| Transport from the ER to
the Golgi |
|
|
|
| When
the protein is properly folded, COPII coated |
||
| vesicles
transport the proteins via the vesicular tubular |
||
| cluster (vtc) to
the cis-Golgi network. |

|
|

|
|
|
|
| • | The
COPII coating is removed |
|||||||||
| (Sar1
hydolyzes GTP) and the |
||||||||||
| vesicles
fuse with each other |
||||||||||
| to form
the vtc. |
||||||||||
| • | The vtc
is motored along |
|||||||||
| microtubules
that function like |
||||||||||
| railroad
tracks. |

| • | The vtc
fuses with the cis- |
|||||||||
| Golgi
network. |
