The focus of my research group is to understand the molecular mechanisms that regulates signalling enzymes. We combine the information derived from biomolecular NMR spectroscopy, X-ray crystallography, and additional biophysical techniques, such as ITC, DSC, Biacore, and CD spectroscopy. Enzymes of key interests are ser/thr protein phosphatases (PP1, PP2B), tyr phosphatases and ser/thr kinases, especially MAP Kinases. Furthermore, my research group is pursuing an molecular understanding for the formation of bacterial biofilms.

Research Description

Signaling cascades direct information and, in turn, function from memory to muscle movement important at any stage of life. These cascades are mediated by a network of highly specific, tightly regulated series of protein:protein interactions, including those made by Serine/Threonine kinases and Serine/Threonine phosphatases. Our long-term goal is to achieve an in-depth understanding of this signaling network in the post synaptic density so we will be able to develop highly specific drugs for diseases such as Down's syndrome and mental retardation. Therefore we have started to investigate the role of the Serine/Threonine phosphatase Protein Phosphatase 1 (PP1) in neuronal signaling, as it is one of the most important protein phosphatases in the brain. Two of the major interaction partners of PP1 in neurons are the large, multi-domain scaffolding proteins Spinophilin and Neurabin. These proteins target PP1 to its cellular point of action, the post synaptic density of dendritic spines. This targeting of PP1 by Spinophilin and Neurabin is responsible for the PP1-mediated regulation of glutamatergic AMPA/NMDA channel activity. To understand the Spinophilin/PP1 and Neurabin/PP1 signaling networks in molecular detail, we will use NMR spectroscopy to elucidate the scaffolding properties of the Spinophilin and Neurabin protein interaction domains, both as isolated domains and in complex with their interaction peptides and binding proteins. Spinophilin and Neurabin also bind and organize actin. It has been shown that this organization is of key importance for dendritic synapses shape and therefore for early childhood learning, development, and memory. Therefore, these 3-dimensional structures, interaction maps, and biochemical studies will provide a detailed understanding of this specificity and will allow us to selectively modulate particular signaling cascades for medical benefit.

Teaching Experience

BI0019 S10: Proteins (Biology Foundations Courses)
Fall 2005; Fall 2006;

Freshmen Seminar Course: Students beginning in college-level biology are encouraged to choose a section of BI 19, courses that introduce biological sciences within the framework of particular topics. All BI 19 courses carry concentration credit in biology programs. In order to assure student/faculty interaction, these sections are limited in size. BI 19 courses are often suitable for students entering with AP biology credit. Some of these courses are designated as First Year Seminars.
Proteins are the expression of information in our genes. They help metabolize the food we eat, transport the air we breath, build our bodies, and color our eyes. To do so, they adopt a myriad of structural motifs. We examine the structural features of proteins and their functional consequences, as well as methods to experimentally determine or theoretically predict protein structure.
This course has been completely reorganized with a focus on modern techniques and approaches to protein structure analysis and a discussion of the structures of recently elucidated proteins and protein complexes, such as the ribosome.

BI0294 S1: Modern Topics in Structural Biology
Spring 2006;

An introduction into the modern approaches for structural biology; special focus was given to NMR spectroscopy methodology including recently introduced hardware, software and theoretical approaches. Examples for techniques were discussed using selected structures recently solved using NMR Spectroscopy. This was a completely new course at Brown University. The class was offered in a highly interactive arrangement including demonstrations at the NMR spectrometer.

This is focusing on protein expression and purification, synthetic biology, chemical biology, introduction into biophysical techniques and an in-depth introduction into structural biology. This medium class size allows for much discussion and even student presentations.
