LabRoots Hosts Cell Signaling Technology Webinar that Illuminates BioPlex Protein Interaction Network

The Webinar will discuss how affinity purifications can be performed at scale, the associated caveats, and how an interaction network can be used to predict a protein’s cellular properties, March 24, 2016

Steven Gygi, PhD - Professor in the Department of Cell Biology, Harvard Medical School

Thousands of protein-protein interactions combine to create a powerful network. The structure of this network drives cellular function and its organization underpins all biological inquiry. Scientists using high-throughput affinity-purification mass spectrometry have identified interacting partners for 2,594 human proteins in HEK293T cells. Consequently, the network that emerges (BioPlex) consists of 23,744 interactions, 86% unknown, among 7,668 proteins.

BioPlex precisely depicts known complexes, achieving 80% to 100% coverage for most CORUM complexes. The network’s framework consists of four main features: |1| BioPlex subdivides into >300 communities, joining proteins with shared function. |2| Interactions predict 2,968 associations between co-occurring Pfam domains. |3| Characteristic features such as localization, biological process, and molecular function were determined for thousands of proteins - many uncharacterized. |4| BioPlex brings to light interactions of biological or clinical significance. The scientists examined interactions of wild-type and mutant VAPB variants implicated in familial Amyotrophic Lateral Sclerosis to demonstrate complementary studies inspired by BioPlex. The network offers a framework for hypothesis generation and refinement focused on protein function, mechanism, and activity.

Cell Signaling Technology is sponsoring a new, free educational webinar, “BioPlex: a protein interaction network created from thousands of protein immunopurifications,” which will discuss the ways in which affinity purifications can be performed at scale and the associated caveats, and how an interaction network can be used to predict a protein’s cellular properties. PACE Continuing Education Credits will be offered.

The speaker is Steven Gygi, PhD, professor in the Department of Cell Biology at Harvard Medical School. A leading technologist, Dr. Gygi uses mass spectrometry to answer fundamental questions in normal and abnormal biology. He specializes in instrumentation advances for global cellular protein measurements. Dr. Gygi received his PhD from the University of Utah in the area of pharmacology and toxicology, and performed a postdoctoral fellowship with Ruedi Aebersold at the University of Washington. He joined the faculty at Harvard Medical School in 2000.

The complementary webinar, hosted by LabRoots, will be presented on March 24, 2016, at 10 am Pacific Time/1 pm Eastern Time.
