Function
STAT proteins were originally described as latent cytoplasmic transcription factors that require phosphorylation for nuclear retention. The unphosphorylated STAT proteins shuttles between cytosol and the nucleus waiting for its activation signal. Once the activated transcription factors reaches the nucleus it binds to consensus DNA-recognition motif called gamma activated sites (GAS) in the promoter region of cytokine inducible genes and activates transcription of these genes.

“If the children and youth of a nation are afforded opportunity to develop their capacities to the fullest, if they are given the knowledge to understand the world and the wisdom to change it, then the prospects for the future are bright. In contrast, a society which neglects its children, however well it may function in other respects, risks eventual disorganization and demise.”
