Janus kinase (JAK) is a family of intracellular non-receptor tyrosine kinases, ranging from 120-140 kDa in size, that transduce cytokine-mediated signals via the JAK-STAT pathway. Initially discovered in a PCR-based screen of kinases and named ironically as "just another kinase" 1 & 2 (since they were two of a large number of new kinases discovered in the screen) JAK1 and JAK2 were ultimately published as Janus kinase 1 and Janus kinase 2. The name is taken from Janus, the Thessalian gatekeeper of heaven worshipped by the Romans; he is described as having two faces while the JAKs possess two near-identical phosphate-transferring domains. One domain exhibits the kinase activity while the other stabilises the JAK's conformational structure enabling it express that activity.
