Gene: IFNAR2 (interferon alpha and beta receptor subunit 2) Homo sapiens
Symbol: IFNAR2
Name: interferon alpha and beta receptor subunit 2
RGD ID: 1346107
Description: Exhibits protein kinase binding activity; type I interferon binding activity; and type I interferon receptor activity. Involved in defense response to other organism; response to interferon-alpha; and response to interferon-beta. Localizes to extracellular space and integral component of plasma membrane. Implicated in hepatitis B and immunodeficiency 45.
Type: protein-coding
RefSeq Status: REVIEWED
