Regulation of mRNA translation, the process by which ribosomes decode mRNAs into polypeptides, is used to tune cellular protein levels. Currently, methods for observing the complete process of translation from single mRNAs in vivo are unavailable. Here, we report the long-term (>1 hr) imaging of single mRNAs undergoing hundreds of rounds of translation in(More)
Myosin phosphorylation plays an important part in excitation--contraction coupling in smooth muscle. Phosphorylation by a Ca2+, calmodulin-dependent kinase stimulates the actin-activated Mg2+-ATPase activity of smooth muscle myosin, suggesting that myosin phosphorylation regulates smooth muscle contraction. This hypothesis is supported by evidence that(More)
