CATEGORY

SUBCELLULAR LOCALIZATION	intracellular
	intracellular,cytoplasm,cytosolic

basic FUNCTION	acting as a serine/threonine kinase involved in the IL1 pathway, partially involved in IL1-induced upregulation of the transcription factor NF-kappa B
	playing an essential role in the activation of NFKB and JNK in response to IL18
	its activation is a key event in the transmission of signals from Toll-like receptors (TLRs)
	initiate a cascade of signaling events eventually leading to induction of inflammatory target gene expression
	serine/threonine protein kinase involved in the signaling cascade of the Toll/IL-1 receptor (TIR) family
	being an essential regulator for lipopolysaccharide-induced interleukin-10 gene expression
	pivotal regulator of the NFKB pathway
	having a kinase activity redundant with that of IRAK4
	MYD88 and the associated kinases IRAK1 and IRAK4 are essential for activated B-cell-like (ABC) subtype of diffuse large B-cell lymphoma (DLBCL) survival
	MYD88 and IRAK1 are required to maintain the viability of ABC DLBCL cells

CELLULAR PROCESS

PHYSIOLOGICAL PROCESS

immunity/defense

PATHWAY

metabolism

signaling

signal transduction

bacterial LPS proapoptotic complex pathways diverging downstream IRAK1 towards to NF-kappa BL activation or apoptosis

a component	forming a complex with IL1R1 after induction by IL1 through its association with IL1RAP
	subsequently interacting with TRAF6 required for IL-1 mediated NFKB activation (see symbols)

INTERACTION

DNA

RNA

small molecule	cofactor, nucleotide,
	Mg2+
	ATP

protein	MYD88, TRAF6, IKK complex (to mediating IL1 beta signal transduction)
	binding to the IL-1 type I receptor following IL-1 engagement
	activating PELI1, PELI2, PELI3
	TIRAP is a substrate for IRAK1 and IRAK4 and is likely an important control mechanism in TLR2 and TLR4 signal transduction
	IRAK1 catalytic activity is not triggered by a covalent modification but by an allosteric mechanism induced by its interaction with IRAK4
