This gene is a member of the tropomyosin family of highly conserved, widely distributed actin-binding proteins involved in the contractile system of striated and smooth muscles and the cytoskeleton of non-muscle cells. Tropomyosin is composed of two alpha-helical chains arranged as a coiled-coil. It is polymerized end to end along the two grooves of actin filaments and provides stability to the filaments. The encoded protein is one type of alpha helical chain that forms the predominant tropomyosin of striated muscle, where it also functions in association with the troponin complex to regulate the calcium-dependent interaction of actin and myosin during muscle contraction. In smooth muscle and non-muscle cells, alternatively spliced transcript variants encoding a range of isoforms have been described. Mutations in this gene are associated with type 3 familial hypertrophic cardiomyopathy and dilated cardiomyopathy 1Y. [provided by RefSeq, Jun 2022]
A review of proteomics in forensic science notes that the TPM1 is a protein marker for post-mortem interval (PMI) estimation in early PMI from skeletal muscle in humans and animal models, where its abundance decreases post-mortem [Alex et al. DOI:10.1016/j.scijus.2025.101320]. A study in mice demonstrated that the TPM1 is a tissue-specific target and the most expressed gene in mouse femoral quadriceps and cardiac muscle [Scrivano et al. DOI:10.1007/s00414-019-02125-x]. In a separate investigation using a heart-specific double knockout mouse model, immunoblotting revealed the TPM1 protein level was unchanged in the genetically modified hearts [Lee et al. DOI:10.1093/hmg/ddac108].
