Designing a Western blot for IFNAR1? The guide has the expected band size, antibodies backed by real blot images, the controls to run alongside, and protocols taken from published papers.
Open the IFNAR1 Western Blot GuideFacts about Interferon alpha/beta receptor 1.
Type I interferon binding activates the JAK-STAT signaling cascade, and activates tyrosine phosphorylation of a number of proteins including JAKs, TYK2, STAT proteins and the IFNR alpha- and beta- subunits themselves (PubMed:7665574, PubMed:21854986). 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).

IFN receptors are present in all tissues and even on the surface of most IFN-resistant cells. Isoform 1, isoform 2 and isoform 3 are expressed in the IFN-alpha sensitive myeloma cell line U266B1. Isoform 2 and isoform 3 are expressed in the IFN-alpha resistant myeloma cell line U266R. Isoform 1 is not expressed in IFN-alpha resistant myeloma cell line U266R.
[Isoform 1]: Cell membrane; Single-pass type I membrane protein. Late endosome. Lysosome. Interferon binding triggers internalization of the receptor from the cell membrane into endosomes and then into lysosomes.
