General annotation (Comments)

Function

Receptor for IL1A, IL1B and IL1RN. After binding to interleukin-1 associates with the corecptor IL1RAP to form the high affinity interleukin-1 receptor complex which mediates interleukin-1-dependent activation of NF-kappa-B, MAPK and other pathways. Signaling involves the recruitment of adapter molecules such as TOLLIP, MYD88, and IRAK1 or IRAK2 via the respective TIR domains of the receptor/coreceptor subunits. Binds ligands with comparable affinity and binding of antagonist IL1RN prevents association with IL1RAP to form a signaling complex By similarity.

Subunit structure

The interleukin-1 receptor complex is a heterodimer of IL1R1 and IL1RAP. Interacts with PIK3R1 By similarity.

Subcellular location

Membrane; Single-pass type I membrane protein. Cell membrane Probable. Secreted By similarity.

Post-translational modification

A soluble form (sIL1R1) is probably produced by proteolytic cleavage at the cell surface (shedding) By similarity.

Rapidely phosphorylated on Tyr-499 in response to IL-1, which creates a SH2 binding site for the PI 3-kinase regulatory subunit PIK3R1 By similarity.

Sequence similarities

Belongs to the interleukin-1 receptor family.

Contains 3 Ig-like C2-type (immunoglobulin-like) domains.

Contains 1 TIR domain.

Sequence caution

The sequence AAA16196.1 differs from that shown. Reason: Erroneous initiation.
