Function

Together with IFNAR2, forms the heterodimeric receptor for type I interferons (including interferons alpha, beta, epsilon, omega and kappa) (PubMed:10049744, PubMed:14532120, PubMed:15337770, PubMed:2153461, PubMed:21854986, PubMed:24075985, PubMed:31270247, PubMed:33252644, PubMed:35442418, PubMed:7813427). Type I interferon binding activates the JAK-STAT signaling cascade, resulting in transcriptional activation or repression of interferon-regulated genes that encode the effectors of the interferon response (PubMed:10049744, PubMed:21854986, PubMed:7665574). Mechanistically, type I interferon-binding brings the IFNAR1 and IFNAR2 subunits into close proximity with one another, driving their associated Janus kinases (JAKs) (TYK2 bound to IFNAR1 and JAK1 bound to IFNAR2) to cross-phosphorylate one another (PubMed:21854986, PubMed:32972995, PubMed:7665574, PubMed:7813427). The activated kinases phosphorylate specific tyrosine residues on the intracellular domains of IFNAR1 and IFNAR2, forming docking sites for the STAT transcription factors (PubMed:21854986, PubMed:32972995, PubMed:7526154, PubMed:7665574, PubMed:7813427). STAT proteins are then phosphorylated by the JAKs, promoting their translocation into the nucleus to regulate expression of interferon-regulated genes (PubMed:19561067, PubMed:21854986, PubMed:32972995, PubMed:7665574, PubMed:7813427, PubMed:9121453). Can also act independently of IFNAR2: form an active IFNB1 receptor by itself and activate a signaling cascade that does not involve activation of the JAK-STAT pathway (By similarity).

Activity summary

Interferon alpha/beta receptor 1 also known as IFNAR1 is an important component of the interferon receptor complex which includes the interferon beta receptor (IFNBR) and the broader class of interferon receptors. IFNAR1 is a transmembrane protein with a molecular mass of approximately 100 kDa. It shows expression in various tissues but predominantly in cells of the immune system. This expression pattern enables IFNAR1 to play a central role in mediating responses to interferon alpha and beta which are cytokines important in the immune response.

Biological function summary

IFNAR1 partners with interferon alpha receptor 2 (IFNAR2) to form a functional receptor complex. This complex binds interferons alpha and beta triggering signal transduction cascades vital for antiviral defense. Through this interaction IFNAR1 facilitates cellular immune responses including the activation of antiviral genes and modulation of cell proliferation. IFNAR1's role extends beyond immediate immune response influencing processes like cell differentiation and apoptosis.

Pathways

IFNAR1 is a participant in the JAK-STAT signaling pathway a significant pathway for transmitting cytokine signals. Upon interferon binding it activates the associated Janus kinases (JAKs) which in turn phosphorylate signal transducers and activators of transcription (STATs) specifically STAT1 and STAT2. This chain of events results in the transcription of interferon-stimulated genes that provide antiviral defenses and promote immune regulation. IFNAR1's engagement in these pathways makes it an integral part of immune system communication.

Associated diseases and disorders

IFNAR1 associates strongly with autoimmune diseases and viral infections. In lupus an autoimmune disorder dysregulation in interferon signaling involving IFNAR1 contributes to disease progression. Moreover in viral infections like hepatitis C the response of IFNAR1 to interferon therapies can influence treatment outcomes. Understanding these connections facilitates therapeutic strategies that target interferon pathways for improved disease management.
