JAK1 - Janus kinase 1 Gene
Also Known as JTK3; AIIDE; JAK1A; JAK1B
Species: Homo sapiens
About JAK1
This gene has 31 transcripts (splice variants), 238 orthologues, 32 paralogues and is associated with 113 phenotypes. Ubiquitous expression in lymph node (RPKM 51.3), fat (RPKM 49.8) and 25 other tissues.
Summary
This gene encodes a membrane protein that is a member of a class of protein-tyrosine kinases (PTK) characterized by the presence of a second phosphotransferase-related domain immediately N-terminal to the PTK domain. The encoded kinase phosphorylates STAT proteins (signal transducers and activators of transcription) and plays a key role in interferon-alpha/beta, interferon-gamma, and cytokine signal transduction. This gene plays a crucial role in effecting the expression of genes that mediate inflammation, epithelial remodeling, and metastatic Cancer progression. This gene is a key component of the interleukin-6 (IL-6)/JAK1/STAT3 immune and inflammation response and is a therapeutic target for alleviating cytokine storms. The kinase activity of this gene is directly inhibited by the suppressor of cytokine signalling 1 (SOCS1) protein. Alternative splicing results in multiple transcript variants.
