Gloria Brar

Gloria Brar is a Professor of Cell Biology at the University of California, Berkeley, affiliated with the Department of Molecular and Cell Biology. Her research focuses on unraveling the molecular circuitry underlying meiotic differentiation, particularly the regulation of gene expression through integrated transcriptional, translational, and proteomic mechanisms. Her lab employs ribosome profiling and proteomic analyses to study how unconventional regulatory strategies govern protein synthesis, degradation, and cellular rejuvenation during gametogenesis.

Key research areas include: 1) mechanisms of translational control via uORFs and LUTI isoforms, 2) protein degradation dynamics during meiosis, and 3) stress pathways' roles in cellular rejuvenation. Her work has revealed non-canonical protein synthesis events such as short ORF-encoded peptides and alternative translation initiation sites. Collaborations with the Ünal lab explore how meiotic programs reset cellular aging markers.

Recent studies highlight the prevalence of protein isoforms generated via non-AUG start codons and their functional implications. The lab also investigates ribosome composition's impact on gene expression signatures during meiosis. Her findings challenge traditional models of gene regulation, emphasizing context-dependent mechanisms.

Publications span high-impact journals like Cell, Science, and Molecular Cell, with a focus on translating systems-level data into mechanistic insights. The Brar Lab actively explores applications to aging research and cellular quality control, leveraging budding yeast as a model system for conserved processes.
