A rhesus macaque rhadinovirus related to Kaposi's sarcoma-associated herpesvirus/human herpesvirus 8 encodes a functional homologue of interleukin-6.
The rhesus rhadinovirus strain 17577 (RRV strain 17577) genome is essentially colinear with human herpesvirus 8 (HHV8)/Kaposi's sarcoma-associated herpesvirus (KSHV) and encodes several analogous open reading frames (ORFs), including the homologue of cellular interleukin-6 (IL-6). To determine if the RRV IL-6-like ORF (RvIL-6) is biologically functional, it was expressed either transiently in C...
متن کاملNucleotide sequence of a functional cDNA for human thymidylate synthase.
We have determined the nucleotide sequence of a cDNA clone, pcHTS-1, encoding human thymidylate synthase (5,10-methylenetetrahydrofolate: dUMP C-methyltransferase, EC 2.1.1.45) which was previously isolated from a human fibroblast expressible cDNA library and functional in mouse cells. The 1.6 kilobase cDNA insert of pcHTS-1 encodes a subunit protein of 313 amino acid (Mr = 35,706) and its pred...
متن کاملIsolation of functional cDNA clones for human thymidylate synthase.
Thymidine auxotrophic mutants of mouse FM3A cells due to thymidylate synthase deficiency can be transformed into prototrophs by DNA-mediated gene transfer using total human DNA (Ayusawa, D., Shimizu, K., Koyama, H., Takeishi, K., and Seno, T. (1983) J. Biol. Chem. 258, 48-53). From one such transformed cell clone, cloned recombinant lambda phages containing DNA fragments were obtained recently ...
متن کاملtrans activation of the thymidylate synthase promoter of herpesvirus saimiri.
Herpesvirus saimiri has been shown to possess a thymidylate synthase (TS) gene that is unusual in its transcriptional regulation. Although TS is believed to be required for viral DNA synthesis, the TS-specific 2.5-kb mRNA was found most abundantly during the late phases of asynchronous virus replication in permissive cultures. To study the kinetics of gene activation, the TS promoter and regula...
متن کاملKaposi's sarcoma-associated herpesvirus encodes a functional cyclin.
Kaposi's sarcoma-associated herpesvirus (KSHV) (also called human herpesvirus 8) is consistently found in Kaposi's sarcoma lesions and in body-cavity-based lymphomas. A 17-kb KSHV lambda clone was obtained directly from a Kaposi's sarcoma lesion. DNA sequence analysis of this clone identified an open reading frame which has 32% amino acid identity and 53% similarity to the virus-encoded cyclin ...
