What does LRP1 do?

What does LRP1 do?

In the liver LRP1 is important for the removal of atherogenic lipoproteins (Chylomicron remnants, VLDL) and other proatherogenic ligands from the circulation. LRP1 has a cholesterol-independent role in atherosclerosis by modulating the activity and cellular localization of the PDGFR-β in vascular smooth muscle cells.

What is lrp3?

The NLRP3 gene provides instructions for making a protein called cryopyrin. Cryopyrin is a member of a family of proteins called intracellular “NOD-like” receptor (NLR) proteins. Cryopyrin is found mainly in white blood cells and in cartilage-forming cells (chondrocytes).

What is LDL receptor related protein?

Low-density lipoprotein receptor–related protein-1 (LRP1) is a large endocytic and signaling receptor that is widely expressed. In the liver, LRP1 plays an important role in regulating the plasma levels of blood coagulation factor VIII (fVIII) by mediating its uptake and subsequent degradation.

What is the LDLR gene?

The LDLR gene provides instructions for making a protein called the low-density lipoprotein receptor. This receptor binds to particles called low-density lipoproteins (LDLs), which are the primary carriers of cholesterol in the blood.

Where is NLRP3?

NLR family pyrin domain containing 3 (NLRP3) (previously known as NACHT, LRR and PYD domains-containing protein 3 [NALP3] and cryopyrin), is a protein that in humans is encoded by the NLRP3 gene located on the long arm of chromosome 1.

What is the NLRP3 Inflammasome?

The NLRP3 inflammasome is a multimeric protein complex that initiates an inflammatory form of cell death and triggers the release of proinflammatory cytokines IL-1β and IL-18.

What is LCAT biochemistry?

The LCAT gene provides instructions for making an enzyme called lecithin-cholesterol acyltransferase (LCAT). This enzyme plays a role in removing cholesterol from the blood and tissues.

What does LDLR stand for?

Summary. The low density lipoprotein receptor (LDLR) gene family consists of cell surface proteins involved in receptor-mediated endocytosis of specific ligands.

Where is LDLR?

The LDL receptor gene (LDLR) is found on chromosome 19 p13. 1-13.3 and spans 45 kb. The gene contains 18 exons constituting a 5.3-kb mRNA and encodes a single-chain glycoprotein that consists of 839 amino acids (Fig.

What activates NLRP3?

The NLRP3 inflammasome is activated by diverse stimuli, and multiple molecular and cellular events, including ionic flux, mitochondrial dysfunction, and the production of reactive oxygen species, and lysosomal damage have been shown to trigger its activation.

What is meant by inflammasome?

Definition. The inflammasome is a multiprotein intracellular complex that detects pathogenic microorganisms and sterile stressors, and that activates the highly pro-inflammatory cytokines interleukin-1b (IL-1b) and IL-18. Inflammasomes also induce a form of cell death termed pyroptosis.
