What is the Origin of JAK-STAT Pathway?

The pathway is named for its core components: the associated tyrosine kinases (JAKs) that phosphorylate the latent transcription factors (STATs) upon receptor binding. Understanding this mechanism illuminated how non-steroid hormones and immune mediators transmit signals across the cell membrane.

What is the Mechanism of JAK-STAT Pathway?

Upon ligand binding to a cell surface receptor, JAKs are activated and phosphorylate the receptor tails, creating docking sites for STAT proteins. Once phosphorylated by JAKs, STATs dimerize, translocate to the nucleus, and initiate the transcription of specific target genes, thereby controlling cellular proliferation, differentiation, and survival responses.

JAK-STAT Pathway

Meaning

Janus Kinase-Signal Transducer and Activator of Transcription is a fundamental intracellular signaling cascade primarily activated by cytokines and some growth factors, playing a key role in mediating cellular responses to external stimuli.
