STK33 (丝氨酸/苏氨酸激酶 33)

Serine/Threonine Kinase 33 (STK33) plays a pivotal role in cancer cell proliferation and metastasis by phosphorylating serine and threonine residues on proteins, thereby regulating crucial cellular processes such as signal transduction, DNA replication, cell differentiation, proliferation, apoptosis, and tumor development. STK33 is overexpressed in various cancers, including pancreatic, lung, and liver cancers, compared to non-cancerous tissues. Notably, STK33 activates the PI3K/Akt/mTOR signaling pathway in gastric cancer, promoting metastasis. Additionally, the STK33/ERK2 signaling pathway contributes to the tumorigenesis of colorectal cancer by phosphorylating ERK2, enhancing its activity and promoting cancer progression. STK33's involvement in cancer development underscores its importance in oncology research.^[1][2].
