Multidomain JAK molecules interact with receptors through their FERM and SH2-like domains, triggering a series of phosphorylation events, resulting in the activation of their kinase domains [2]. Overall, the FERM region maintains the typical three-lobed architecture, with an F1 lobe consisting of a ubiquitin-like fold, an F2 lobe consisting of an acyl-CoA binding protein fold, and an F3 lobe consisting of a pleckstrin-homology (PH) fold. JAK1 FERM-F2 domain has been shown to act as the interaction site for the IFNLR1 box1 motif (PxxLxF) of class II cytokine receptors which is essential for kinase activation [3].

SH2 domains discriminate their targets by making important contacts with residues from position +1 up to +4 in the ligand peptide. SH2 domain comprises two alpha-helices packed against each side of a central beta-sheet.

JAK1 is a member of the Janus kinase (JAK) family of non-receptor tyrosine kinases that are activated in response to cytokines and interferons. PHL (residues 283-419) together with the N-terminal ubiquitin-like subdomain (residues 36-111) and an acyl-coenzyme A binding protein-like subdomain (residues 148-282), associate into a canonical tri-lobed FERM domain [1].

Protein kinases catalyse the transfer of the gamma phosphate from nucleotide triphosphates (often ATP) to one or more amino acid residues in a protein substrate side chain, resulting in a conformational change affecting protein function. Phosphoprotein phosphatases catalyse the reverse process. Protein kinases fall into three broad classes, characterised with respect to substrate specificity [1]; Serine/threonine-protein kinases, tyrosine-protein kinases, and dual specificity protein kinases (e.g. MEK - phosphorylates both Thr and Tyr on target proteins). This entry represents the catalytic domain found in a number of serine/threonine- and tyrosine-protein kinases. It does not include the catalytic domain of dual specificity kinases.
