RNAmetasome network for macromolecule biogenesis in human cells.

ABSTRACT: RNA plays a central role in macromolecule biogenesis for various pathways, such as gene expression, ribosome biogenesis, and chromatin remodeling. However, RNA must be converted from its nascent to functional forms for that role. Here, we describe a large RNA metabolic network (RNAmetasome network) for macromolecule biogenesis in human cells. In HEK293T, the network consists of proteins responsible for gene expression, splicing, ribosome biogenesis, chromatin remodeling, and cell cycle. Reciprocal immunoprecipitations show that MKI67, GNL2, MDN1, and ELMSAN1 are core proteins of the network, and knockdown of either MKI67 or GNL2 affects the state of the other protein, MDN1, and some other network members. Furthermore, GNL2 knockdown retards cell proliferation. Several proteins of the RNAme
