GRP75 is a multipotent chaperone regulating cellular processes ranging from stress response to neurodegeneration. As the only ATPase component of the pre-protein mitochondrial import machinery, GRP75 plays a key role in multiple basic mitochondrial processes, including mitochondrial protein import, ...

Effect of GRP75 deficiency on gene expression in DN3 thymocytes
Effect of GRP75 deficiency on gene expression in different subsets of CD8+ T cells
The development and functional maintenance of CD8+ T cells are metabolically regulated processes in which mitochondria serve as the central hub. Here, we identify glucose-regulated protein 75 (GRP75) as a critical mitochondrial regulator controlling these processes. Using T cell-specific Hspa9 (enco...

Mitochondria and endoplasmic reticulum contacts (MERCs) regulate multiple cellular processes including cell survival and differentiation. Based on the observations that MERCs were specifically enriched in the CD4-CD8- double negative (DN) stage, we studied their role in early thymocyte development. ...

This study investigates the role of GRP75 (Hspa9)-mediated mitochondria-associated membranes (MAMs) in SARS-CoV-2 nucleocapsid (N) protein-induced acute lung injury. Using single-cell RNA sequencing of lung macrophages from control and GRP75 knockdown mice, we demonstrate that N protein promotes GRP...
