Background: Limitin/IFN-zeta

Limitin is a secreted interferon (IFN)-like glycoprotein. It has antiviral activity and selectively inhibits B-lineage lymphoid-cell development both in vivo and in vitro, while having little effect on myelopoiesis or erythropoiesis. Mouse Limitin cDNA encodes a 182 amino acid (aa) residue precursor protein with an N-terminal 21 aa residue putative signal peptide. Limitin binds to the IFN-alpha / beta receptors and induces IFN regulatory factor-1. Mouse Limitin displays 32%, 26% and 30% amino acid identity with mouse IFN-alpha, mouse IFN-beta, and human IFN-omega, respectively.
