User:DineshVannan/LDLR protein 8

This is a proposal for the project to improve and expand the article Low density lipoprotein receptor-related protein 8. This collaborative effort will be carried out over the course of this semester. Please feel free to post comments, make changes that would improve this page.

Dinesh Vannan, Neal Shah, and Eric Mlodzinski The work shall be split up as best seen fit by the group members. We shall be having weekly meetings to better collaborate out work.

Introduction
Low density lipoprotein receptor-related protein 8 (also known as ApoE2) is a cell-surface protein that is part of the LDL receptor family. These receptors regulate the transport of cholesterol, but have recently been seen to have functions beyond cholesterol metabolism. LRP 8 has been observed to play a role during the development of the mammalian brain, specifically affecting the layering of neurons in the cerebral cortex.

Structure
Apolipoprotein E (ApoE) is a 299 amino acid, 35 kDa glycoprotein constituent of lipoproteins in the plasma and brain. It is closely related to many other proteins in the LDLR family.

Function

 * cholesterol metabolism and in neuronal activity
 * closely associated with VLDLR
 * neuronal layering in development
 * plays a large role in delivery and clean up of cholesterol and plasma lipids

Signaling Pathways

 * Low density lipoprotein receptor-related protein 8 is involved in the signaling pathways of Dab1 and reelin.
 * The mechanism is incompletely understood.
