Ezrin activation by LOK phosphorylation involves a PIP2-dependent wedge mechanism.

eLife | Apr 21, 2017

How cells specify morphologically distinct plasma membrane domains is poorly understood. Prior work has shown that restriction of microvilli to the apical aspect of epithelial cells requires the localized activation of the membrane-F-actin linking protein ezrin. Using an in vitro system, we now define a multi-step process whereby the kinase LOK specifically phosphorylates ezrin to activate it. Binding of PIP2 to ezrin induces a conformational change permitting the insertion of the LOK C-terminal domain to wedge apart the membrane and F-actin-binding domains of ezrin. The N-terminal LOK kinase domain can then access a site 40 residues distal from the consensus sequence that collectively direct phosphorylation of the appropriate threonine residue. We suggest that this elaborate mechanism ensures that ezrin is only phosphorylated at the plasma membrane, and with high specificity by the apically localized kinase LOK.

Odyssey CLx

A data analysis software developed to simplify and record data from fluorescent related assays such as Western Blots, EMSAs, and Western Assays. This software will consolidate all of the resulting data into one easy-to-track image, and thus removes the need for multiple exposures, as well as standardizing the resulting fluorescent bands without image saturation, blowout, or removed sensitivity. Odyssey CLx is capable of scanning multiple mini-blots, microplates, or slides at the same time.

ATCC

Global nonprofit biological resource center (BRC) and research organization that provides biological products, technical services and educational programs to private industry, government and academic organizations. Its mission is to acquire, authenticate, preserve, develop and distribute biological materials, information, technology, intellectual property and standards for the advancement and application of scientific knowledge. The primary purpose of ATCC is to use its resources and experience as a BRC to become the world leader in standard biological reference materials management, intellectual property resource management and translational research as applied to biomaterial development, standardization and certification. ATCC characterizes cell lines, bacteria, viruses, fungi and protozoa, as well as develops and evaluates assays and techniques for validating research resources and preserving and distributing biological materials to the public and private sector research communities.

Addgene

A non-profit plasmid repository dedicated to helping scientists around the world share high-quality plasmids. Addgene’s mission is to accelerate research and discovery by improving access to useful research materials and information. We facilitate the sharing of high-quality scientific materials, research reproducibility, and open science by archiving and distributing DNA-based research reagents and associated data to scientists worldwide. Our repository contains over 65,000 plasmids, including special collections on CRISPR, fluorescent proteins, and ready-to-use viral preparations. There is no cost for scientists to deposit plasmids, which saves time and money associated with shipping plasmids themselves. All plasmids are fully sequenced for validation and sequencing data is openly available. We handle the appropriate Material Transfer Agreements (MTA) with institutions, facilitating open exchange and offering intellectual property and liability protection for depositing scientists. Furthermore, we curate free educational resources for the scientific community including a blog, eBooks, video protocols, and detailed molecular biology resources.
