, 1. Eiwit lokalisatie
Compartimentalisatie van de eukaryote cel

• Verschillende cel-processen vinden plaats op of in
verschillende membrane-enclosed organelles
• De verschillende organellen hebben specifieke
functies
• Verschillende eiwitten zijn nodig voor deze
processen/functies
• De juiste eiwitten moeten naar de juiste
organellen voor het goed functioneren van de cel

Verschillende compartimenten;

• (Ver)groot membraanoppervlak
• Scheiden van functies/processen
• Behoud van lage pH voor afscherming

De hoofdfuncties van de membrane-enclosed compartments van een eukaryote cel:

Organel Functie
Cytosol Bevat veel metabole routes
Nucleus Bevat genoom; DNA- en RNA-synthese
Endoplasmatisch reticulum Synthese van de meeste lipiden, synthese van eiwitten voor distributie naar veel
organellen en naar het plasmamembraan
Golgiapparaat Modificatie, sortering en verpakking van eiwitten en lipiden voor uitscheiding of
levering aan een ander organel
Lysosoom Intracellulaire degradatie
Endosoom Sorteren van endocytosed materiaal
Mitochondriën ATP-synthese door oxidatieve fosforylering
Chloroplasten (in planten) ATP-synthese en koolstoffixatie door oxidatieve fosforylering
Peroxisomen Oxidatie van giftige moleculen


Eiwit lokalisatie begint bij translatie

• Alle eiwitten worden gemaakt door ribosomen in het cytosol
• Een eiwit wat ergens heen moet heeft een signaal nodig dat zegt waar het naartoe moet
