Plant growth is regulated by a multiplicity of factors, many of which are transduced via hormone signaling. However, how these hormone signals converge to affect growth is not entirely clear (reviewed in Depuydt and Hardtke, 2011). New work from Ikeda et al. (2012) and Bai et al. (2012) demonstrates that the cell elongation component of growth is regulated by a mechanism involving groups of thr...

altered glycosylation of proteins in cancer cells is one of the main processes responsible for anaplasia, invasion and metastatic potential of neoplastic cells. lectins are nonimmunogenetic compounds which specifically detect certain terminal sugars of glycoconjugates. the aim of the present study was to identify the n-acetylgalactosamine (galnac) containing glycoconjugates in cancer cells in a...

In this study, we introduce the natural mate and conjugate of a Frenet curve in three dimensional Lie group $ \mathbb{G} with bi-invariant metric. Also, give some relationships between its or $. Especially, obtain results for when is general helix, slant spherical curve, rectifying Salkowski (constant curvature non-constant torsion), anti-Salkowski (non-constant constant Bertrand curve. Finally...

Hsp90 is a ubiquitous, well-conserved molecular chaperone involved in the folding and stabilization of diverse proteins. Beyond its capacity for general protein folding, Hsp90 influences a wide array of cellular signaling pathways that underlie key biological and disease processes. It has been proposed that Hsp90 functions as a molecular clamp, dimerizing through its carboxy-terminal domain and...

Polymers, including biomolecules such as proteins, have two particularly important types of single-molecule transitions: a helix-coil transition, driven by interactions that are local in the chain, and a collapse transition, driven by nonlocal interactions. A long-standing challenge of polymer statistical mechanics has been to deal with both types of transition in a single theoretical framework...

The mechanism of chain selection and trimerization of fibril-associated collagens with interrupted triple helices (FACITs) differs from that of fibrillar collagens that have special C-propeptides. We recently showed that the second carboxyl-terminal non-collagenous domain (NC2) of homotrimeric collagen XIX forms a stable trimer and substantially stabilizes a collagen triple helix attached to ei...
