Here we show that a virus-encoded transcription factor, viral mRNA, cellular RNA-binding protein heterodimer G3BP/Caprin-1 (p137), translation initiation factors eIF4E and eIF4G, and ribosomal proteins are concentrated in the same subdomains of cytoplasmic DNA factories
The single-stranded DNA- and RNA-binding protein, Puralpha, has been implicated in many biological processes, including control of transcription of multiple genes, initiation of DNA replication, and RNA transport and translation
RNA-binding proteins are involved in processes such as protection of RNAs from RNase degradation, prevention of ribosome binding to mRNA, control of formation of secondary structures of the mRNA that permit or prevent translation initiation, and termination/antitermination of transcription in response to external signals
d)The La autoantigen is an RNA-binding protein that is involved in initiation and termination of RNA polymerase III transcription
