JAKs, STATs and signal transduction in response to the interferons and other cytokines

Abstract excerpt

The isolation and complementation of mutant human cell lines has established an essential role for the JAK (Janus kinase) family of protein tyrosine kinases and STAT (signal transduction and transcription) factors in the Interferon response pathways. Activation of STATs by JAKs occurs in receptor complexes at the cell membrane. Activated STATs form homo- or heterodimers and, with or without additional factors,...
