TPM3

Tropomyosin alpha-3 chain;Isoform 6 of Tropomyosin alpha-3 chain;Isoform 2 of Tropomyosin alpha-3 chain;Isoform 3 of Tropomyosin alpha-3 chain

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