This liquid constitutes about half of the typical animal cell
What is the cytosol?
This is the major phospholipid of the ER
what is phosphatidylcholine?
The direction Exocytosis moves with respect to the cytosol
What is out of?
The number of membranes the mitochondria has
What is two?
The compartment that the vesicle leaves from is the...
What is the donor?
A part of the cell that is capable of disassembling, being flexible, and storing material for a brief period and that does not contain a membrane
What are biomolecular condensates?
This enzyme allows for the transport of phospholipids to the opposite side of the membrane
What is a flippase?
This is the three-legged structure of clathrin
What is a triskelion?
small vesicle that is derived from fragmented ER produced when cells are homogenized
what is a microsome?
a class of short noncoding RNAs that regulate gene expression
what is miRNA
The enzyme that adds GPI anchor to proteins and removes hydrophobic regions and is found in the ER membrane
What is transamidase enzyme?
This complex is responsible for importing proteins across the outer mitochondrial membrane
What is the Tom complex?
These proteins facilitate membrane bending throughout the cell, including in the clathrin pathway
What are BAR-domain proteins?
A sequence of RNA that can be used to silence target gene expression
what are shRNAs ?
The family of proteins that catalyzes the membrane fusion reactions in membrane transport
what are SNARE proteins?
Proteins utilize a mechanism that is membrane-enclosed, includes a cargo carrying intermediate, and fuses with a membrane for cargo exchange
What is Vesicular transport?
This is the mesh layer of the nuclear envelope that is made of filaments responsible for anchoring
What is the nuclear lamina?
The process by which cells take in fluids
What is pinocytosis?
a membrane protein that transports 2 different ions or small molecules across a membrane in opposite directions
Vesicles where molecules can be retrieved from the golgi and returned to the ER
what is COPI
An increase in the size of the ER and an increase in transcription of protein folding genes due to a cluster of misfolded proteins in the ER
What is unfolded protein response?
This enzyme is the molecular switch that aids the transportation of proteins across the nuclear membrane
What is the GTPase Ran?
This C terminal sequence of four amino acids marks soluble ER resident proteins for retrieval in the event that they escape.
What is KDEL?
The protein translocator that forms a water-filled pore in the ER membrane, allowing passage of a polypeptide chain as it is being synthesized by membrane-bound ribosomes.
what is sec61 complex
Protein that is attached to one face of a membrane by non-covalent interactions with other membrane proteins
what is a peripheral membrane protein?
