Ifnar2 - interferon (alpha and beta) receptor 2

Enables type I interferon receptor activity. Acts upstream of or within cell population proliferation and regulation of transcription by RNA polymerase II. Located in extracellular space. Is expressed in several structures, including genitourinary system; gut; hemolymphoid system; liver; and nervous system. Human ortholog(s) of this gene implicated in hepatitis B and immunodeficiency 45. Orthologous to human IFNAR2 (interferon alpha and beta receptor subunit 2).
