IFNAR2（interferon alpha and beta receptor subunit 2），癌症关联基因，基因ID：3455，这个基因编码的蛋白质是一种I型膜蛋白，形成α和β干扰素受体的两条链之一。受体的结合和激活刺激Janus蛋白激酶，进而磷酸化一些蛋白质，包括STAT1和STAT2已发现该基因至少编码两种不同亚型的多个转录变体。[由RefSeq提供，2008年7月]The protein encoded by this gene is a type I membrane protein that forms one of the two chains of a receptor for interferons alpha and beta. Binding and activation of the receptor stimulates Janus protein kinases， which in turn phosphorylate several proteins， including STAT1 and STAT2. Multiple transcript variants encoding at least two different isoforms have been found for this gene. [provided by RefSeq， Jul 2008]。
