Topic 12 Intracellular Organization and Protein Sorting I
This intracellular compartment makes up the most volume in the cell.
What is the Cytosol?
This is how transport is facilitated leaving the ER.
What is Vesicular transport?
Proteins that function solely to link two or more different proteins together in an intracellular signaling pathways
What are adaptor proteins?
This membrane-bound organelle is specialized for carrying out certain oxidation reactions.
What is the Peroxisome?
These enzymes catalyze the transfer of specific phospholipids from one monolayer to the other.
What are flippases?
Organelle surrounded by double membrane that contains engulfed cytoplasmic cargo in the initial stages of autophagy
What is an autophagosome?
This chaperone protein is involved in post-translational protein translocation to the ER.
What is BiP?
These proteins are used for transport to chloroplast.
What is a thylakoid signal sequence?
Hypothesis that Golgi has polarization with how molecules move between cisterna. Cisterna are dynamic structures that mature, early to late by acquiring and losing specific golgi-resident proteins as they move through the stacks with cargo
What is the cisternal maturation mechanism?
These two ER resident carbohydrate binding lectins act as chaperones for unfolded glycoproteins.
What is Calnexin and Calreticulin?
Organelle in which oxidase and catalase reactions take place.
What are peroxisomes?
Transport pathway of proteins directly to the cell's surface via the non-selective constitutive secretory pathway. It does NOT require a signal
What is the default pathway?
These two nuclear components serve as scaffold for condensate formation. When mixed together these two nuclear components partition, resembling their separation within the nucleolus.
What is fibrillarin and nucleophosmin?
Protein translocation complex in the mitochondria that uses energy from the membrane potential.
What is the TIM23 protein complex?
The low pH in the endosome and removal of the phosphate from the M6P group
What causes transport of hydrolases to be unidirectional?
