PASK Protein, Human (Sf9, GST)

PASK is an important serine/threonine protein kinase that complexly regulates energy homeostasis and protein translation. It phosphorylates key targets (EEF1A1, GYS1, PDX1, RPS6) in response to changing environmental conditions (e.g., oxygen levels and nutritional status). PASK Protein, Human (Sf9, GST) is the recombinant human-derived PASK protein, expressed by Sf9 insect cells , with N-GST labeled tag. The total length of PASK Protein, Human (Sf9, GST) is 375 a.a., .

PASK, a serine/threonine-protein kinase, intricately contributes to energy homeostasis and protein translation. It exerts its regulatory influence by phosphorylating key targets, including EEF1A1, GYS1, PDX1, and RPS6. Notably, PASK appears to play a pivotal role in response to changing environmental conditions, such as alterations in oxygen levels, glucose availability, and nutritional status, rather than functioning under standard conditions. Acting as a sensor for energy homeostasis, PASK orchestrates glycogen synthase synthesis through the phosphorylation of GYS1, resulting in GYS1 inactivation. While its potential involvement in glucose-stimulated insulin production in the pancreas and the regulation of glucagon secretion by glucose in alpha cells awaits further substantiation, PASK is suggested to contribute to the modulation of protein translation. By phosphorylating EEF1A1, PASK enhances translation efficiency, implicating its role in finely tuning cellular responses to varying environmental cues. Additionally, PASK's potential engagement in respiratory regulation further underscores its multifaceted role in cellular homeostasis.
