DESCRIPTION

Also known as INAR1_HUMAN, IFNAR1, IFNAR. Component of the receptor for type I interferons, including interferons alpha, IFNB1 and IFNW1 (PubMed:2153461, PubMed:7665574, PubMed:10049744, PubMed:14532120, PubMed:15337770, PubMed:21854986). Functions in general as heterodimer with IFNAR2 (PubMed:7665574, PubMed:10049744, PubMed:21854986). Type I interferon binding activates the JAK-STAT signaling cascade, and triggers tyrosine phosphorylation of a number of proteins including JAKs, TYK2, STAT proteins and the IFNR alpha- and beta-subunits themselves (PubMed:7665574, PubMed:21854986, PubMed:32972995). Can form an active IFNB1 receptor by itself and activate a signaling cascade that does not involve activation of the JAK-STAT pathway (By similarity). Heterodimer with IFNAR2 (PubMed:7665574, PubMed:10049744, PubMed:21854986). Interacts with STAT1 and STAT2; the interaction requires its phosphorylation at Tyr-466 (PubMed:9121453). Interacts with TYK2 (PubMed:7526154, PubMed:15337770, PubMed:24704786). Interacts (serine-phosphorylated form) with FBXW11, the substrate recognition component of a SCF (SKP1-CUL1-F-box protein) E3 ubiquitin-protein ligase complex (PubMed:14532120, PubMed:15337770, PubMed:18056411). Interacts with SHMT2; this promotes interaction with ABRAXAS2 and the BRISC complex (PubMed:24075985). Interacts with TRIM10; this interaction prevents association between IFNAR1 and TYK2 (PubMed:33811647).
