TYK2 - tyrosine kinase 2 Gene

Homo sapiens

Also known as JTK1; IMD35

Gene ID: 7297 | Gene type: protein coding

About TYK2

Cytogenetic location: 19p13.2 Genomic coordinates (GRCh38): 19:10,350,533-10,380,572 (from NCBI)

This gene has 35 transcripts (splice variants), 197 orthologues, 32 paralogues and is associated with 4 phenotypes. Ubiquitous expression in spleen (RPKM 21.6), bone marrow (RPKM 20.9) and 25 other tissues.

Summary

This gene encodes a member of the tyrosine kinase and, more specifically, the Janus kinases (JAKs) protein families. This protein associates with the cytoplasmic domain of type I and type II cytokine receptors and promulgate cytokine signals by phosphorylating receptor subunits. It is also a component of both the type I and type III interferon signaling pathways. As such, it may play a role in anti-viral immunity. A mutation in this gene has been associated with Immunodeficiency 35. [provided by RefSeq, Sep 2020]
