Protein transport

Flussdiagrammknoten

• TranscriptionCreation of mRNA in the nucleus

• TranslationCreation of proteins on the ribosome

• More detail on protein synthesis in other resources

• Protein moves through rough ER, developing its 3D stucture

• Protein formed moves into rER and travel through membrane bound sacs of the rER

• When protein reaches the end of the membrane bound sac, vesicles are pinched off the end of the rER.

• Vesicles form to fuse flattened sacs of the golgi apparatus

• Transport vesicles move the 3D protein to the Goglgi apparatus.

• Proteins move through the golgi and are modified.

• Vesicles containing the modified protein are pinched off the golgi

• Vesicles fuse with cell membrane and proteins are released.

• Exocytosis
