Tropomyosin-1/3 (D17B8) Rabbit mAb #3913
Gallery: Tropomyosin-1/3 (D17B8) Rabbit mAb #3913
Tropomyosin-1/3 (D17B8) Rabbit mAb detects endogenous levels of total tropomyosin-1 and/or tropomyosin-3 protein.Species Reactivity: Human, Mouse, Rat
Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Leu274 of human tropomyosin-1 protein.
Tropomyosin-1 (TPM1) belongs to the high molecular weight members of tropomyosin family (1,2). The protein exists in an alpha-helical coiled-coil conformation and binds multiple acting monomers in a tight manner to stabilize and regulate the actin filament (3). Tropomyosins fullfill functions in muscle and non-muscle cells. In muscle cells, tropomyosins associate with the troponin complex and play a central role in the calcium-dependent regulation of striated muscle contraction in vertebrates. In non-muscle cells, tropomyosins are implicated in the formation and stabilization of cytoskeletal actin filaments to ensure normal cellular processes (1,2). Mutations of tropomysin-1 have been reported as a cause of dilated cardiac myopathies (4). Tropomyosin-1 also functions as a tumor suppressor, and many malignant tumors demonstrate downregulation of tropomyosin-1 expression (5-8). Tropomyosin-1 is phosphorylated at Ser283 through the Erk/DAPK pathway, which promotes stress fiber formation in response to oxidative stress (9-10).
