Water homeostasis is crucial to the growth and survival of plants. Plasma membrane intrinsic proteins (PIPs) have been shown to be primary channels mediating water uptake in plant cells. We characterized a novel PIP2 gene, HvPIP2;8 in barley (Hordeum vulgare). HvPIP2;8 shared 72-76% identity with other HvPIP2s and 74% identity with rice OsPIP2;8. The gene was expressed in all organs including t...

Previous studies provided evidence for the alteration of brain cholesterol homeostasis in 129.Mecp2-null mice, an experimental model of Rett syndrome. The efficacy of statins in improving motor symptoms and prolonging survival of mutant mice suggested a potential role of statins in the therapy of Rett syndrome. In the present study, we show that Mecp2 deletion had no effect on brain and reduced...

Clathrin-mediated membrane trafficking is critical for multiple stages of plant growth and development. One key component of clathrin-mediated trafficking in animals is dynamin, a polymerizing GTPase that plays both regulatory and mechanical roles. Other eukaryotes use various dynamin-related proteins (DRP) in clathrin-mediated trafficking. Plants are unique in the apparent involvement of both ...

The silencing of actin capping protein ß2, Capzb2, by RNAi in developing cultured neurons results in short, dystrophic neurites reminiscent of cytoskeletal changes seen in diverse neurodegenerative diseases, including Alzheimer’s disease (AD) and Huntington’s disease (HD). Actin and tubulin are two major cytoskeletal proteins indispensable for normal neurite development and regenerative respons...

The properties of the microtubule network are regulated at various levels including tissue-dependent isotype switching, post-translational modification of αand β-tubulin, and by a variety of microtubuleassociated molecules (for reviews, see [1–3]). Microtubule nucleation is attributed to γ-tubulin, which is present in protein complexes at the centrosome and in the cytoplasm [4,5]. A screen for ...
