Summaries for JAK1 Gene

Entrez Gene Summary for JAK1 Gene

  • 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 and interferon-gamma signal transduction. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Mar 2016]

GeneCards Summary for JAK1 Gene

JAK1 (Janus Kinase 1) is a Protein Coding gene. Diseases associated with JAK1 include Hepatitis C and Hepatitis. Among its related pathways are Interferon gamma signaling and RET signaling. GO annotations related to this gene include transferase activity, transferring phosphorus-containing groups and protein tyrosine kinase activity. An important paralog of this gene is TYK2.

UniProtKB/Swiss-Prot for JAK1 Gene

  • Tyrosine kinase of the non-receptor type, involved in the IFN-alpha/beta/gamma signal pathway (PubMed:7615558). Kinase partner for the interleukin (IL)-2 receptor (PubMed:11909529).
