Janus kinase 2 (commonly called JAK2) is a non-receptor tyrosine kinase. It is a member of the Janus kinase family and has been implicated in signaling by members of the type II cytokine receptor family (e.g. interferon receptors) the GM-CSF receptor family (IL-3R IL-5R and GM-CSF-R) the gp130 receptor family (e.g. IL-6R) and the single chain receptors (e.g. Epo-R Tpo-R GH-R PRL-R).
