[Term] id: PR:000021978 name: interleukin-1 receptor-associated kinase 1 isoform 1 phosphorylated 4 def: "An interleukin-1 receptor-associated kinase 1 isoform 1 phosphorylated form in which the phosphorylation occurs by interleukin-1 receptor-associated kinase 4 (IRAK-4) and extensively autophosphorylated in the Pro-, Ser-, and Thr-rich ProST region between the N-terminal death domain and kinase domain. Example: UniProtKB:P51617-1, Thr-209/Thr-387, MOD:00047|MOD:00046."
