Background

The tropomyosins are a family of actin filament binding proteins. These proteins were first isolated from skeletal muscle, but later identified in many nonmuscle tissues. Tropomyosins are ubiquitous proteins of 35 to 45 kD associated with the actin filaments of myofibrils and stress fibers. Vertebrates have at least 4 different tropomyosin genes; in humans, they are named TPM1, TPM2, TPM3, and TPM4. Tropomyosins expressed as different isoforms in muscle and non-muscle cells.

Tissue Specificity

TPM1: Detected in primary breast cancer tissues butundetectable in normal breast tissues in Sudanese patients.Isoform 1 is expressed in adult and fetal skeletal muscle andcardiac tissues, with higher expression levels in the cardiactissues. Isoform 10 is expressed in adult and fetal cardiactissues, but not in skeletal muscle.

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.
