NCIt definition : Tyrosine-protein kinase JAK2 (1132 aa, 131 kDa) is encoded by the human JAK2 gene.
This protein is involved in immunity, tyrosine phosphorylation and signal transduction.;
NCIt note : Janus kinases couple cytokine ligand binding to tyrosine phosphorylation of various
known signaling proteins and of a unique family of transcription factors termed the
signal transducers and activators of transcription, or STATs.;
