This supplementary information is collated from multiple sources and compiled automatically.

Styk1 also known as Serine/threonine/tyrosine kinase 1 or NOK functions as a receptor protein kinase with a mass of approximately 100 kDa. This protein belongs to the receptor tyrosine kinase (RTK) family which is important in signaling pathways. Styk1 is expressed in various tissues with higher levels noted in testis and prostate tissues but it is also found in the brain and liver. Its structure contains both serine/threonine and tyrosine kinase activity contributing to its diverse role in cellular signaling.

Biological function summary

Styk1/NOK influences cell proliferation survival and differentiation. This kinase localizes at the plasma membrane where it participates in transmembrane signaling. It does not form classic receptor-ligand complexes but still greatly affects cellular responses by phosphorylating target proteins. Importantly through its enzymatic action Styk1 influences pathways that affect cell cycle regulation implying a role in cellular growth and maintenance.

Pathways

The kinase activity of Styk1/NOK impacts the PI3K/AKT signaling pathway an important regulator of metabolism and survival signals. This pathway involves interactions with proteins such as AKT1 and mTOR which are essential for mediating cellular responses to growth signals. Styk1/NOK also influences the MAPK signaling pathway again affecting a network of proteins important for controlling cell growth and survival.

Researchers link Styk1/NOK to cancer progression particularly in lung and prostate cancer. Elevated Styk1 levels associate with increased tumor growth and aggressiveness. This connection involves proteins like EGFR and MET which are well known to be associated with oncogenic processes. Understanding the role of Styk1/NOK in such diseases can provide insights into potential therapeutic targets and treatment strategies.
