MSH: A Janus kinase subtype that is predominantly expressed in hematopoietic cell. It is involved in signaling from a broad variety of CYTOKINE RECEPTORS including ones that utilize the INTERLEUKIN RECEPTOR COMMON GAMMA SUBUNIT.,NCI: This protein is a member of janus family. JAK3 functions in signal transduction and interacts with members of the STAT (signal transduction and activators of transcription) family. JAK3 is predominantly expressed in immune cells and transduces a signal in response to its activation via tyrosine phosphorylation by interleukin receptors. Mutations that abrogate janus kinase 3 function cause an autosomal SCID (severe combined immunodeficiency disease). (from LocusLink)
