Why is myelin important in the nervous system? A. It allows signals to travel faster along axons because depolarization occurs only at myelinated locations. B. It allows signals to travel faster along axons because depolarization occurs only at nonmyelinated locations. C. It bundles the dendrites of adjacent neurons together. D. It increases capacitance across the cell membrane, which helps electrical signals to leave the axons. E. It traps neurotransmitters, increasing their concentratio...

A second group, the neuronal clFps, are related more in terms of intron/exon structure than primary se- quence. This group contains the rather divergent clF proteins NF1, NFm, NFh, 0t-internexin and nestin. It appears that these proteins can all co-polymerize with vimentin and, from the point of view of IF network formation, may be viewed as partners of vimentin. There is, however, a clear-cut distinction between the [-352 amino acid central s-helical domain Nuclear lamins -I N...

At this point, I would like briefly to draw attention to an intriguing and rather heterodox proposal, made by Lai et al. [61"]. Vimentin is a major cellular phosphoprotein and its level of phosphorylation changes during the cell cycle. Aside from a likely role in the disruption of vimentin filaments in the region of the contractile ring during cytokinesis (see [62,63]), the physiological significance ofvimentin phosphorylation remains unclear. On the basis of a study of four diffe...
