transcription in mammals. PeerJ 2:e270 DOI 10.7717/peerj.270 abstractPubMed ID24688849
||"Large scale surveys in mammalian tissue culture cells suggest that the protein expressed
at the median abundance is present at 8,000–16,000 molecules per cell and
that differences in mRNA expression between genes explain only 10–40% of the
differences in protein levels."
