Protein
Tropomyosin alpha-4 chain
Organism
Rattus norvegicus
Function
Binds to actin filaments in muscle and non-muscle cells (PubMed:7568216). Plays a central role, in association with the troponin complex, in the calcium dependent regulation of vertebrate striated muscle contraction (By similarity). Smooth muscle contraction is regulated by interaction with caldesmon (By similarity). In non-muscle cells is implicated in stabilizing cytoskeleton actin filaments (By similarity). Binds calcium (By similarity).
Similarity
Belongs to the tropomyosin family.
