Mirzaei Lab Logo

Welcome to the Mirzaei lab, of the Department of Biochemistry at UT Southwestern Medical Center in Dallas, Texas. The lab is headed by Hamid Mirzaei Ph.D. who is also the director of the UTSW Proteomics Core.

Research in the lab is centered around the development of quantitative targeted mass-spectrometry techniques in order to study differential gene and PTM regulations in cancer cells. See below for an overview, or take a look at the research page for more details.

Introduction

Selected Reaction Monitoring (SRM) is an emerging proteomics technology with the power to transform proteomics into an effective data acquisition platform with all the requirements posed by the systems biology roadmap. Recognizing its potential, in the past few years we have been focusing on the development and application of SRM mass spectrometry. Building upon this knowledge, my lab's research program will be focused on the development of analytical technologies that would alleviate limitations currently hindering proteomics from becoming an accurate high throughput data acquisition technology. In this effort we are focused on developing enhanced high resolution, high capacity separation and detection platform based on emerging SRM mass spectrometry for improved protein detection and quantification. My lab is also focused on developing new bioinformatics tools for processing the data generated by these advanced mass spectrometry methods. In the biological front we are focused on developing SRM assays to study transcription regulation and protein ubiquitination. In this effort a portion of my lab's research program is dedicated to the development of new enrichment techniques for class-specific and post-translationally modified proteins, a step essential for successful analyses of low abundance proteins.

My lab's research program encompasses innovation of protein enrichment methods, advances in SRM mass spectrometry techniques, and development of problem-specific computational tools for data processing. This program will serve as a solid foundation for large-scale integrative experiments that will provide the accurate and comprehensive data needed to gain insight into the complex cellular regulatory mechanisms.

Congratulations to Haoxin Li, who has been accepted to the Chemical Biology graduate program at Harvard University. Haoxin is a student from Wuhan University, China. He has spent the last six months at UTSW, working on research projects in the Mirzaei Lab. We wish Haoxin all the best for the future!


2/22/13 - Publication: Systematic measurement of transcription factor-DNA interactions by targeted mass spectrometry identifies candidate gene regulatory proteins.

Our latest publication in PNAS, which will be highlighted in an upcoming issue of Nature Chemical Biology uses SRM-based targeted proteomics to identify candidate gene regulatory proteins. A broad SRM study of 464 proteins with known or suspected roles in gene regulation in S. cerevisiae identified 15 regulators that interact with the FLO11 promoter. We demonstrate that Mot3 and Azf1 are required for FLO11 expression. See the paper at the link below:
