Welcome to the Mirzaei lab in the Department of Biochemistry at UT Southwestern Medical Center in Dallas, Texas. We develop and use state-of-the-art mass-spectrometry proteomics techniques to address important biological questions.
Research in the lab is centred around developing proteomics methods that can be applied to a wide range of important biological research. We have interests including: the in-depth study of protein ubiquitination; comprehensive identification of protein complexes; identification of drug and pathogen targets; development of methods and software to improve proteomics data analysis.

Our newest work, published in Mol. Cell. Proteomics is Confetti, a multi-enzyme map of the HeLa proteome. We used 48 single and combination digests to exhaustively analyze HeLa lysate using Orbitrap Elite and Q Exactive mass-spectrometry. We provide an online resource for researchers to identify the best digest to achieve coverage of a protein or region of sequence of interest. In addition, we demonstrated that alternative enzyme digest may give better sensitivity for some proteins in SRM experiment.
