A cDNA clone was sequenced that contains the entire coding region for the muscle tropomyosin II isoform from Drosophila. The cDNA clone is 1253 nucleotides (nt) long and contains an 88-nt 5'-leader sequence and a 310-nt 3'-untranslated sequence. The muscle tropomyosin II isoform consists of 285 amino acids and is 60% homologous with the previously reported muscle tropomyosin I isoform Drosophila and 55% homologous with rabbit muscle tropomyosin.

Background: Hypertrophic cardiomyopathy (HCM) is a frequently encountered cardiac condition worldwide, often inherited, and characterized by intricate phenotypic and genetic manifestations. The natural progression of HCM is diverse, largely due to mutations in the contractile and relaxation proteins of the heart. These mutations disrupt the normal structure and functioning of the heart muscle, particularly affecting genes that encode proteins involved in the contraction and relaxation of cardiac muscle.
View Article and Find Full Text PDFTropomyosin is an actin-binding protein that plays roles ranging from regulating muscle contraction to controlling cytokinesis and cell migration. The simple nematode provides a useful model for studying the core functions of tropomyosin in an animal, having a relatively simple anatomy, and a single tropomyosin gene, , that produces seven isoforms. Three higher molecular weight isoforms (LEV-11A, D, O) regulate contraction of body wall and other muscles, but comparatively less is known of the functions of four lower molecular weight isoforms (LEV-11C, E, T, U).

Emerging evidence suggests that Khib (2-hydroxyisobutyrylation) plays a significant role in the cardiovascular system. Histone deacetylase 3 (HDAC3) serves as an "eraser" of Khib marks.
