Welcome to the Protein Journey Visualizer!

Master the cellular protein processing pathway through interactive learning

🧬

Welcome!

Discover how proteins travel through cellular organelles, undergo modifications, and reach their final destinations in this interactive journey.

🏭

Step 1: ER Synthesis

Proteins are created by ribosomes attached to the Endoplasmic Reticulum (ER)

The ER is like a protein factory where ribosomes act as assembly machines, reading genetic instructions to build proteins one amino acid at a time. This is where your protein's journey begins!

📦

Step 2: Create Vesicle

Drag the protein from the ER to package it into a transport vesicle

Think of vesicles as cellular delivery trucks. When you drag a protein away from the ER, it gets wrapped in membrane and becomes ready for transport to its next destination.

🚛

Step 3: Golgi Transport

Move the vesicle to the Golgi apparatus for processing

The Golgi apparatus is like a post office sorting center. Proteins arrive here to be modified, packaged, and labeled with their final destination addresses.

⚗️

Step 4: Protein Modifications

Apply modifications in the Golgi to prepare proteins for their roles

Glycosylation

Add sugar chains for cell recognition

P
Phosphorylation

Add phosphate groups for regulation

✂
Cleavage

Cut proteins to activate them

🎯

Step 5: Final Delivery

Package and deliver proteins to their final destinations

🧱
Cell Membrane

Proteins become part of the cell surface or are secreted outside

🗂️
Lysosome

Proteins help digest materials and recycle cellular components
