MeSH definition : Proteins that are coded by immediate-early genes, in the absence of de novo protein
synthesis. The term was originally used exclusively for viral regulatory proteins
that were synthesized just after viral integration into the host cell. It is also
used to describe cellular proteins which are synthesized immediately after the resting
cell is stimulated by extracellular signals.;
