Recruited STAT5 is phosphorylated

Locations in the PathwayBrowser

STAT5 alpha and beta are recruited to the receptor complex and phosphorylated. JAK3 is believed to be responsible for the tyrosine phosphorylation of STAT5 in response to IL-2; it is not clear whether JAK1 is also involved (Lin & Leonard, 2000). Tyr-694 of STAT5a and Tyr-699 of STAT5b are required for IL-2 induced STAT5 activation (Lin et al. 1996). STAT5a and STAT5b are also known to be serine phosphorylated in lymphocytes activated by IL-2 but the funtion of this is unclear (Xue et al. 2002).
