Gene: Ifna2 (interferon alpha 2) Rattus norvegicus
No known orthologs.
Symbol: Ifna2
Name: interferon alpha 2
RGD ID: 1311425
Description: Predicted to enable cytokine activity and type I interferon receptor binding activity. Predicted to be involved in several processes, including B cell activation; lymphocyte activation involved in immune response; and positive regulation of peptidyl-serine phosphorylation of STAT protein. Predicted to be active in extracellular space. Human ortholog(s) of this gene implicated in Crimean-Congo hemorrhagic fever; common cold; hepatitis B; liver disease (multiple); and sarcoidosis. Orthologous to several human genes including IFNA1 (interferon alpha 1); IFNA10 (interferon alpha 10); and IFNA13 (interferon alpha 13); PARTICIPATES IN autoimmune thyroiditis pathway; autophagy pathway; cytokine mediated signaling pathway; INTERACTS WITH 2-acetamidofluorene; ammonium chloride; N-nitrosodiethylamine.
Type: protein-coding
RefSeq Status: VALIDATED
Previously known as: If1ai9; interferon 1ai9; interferon alpha family, gene 2; LOC298213
