Bioinformatic comparison of human and higher plant phosphatomes

A journey through a plant cytoskeleton: Hot spots in signaling and functioning

This survey paper contains a brief analysis of publications included in the special issue of the scientific journal Cell Biology International titled "Plant Cytoskeleton Structure, Dynamics and Functions". The manuscripts in this special issue reflect some new aspects of plant cytoskeleton organization, signaling and functioning, and results from different Ukrainian research groups, and focuses on bringing together scientists working across different instrumental scales.

Protein phosphatases potentially associated with regulation of microtubules, their spatial structure reconstruction and analysis

According to the sequence and profile comparison with known catalytic domains, where identified protein phosphatases potentially involved in regulation of microtubule dynamics and structure from Arabidopsis thaliana, Nicotiana tabacum, Medicago sativa, Oryza sativa subsp. japonica, Zea mays, and Triticum aestivum. Selected proteins were related to classical non-receptor, serine/threonine-specific and dual protein phosphatases. By application of template structures of human protein phosphatases, it was performed homology modelling of the catalytic domains of 17 plant protein phosphatases. Based on the results of the structural alignment, molecular dynamics, and conservatism in positions of functionally importance, it was confirmed homology of selected plant proteins and known protein phosphatases regulating structure and dynamics of microtubules.
