概述

Interferon-Omega(IFN-ω)coded by IFNW1 gene in human,is a number of the type I interferon family,which includes IFN-α,IFN-β,and IFN-ω.The IFNAR-1/IFNAR-2 receptor complex can help with the signal transduction,followed the antiviral or the antiproliferative actions.IFN-ω is derived from IFN-α/β and share 75%sequence with IFN-α.It has two intramolecular disulfide bonds which are crucial for activities.Mire-Sluis et al have described bioassays for IFN-α,IFN-β,and IFN-ω that exploit the ability of these factors to inhibit proliferation of TF-1 cells induced by GM-CSF.The bioassays can be used also with Epo and TF-1 cells,or Epo and Epo-transfected UT-7 cells.
