Major signaling cascades have been shown to play a role in the regulation of intracellular organelle transport . Aggregation and dispersion of pigment granules in melanophores are regulated by the second messenger cAMP through the protein kinase A (PKA) signaling pathway ; however, the exact mechanisms of this regulation are poorly understood. To study the(More)
Interphase microtubules are organized into a radial array with centrosome in the center. This organization is a subject of cellular regulation that can be driven by protein phosphorylation. Only few protein kinases that regulate microtubule array in interphase cells have been described. Ste20-like protein kinase LOSK (SLK) was identified as a microtubule(More)
We studied the distribution of mRNAs involved in dorsoventral differentiation of Xenopus laevis embryos (Xbra, chordin, Xnot, Xvent1, Xvent2, and Xwnt11) among polyribosomes (the translated form of mRNA) and informosomes (the nontranslated form of mRNA). It was shown using molecular hybridization that all of the studied templates are in the informosomes(More)
