TPM1 Protein, Human (His)

TPM1 encodes tropomyosin, a key actin-binding component in muscle contraction and cytoskeletal structure. It contains α-helical chains that form a coiled-coil structure that stabilizes actin filaments. TPM1 Protein, Human (His) is the recombinant human-derived TPM1 protein, expressed by E. coli , with N-His labeled tag. The total length of TPM1 Protein, Human (His) is 284 a.a., with molecular weight of ~35 kDa.

TPM1 Protein, a member of the tropomyosin family, belongs to a highly conserved group of actin-binding proteins crucial for the contractile system in striated and smooth muscles, as well as the cytoskeleton of non-muscle cells. Comprising two alpha-helical chains arranged as a coiled-coil, tropomyosin polymerizes along the grooves of actin filaments, providing structural stability. This protein, a key alpha helical chain, serves as the predominant tropomyosin in striated muscle, where it collaborates with the troponin complex to regulate the calcium-dependent interaction between actin and myosin during muscle contraction. In smooth muscle and non-muscle cells, alternative splicing yields various isoforms. Mutations in the TPM1 gene are associated with type 3 familial hypertrophic cardiomyopathy and dilated cardiomyopathy 1Y. Moreover, TPM1 displays biased expression, with notable levels observed in the heart and prostate, along with nine other tissues, underscoring its importance in diverse physiological contexts.

Lyophilized powder

Lyophilized from a 0.2 μm filtered solution of PBS, 10% Glycerol, pH 7.4.

<1 EU/μg, determined by LAL method.

It is not recommended to reconstitute to a concentration less than 100 μg/mL in ddH₂O. For long term storage it is recommended to add a carrier protein (0.1% BSA, 5% HSA, 10% FBS or 5% Trehalose).

Stored at -20°C for 2 years. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer (with carrier protein). It is recommended to freeze aliquots at -20°C or -80°C for extended storage.

Room temperature in continental US; may vary elsewhere.
