Tropomyosin 1 / TRP channels

Name: Tropomyosin alpha-1 chain (Tropomyosin 1)
Official Symbol: TPM1 provided by HGNC
Function:
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.
