WebSep 9, 2015 · Sustained ERK-RSK activation and substrates during KSHV lytic replication. Extracellular mitogen-like stimuli or glycoproteins of KSHV virion trigger transient ERK-RSK activation to induce expression of the IE genes RTA, K8 and ORF45 during the IE stage of primary infection or reactivation from latency. Consequently, ORF45 and other viral ... In molecular biology, ribosomal s6 kinase (rsk) is a family of protein kinases involved in signal transduction. There are two subfamilies of rsk, p90 , also known as MAPK-activated protein kinase-1 (MAPKAP-K1), and p70 , also known as S6-H1 Kinase or simply S6 Kinase. There are three variants of p90 in humans, rsk 1-3. Rsks are serine/threonine kinases and are activated by the MAPK/ERK p… refoundstore.ca
