Kaposi's sarcoma-associated herpes virus (KSHV) belongs to the gamma-herpesvirus subfamily of the Herpes viridae family and has been closely linked to the Kaposi's sarcoma, primary effusion lymphoma (PEL) and multicentric Castleman's disease. The genome of KSHV is 165-170 kb and contains at least 88 open reading frames. ORF45 protein encoded by an immediate-early gene in the KSHV genome is characterized as a phosphorylated protein, and it is localized in the cytoplasm of infected cells. Studies have shown that ORF45 Protein interacted with cellular IRF-7 and blocked virus-mediated phosphorylation and nuclear translocation of IRF-7. In consequence, ORF45 efficiently inhibited virus-induced production of type I IFN. Zhu et al (2003) reported that the ORF45 Protein was associated with purified virions.

Based on the analysis of the mRNA sequence, ORF45 is expected to encode a protein of 407 amino acids with a molecular mass of about 50 kDa. However, ORF45 was displayed as a diffuse band at the position of 78 kDa on a Western blot after SDS-PAGE. This observation implied that ORF45 might be highly post-translationally modified, resulting in its reduced mobility in denaturing SDS-PAGE. A survey of the primary amino acid sequence of ORF45 revealed multiple potential sites of phosphorylation, including a serine-rich region and other consensus sites for phosphorylation by the serine/threonine kinase, casein kinase II, and protein kinase C (Zhu & Yuan, 2003).
