interpersonal function of language in subtitling
translation as a comunicative process is always said to be associated with various aspects of meaning loss or gain. subtitling as a mode of translating, due to special discoursal and textual conditions imposed upon it, is believed to be an obvious case of this loss or gain. presenting the spoken sound track of a film in writing and synchronizing the perception of this text by the viewers with...
15 صفحه اولRegulation of microtubule-based transport by MAP4
Microtubule (MT)-based transport of organelles driven by the opposing MT motors kinesins and dynein is tightly regulated in cells, but the underlying molecular mechanisms remain largely unknown. Here we tested the regulation of MT transport by the ubiquitous protein MAP4 using Xenopus melanophores as an experimental system. In these cells, pigment granules (melanosomes) move along MTs to the ce...
متن کاملPhosphorylation of MAP4 affects microtubule properties and cell cycle progression.
In human cells, MAP4, a microtubule-associated protein ubiquitously expressed in proliferating cells, has been shown to undergo in vivo phosphorylation. Two phosphorylation sites, serines 696 and 787, lie within the proline-rich region of its microtubule-binding domain. To test the hypothesis that phosphorylation at these sites influences microtubule properties or cell cycle progression, we pre...
متن کاملOverexpression of MAP4 inhibits organelle motility and trafficking in vivo.
We previously prepared cell lines that inducibly overexpress MAP4, a microtubule (MT)-associated protein widely expressed in non-neuronal cells. Overexpression of either the full-length MAP4 molecule or its MT-binding domain, MTB, stabilized MTs and retarded cell growth, suggesting that overexpressed MAP4 impacts on MT-dependent functions in vivo. To test this hypothesis, we examined MT-based v...
متن کاملRegulation of CFTR expression and function by NOS isoforms
Background The cystic fibrosis transmembrane conductance regulator (CFTR) is the gene of interest in the eponymous disease, cystic fibrosis (CF). CFTR is expressed in epithelial cells and functions as a chloride channel. Several hundred mutations are known to occur in CF patients, but the most prevalent mutation is the deletion of phenylalanine at position 508 (ΔF508). Although the mutated prot...
