TPM4 encodes a member of the tropomyosin family of actin-binding proteins involved in the contractile system of striated and smooth muscles and the cytoskeleton of non-muscle cells. Additionally we are shipping Tropomyosin 4 Antibodies (45) and Tropomyosin 4 Proteins (14) and many more products for this protein.

Human TPM4 ELISA Kit for Sandwich ELISA - ABIN854376
Ortea, Roschitzki, López-Rodríguez, Tomero, Ovalles, López-Longo, de la Torre, González-Alvaro, Gómez-Reino, González: Independent Candidate Serum Protein Biomarkers of Response to Adalimumab and to Infliximab in Rheumatoid Arthritis: An Exploratory Study. in PLoS ONE 2016
Results show that Tpm4.2 facilitates the transition of NM-2A to the strongly actin-binding myosin-ADP state.
In addition to CLIC1 (show CLIC1 ELISA Kits) and TPM1 (show TPM1 ELISA Kits), which were the proteins initially discovered in a xenograft mouse model, CLIC4 (show CLIC4 ELISA Kits), TPM2 (show TPM2 ELISA Kits), TPM3 (show TPM3 ELISA Kits), and TPM4 were present in ovarian cancer patient sera at significantly elevated levels compared with controls.
Data indicate the upregulation of tropomyosin-4 in infiltrating ductal breast carcinomas (IDCAs) tissues, which may suggest its involvement in breast cancer development.
Plasma peroxiredoxins 1 and 2, and tropomyosin 4 were shown to associate with asbestos-exposure, and peroxiredoxin 1 (show PRDX1 ELISA Kits) with lung cancer.
TPM4, PDIA and SRC8 were also localized to the trophoblast cells, further highlighting the importance of these cytoskeletal remodelling proteins in early pregnancy
Low TPM4 expression in the cytoplasm is associated with uterine cervix carcinogenesis.
Tm4-defined cytoskeleton is a marker of growth and repair/regeneration in response to injury, disease state and stress in skeletal muscle.
Tm-4 is specifically enriched within and around osteoclast attachment structures, the sealing zone and podosomes.
Tropomyosin 4 defines longitudinal filaments in mouse models of muscular dystrophy and nemaline myopathy.
These results indicate that Tm-4 plays a role in regulating adhesion structures of osteoclasts, most likely by stabilizing the actin microfilaments present in podosomes and the sealing zone.
upregulation of tropomyosin 4 (TM4) mRNA is a relevant marker of dedifferentiation in vascular smooth muscle cells.
This gene encodes a member of the tropomyosin family of actin-binding proteins involved in the contractile system of striated and smooth muscles and the cytoskeleton of non-muscle cells. Tropomyosins are dimers of coiled-coil proteins that polymerize end-to-end along the major groove in most actin filaments. They provide stability to the filaments and regulate access of other actin-binding proteins. In muscle cells, they regulate muscle contraction by controlling the binding of myosin heads to the actin filament. Multiple transcript variants encoding different isoforms have been found for this gene.
