[Term] id: PR:000000568 name: ribosomal protein S6 kinase beta-1 isoform 2 phosphorylated 1 def: "A ribosomal protein S6 kinase beta-1 isoform 2 phosphorylated form in which the phosphorylation occurs within the AGC-kinase C-terminal domain. These sites serve as phosphorylation-regulated switches to control both intra- and inter-molecular interactions. Without these priming phosphorylations, the kinases are catalytically inactive."
