Target Information
RPS6KA5 (MSK1) is a serine/threonine protein kinase essential for regulating various cellular processes. It mediates mitogen- or stress-induced phosphorylation of transcription factors such as CREB1 and ATF1, and regulates RELA, STAT3, and ETV1/ER81, contributing to gene activation via histone phosphorylation.
MSK1 plays a key role in inflammatory gene regulation and RELA transcriptional control in response to TNF and glucocorticoids. It associates with the glucocorticoid receptor NR3C1 to repress inflammatory gene expression. In skeletal myoblasts, it phosphorylates RELA at Ser-276 during oxidative stress, and in erythropoietin-stimulated cells, it is required for STAT3 Ser-727 phosphorylation and transcriptional regulation.
