary for the rhythmic contraction and relaxation of heart muscles.

Associated diseases and disorders

Mutations or alterations in ACTC1 are closely linked to cardiac conditions such as hypertrophic cardiomyopathy and dilated cardiomyopathy. These disorders often involve associated proteins like troponin T and myosin heavy chain which when mutated along with ACTC1 disrupt normal cardiac contraction and lead to structural heart changes. These conditions highlight the importance of ACTC1 in maintaining normal cardiac function and structure.
