PF18377FERM F2 acyl-CoA binding protein-like domain (FERM_F2)FERM F2 acyl-CoA binding protein-like domainThis is an F2 lobe domain consisting of an acyl-CoA binding protein fold found in FERM region of Jak-family tyrosine kinases [1]. Multidomain JAK molecules interact with receptors through their FERM and SH2-like domains, triggering a series of phosph ...This is an F2 lobe domain consisting of an acyl-CoA binding protein fold found in FERM region of Jak-family tyrosine kinases [1]. 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].

PF21990SH2 domain (SH2_1)SH2 domainThe SH2 domain is a protein module that folds to form a pocket into which a phosphorylated tyrosine residue fits. SH2 domains discriminate their targets by making important contacts with residues from position +1 up to +4 in the ligand peptide. SH2 d ...The SH2 domain is a protein module that folds to form a pocket into which a phosphorylated tyrosine residue fits. 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.

PF17887Jak1 pleckstrin homology-like domain (Jak1_Phl)Jak1 pleckstrin homology-like domainThis entry is for the pleckstrin homology-like (PHL) subdomain found in Jak1 proteins. JAK1 is a member of the Janus kinase (JAK) family of non-receptor tyrosine kinases that are activated in response to cytokines and interferons.

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].
