Supplementary information

SIK3 also known as salt-inducible kinase 3 is a serine/threonine-protein kinase with a molecular mass of approximately 140 kDa. This protein is expressed in many tissues including liver muscle and pancreas. Mechanically SIK3 phosphorylates key substrates involved in the regulation of various cellular functions enhancing or inhibiting their activity. Its action often involves regulating metabolism cytokine signaling and cellular growth processes.
Biological function summary

SIK3 participates in the regulation of glucose metabolism and energy homeostasis. It acts as part of larger complexes that control transcription factors and enzymes related to metabolic processes. These complexes help respond to cellular signals and external stress adjusting cellular functions to maintain balance. It influences the activity of enzymes and transcriptional regulators involved in lipid and carbohydrate metabolism playing a role in energy balance maintenance.

Pathways

SIK3 influences gluconeogenesis and insulin signaling pathways. It is closely connected with proteins such as AMPK (AMP-activated protein kinase) regulating energy sensor mechanisms and metabolic stress responses. These pathways are critical in controlling glucose production and utilization which affect overall energy homeostasis in the body.

SIK3's dysfunction links to metabolic disorders like type 2 diabetes and obesity. Altered SIK3 activity affects insulin signaling which can contribute to impaired glucose regulation. It also connects to the protein LKB1 (liver kinase B1) in metabolic disease contexts as both play roles in regulating energy metabolism and maintaining glucose levels. Understanding SIK3's role provides insights for targeting metabolic diseases through therapeutic strategies.
