Binds to the IL-1 type I receptor following IL-1 engagement, triggering intracellular signaling cascades leading to transcriptional up-regulation and mRNA stabilization. Interacts with MYD88. IL-1 stimulation leads to the formation of a signaling complex which dissociates from the IL-1 receptor following the binding of PELI1. Expressed in spleen, thymus, prostate, lung, liver, skeletal muscle, kidney, pancreas and peripheral blood leukocytes. Belongs to the protein kinase superfamily. TKL Ser/Thr protein kinase family. Pelle subfamily. Note: This description may include information from UniProtKB.
Protein type: Protein kinase, TKL; Protein kinase, Ser/Thr (non-receptor); Kinase, protein; TKL group; IRAK family
SS: The number of records in which this modification site was determined using site-specific methods. SS methods include amino acid sequencing, site-directed mutagenesis, modification site-specific antibodies, specific MS strategies, etc.
