分子别名(Synonym)

IFNAR2,IFNARB,IFNABR,IFN-R-2,IFN-alpha/beta receptor 2

表达区间及表达系统(Source)

Human IFNAR2, Fc Tag (IF2-H5255) is expressed from human 293 cells (HEK293). It contains AA Ile 27 - Lys 243 (Accession # P48551-2).

Predicted N-terminus: Ile 27

蛋白结构(Molecular Characterization)

Online(Ile 27 - Lys 243) P48551-2

This protein carries a human IgG1 Fc tag at the C-terminus.

The protein has a calculated MW of 51.4 kDa. The protein migrates as 66-90 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.

内毒素(Endotoxin)

Less than 1.0 EU per μg by the LAL method.

纯度(Purity)

>95% as determined by SDS-PAGE.

制剂(Formulation)

Lyophilized from 0.22 μm filtered solution in Tris with Glycine, Arginine and NaCl, pH7.5. Normally trehalose is added as protectant before lyophilization.

背景(Background)

Interferon alpha/beta receptor 2 (IFNAR2) is also known as IFN-alpha binding protein, IFN-alpha/beta receptor 2, Type I interferon receptor 2, IFNABR and IFNARB, which is a single-pass type I membrane protein and belongs to the type II cytokine receptor family. IFNAR2 can associate with IFNAR1 to form the type I interferon receptor. IFNAR2 is a receptor for interferons alpha and beta.IFNAR2 involves in IFN-mediated STAT1, STAT2 and STAT3 activation. Isoform 1 and isoform 2 of IFNAR2 are directly involved in signal transduction due to their association with the TYR kinase, JAK1. Isoform 3 of IFNAR2 is a potent inhibitor of type I IFN receptor activity.Genetic variations in IFNAR2 influence susceptibility to hepatitis B virus (HBV) infection.
