Supplementary information

Tropomyosin 1 (alpha) also known as alpha-tropomyosin is a protein widely expressed in skeletal and cardiac muscle tissues. This protein plays a central role in muscle contraction by binding to actin filaments. Its precise molecular weight is approximately 32.7 kDa. Alpha-tropomyosin stabilizes actin filaments and regulates the interaction of actin with myosin which is essential for muscular contraction.
Biological function summary

Alpha-tropomyosin ensures the regulation of actin-myosin interactions during muscle contraction. It forms part of the troponin-tropomyosin complex which includes other key proteins such as troponin I T and C. This complex undergoes conformational changes in response to calcium ion concentrations allowing muscle contraction to occur. Alterations in this complex can significantly affect muscle function highlighting the central role of alpha-tropomyosin.

Pathways

Alpha-tropomyosin operates within the actin cytoskeleton regulatory pathway and the calcium signaling pathway. It is closely related to the troponin complex proteins facilitating muscle contraction in these pathways by controlling actin and myosin interactions. Calcium ions bind to troponin C causing structural changes that shift tropomyosin on the actin filament therefore enabling the binding of myosin heads to actin.

Mutations or dysregulation of alpha-tropomyosin have been linked to conditions like hypertrophic cardiomyopathy and nemaline myopathy. These disorders often result from altered interactions within the troponin-tropomyosin complex and other proteins like myosin heavy chain. Defective regulation of these interactions impairs muscle contraction leading to the clinical manifestations seen in these diseases.

Target data

Binds to actin filaments in muscle and non-muscle cells (PubMed : 23170982). Plays a central role, in association with the troponin complex, in the calcium dependent regulation of vertebrate striated muscle contraction (PubMed : 23170982). Smooth muscle contraction is regulated by interaction with caldesmon. In non-muscle cells is implicated in stabilizing cytoskeleton actin filaments.
