Relatively little is known about the in vivo functions of newly emerging genes, especially in metazoans. Although prior RNAi studies reported prevalent lethality among young gene knockdowns, our phylogenomic analyses reveal ...

Intercellular communication often involves phosphorylation of signal transduction proteins, including mitogen-activated protein kinases (MAPKs). Immunological detection of phosphorylated MAPK can be used to monitor ...
