Gene: JAK1 (Janus kinase 1) Homo sapiens
Symbol: JAK1
Name: Janus kinase 1
Description: 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]
Type: protein-coding
RefSeq Status: REVIEWED
