What two types of receptors are involved in receptor mediated endocytosis, and what types of substances are their “ligands”? What function does receptor mediated endocytosis play for each type of receptor?

Expert Solution

In receptor mediated endocytosis , clathrin coated receptors are inloved. These receptors are coated with claritin protein towards the cytosol.
Two important ligand which use these receptors are insulin, iron and LDL.
This mechanism is used for specific uptake of certain substance required by cells. Eg LDL receptor for uptake of LDL cholesterol, iron via transferrin.

Receptor-mediated endocytosis could involve of the processes described below EXCEPT...... A. hormones being secreted outside the cell. B. the uptake of excess cholesterol by cells in blood tissue. C, receptor proteins to bind to specific molecules. D. a coated vesicle pit forms which then eventually becomes a coated vesicle inside the the cell. E. a type of bulk transport.

Cultured liver hepatocytes are convenient for studying both exocytosis and receptor-mediated, clathrin-dependent endocytosis. As part of an advanced laboratory in cell biology, students are required to perform mutation studies on cultured liver hepatocytes to generate data that supports the proposed mechanism of receptor-mediated, clathrin-dependent endocytosis. Liver hepatocytes are cultured, mutagenized, and screened for defective receptor-mediated endocytosis. In order to distinguish unique mutants from one another, the students must design a series of experiments to distinguish between mutants that have the...

What do LDL receptor (LDLR) cytoplasmic domain mutations that cause familial hypercholesterolemia reveal about the receptor-mediated endocytosis (RME) pathway? Based on your knowledge of the entire endocytic process of LDL, are there other proteins in the pathway that if mutated might cause hypercholesterolemia? Explain how and why a mutation in a different protein in the pathway could cause disease. For a person who is homozygous for the NPXY mutation in their LDLR, can you think of a way to fix...
