RPS6KB1 phosphorylated on T252 is kinase-active. 2 / 2

"A critical step in S6 kinase 1 (S6K1) activation is Thr(229) phosphorylation in the activation loop by the phosphoinositide-dependent protein kinase (PDK1)."

"from full text - T229 is situated in the catalytic domain of p70S6K, and in addition to T389, its phosphorylation is necessary for full activation of the protein. Residues T421 and S424 are situated in the autoinhibitory/pseudosubstrate domain of the C-terminus, and phosphorylation of these residues is proposed to be one of the early steps of p70S6K activation (2)."
