OverviewAI-generated summary
Irina D. Pokrovskaya's research focuses on the molecular mechanisms underlying cellular transport and organelle function, with a particular emphasis on the Golgi apparatus and platelet biology. Her work investigates the role of protein complexes, such as the Conserved Oligomeric Golgi (COG) complex and SNARE proteins, in vesicular transport and protein processing, including glycosylation.
Her recent publications have explored the impact of COG complex inactivation on Golgi dynamics and intra-Golgi recycling. Pokrovskaya has also studied the function of serglycin, a luminal proteoglycan, in platelet alpha-granule packaging and release, and examined the structure of venous puncture wound hemostasis. Furthermore, her research has extended to the application of deep learning and 3D ultrastructural analysis for quantitative assessment of platelet and organelle packing in COVID-19 patients, as well as the essential role of the COG complex in *Toxoplasma gondii*.
Pokrovskaya is a highly cited researcher with an h-index of 27 and over 2,000 citations. She has a significant publication record and collaborates extensively with researchers at the University of Arkansas for Medical Sciences, including Brian Storrie, Vladimir Lupashin, Kelly K. Ball, and Sung W. Rhee.
