Cell Communication And Signalling: COP-I and COP-II (Retrograde And Anterograde Transport)!!!

COPII vs COPI finally explained ! If you mix ER to Golgi transport, this video is for you. In this video I explained: ✅ COP Full Form - Coat Protein Complex ✅ COPII - ER to Golgi (Anterograde) - Sar1, Sec23/24, Sec13/31, DxE signal ✅ COPI - Golgi to ER (Retrograde) - ARF1, Coatomer, KKXX / KDEL signal ✅ Tethering - TRAPPI, Rab1, Dsl1 complex ✅ SNARE - Bet1, Sed5, Ufe1, Use1, Sec20, Sec22 PDI- Protein Disulphide Isomerase TRICK: COPII = Sar1 = Sending OUT = ER to Golgi COPI = ARF1 = Returning BACK = Golgi to ER COPII makes it, COPI returns it, Clathrin eats it.
