Protein Information (annotations from UniProt)

Database IDHIV0014033
UniProt IDP14778
Primary gene name(s)IL1R1
Synonym gene name(s)IL1R, IL1RA, IL1RT1
Protein nameInterleukin-1 receptor type 1
Protein functionReceptor for IL1A, IL1B and IL1RN. After binding to interleukin-1 associates with the coreceptor 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. {ECO:0000269|PubMed:10671496}.
