Viral interferon regulatory factor 1 of Kaposi's sarcoma-associated herpesvirus interacts with a cell death regulator, GRIM19, and inhibits interferon/retinoic acid-induced cell death.

Abstract

Kaposi's sarcoma-associated herpesvirus (KSHV) plays a significant role in the development of Kaposi's sarcoma, primary effusion lymphoma, and some forms of multicentric Castleman's disease.
