Description

General description

Janus kinase 1 (JAK1) is encoded by the gene mapped to human chromosome 1p31.3. The encoded protein is one of the four members of the mammalian JAK families. Members of JAK family contain an N-terminal FERM (four.1, ezrin, radixin, moesin) domain, through which they interact with cytokine receptors. The N-terminal end also contains an SH2-like domain. In addition, it also contains a kinase domain and a pseudo-kinase domain, which is catalytically inactive. JAK1 is ubiquitously expressed. When expressed without their receptors, JAKs reside in the cytosol. However, under normal cell conditions, they localize to plasma membrane and endosomes.

Immunogen

Peptide sequence around phosphorylation site of tyrosine 1022 (K-E-Y(p)-Y-T), according to the protein JAK1.

Application

Anti-phospho-JAK1 (pTyr1022) antibody produced in rabbit has been used in Western blot analysis.

Biochem/physiol Actions

Janus kinases (JAKs) are activated when cytokines bind with their receptors, upon which they phosphorylate the receptors and produce docking sites for signaling molecules. One of the main signaling molecules includes signal transducer and activator of transcription (Stat) family. JAK1 is needed by multiple cytokines, including the family using the shared receptor subunit called common γ chain (γc), such as interleukin (IL)-2, IL-4, IL-7, IL-9, IL-15 and IL-21. JAK1 KO (knockout) mice have early postnatal lethal or perinatal lethal phenotype due to neurological defects. In vitro studies show that JAK1S703I mutation functions as an activator of JAK-STAT pathways even in the absence of cytokines, and drives cellular proliferation. JAK1S703I mutant patient-derived xenograft (PDX) HCC (hepatocellular carcinoma) cells also show sensitivity to JAK1/2 inhibitor, ruxolitinib.
