Intracellular Protein Transport:

  • After transcription in the nucleus, the mRNA is translocated from the nucleus to the ribosomes attached to the rough endoplasmic reticulum (RER). The RER is the site of the biosynthesis of proteins.
  • The process of translation of mRNA sequence into amino acid sequence takes place in the RER.
  • The newly synthesized protein is then packaged into vesicles in the SER and transported to the Golgi complex.
  • The Golgi complex is the cell's packaging department. It packages proteins into transport vesicles for intra and extracellular protein transport.
