Evolutionary dynamics of gene and isoform regulation in Mammalian tissues.
Most mammalian genes produce multiple distinct messenger RNAs through alternative splicing, but the extent of splicing conservation is not clear. To assess tissue-specific transcriptome variation across mammals, we sequenced complementary DNA from nine tissues from four mammals and one bird in biological triplicate, at unprecedented depth. We find that while tissue-specific gene expression prog...
متن کاملSelf-assembly pathway of nonsarcomeric myosin II.
Cells need to control the location and timing of actomyosin-dependent force generation, and appear to do so in the first instance by regulating myosin filament self-assembly (Yumura and Fukui, 1985). The mechanism of the self-assembly is little understood. In vitro it is a true self-assembly, which requires a short domain at the C terminus of the myosin molecule. The availability of this domain...
متن کاملThe regulation of myosin II in Dictyostelium.
Dictyostelium conventional myosin (myosin II) is an abundant protein that plays a role in various cellular processes such as cytokinesis, cell protrusion and development. This review will focus on the signal transduction pathways that regulate myosin II during cell movement. Myosin II appears to have two modes of action in Dictyostelium: local stabilization of the cytoskeleton by myosin filamen...
متن کاملCyclic AMP regulation of myosin isozymes in mammalian cardiac muscle
Hyperpermeable cells from rat heart contain a cAMP-dependent system that can increase the maximum Ca-activated force (contractility) of the contractile proteins. In two different conditions where the relative concentration of the myosin isozymes changes, i.e., hypothyroidism and aging, the size of the increase in contractility from activation of the cAMP-regulated system varies closely with the...
متن کاملA Role for Myosin II in Mammalian Mitochondrial Fission
Mitochondria are dynamic organelles, undergoing both fission and fusion regularly in interphase cells. Mitochondrial fission is thought to be part of a quality-control mechanism whereby damaged mitochondrial components are segregated from healthy components in an individual mitochondrion, followed by mitochondrial fission and degradation of the damaged daughter mitochondrion. Fission also plays...
