TPM3 is a member of the tropomyosin family that binds actin filaments in muscle and nonmuscle cells. In striated muscle, it regulates calcium-dependent contraction together with the troponin complex. TPM3 Protein, Human is the recombinant human-derived TPM3 protein, expressed by E. coli , with tag free. The total length of TPM3 Protein, Human is 248 a.a., with molecular weight of ~20.0 kDa.

Human

The TPM3 protein, a member of the tropomyosin family, exhibits versatile functions in binding to actin filaments both in muscle and non-muscle cells. In conjunction with the troponin complex, TPM3 plays a central role in the calcium-dependent regulation of striated muscle contraction in vertebrates. Its involvement in smooth muscle contraction is mediated through interaction with caldesmon. Beyond muscle-related functions, TPM3 is implicated in stabilizing actin filaments within the cytoskeleton of non-muscle cells. Structurally, TPM3 forms homodimers and heterodimers, combining with alpha (TPM1, TPM3, or TPM4) and beta (TPM2) chains. Additionally, TPM3 interacts with TMOD1, further contributing to its multifaceted role in modulating actin dynamics across various cellular contexts.
