Singular Anti- RNA Virus-directed Proteins
Rayanade RJ, Banerjee K, Shirodkar MVN
Abstract
AIMS: To additionally purify and characterise the anti-RNA virus-directed protein termed p14. MATERIALS AND METHODS: Antiviral assays of p14 against RNA and DNA viruses were carried out and its antigenic similarities with chicken interferon (CIFN) were studied. HPLC-Reverse Phase of p14 was performed to further purify p14. RESULTS: p14 showed antiviral activity against RNA viruses only and not against DNA viruses. It was antigenically distinct from CIFN. Purification of p14 yielded three proteins with antiviral activity, which had different physico-chemical properties than those described for interferons. CONCLUSIONS: The data presented on the antiviral, immunological and physico-chemical properties, establish the unique nature of p14 vis-à-vis those of interferons.
