SREBP1 (sterol-regulatory-element-binding protein 2) is a basic-helix-loop-helix-leucine zipper (bHLH-ZIP) transcription factor. It regulates sterol and cholesterol homeostasis by controlling enzymes involved in cholesterol synthesis and uptake, e.g. HMG-CoA. The SREBP1 antibody was used in fundamental studies to dissect SREBP1 domains and downstream signaling (1).

CXCR4 (C-X-C chemokine receptor type 4) is a member of the G-protein coupled receptor (GPCR1) family. It is expressed as a multipass membrane protein in several tissues where it acts as the receptor for the C-X-C chemokine CXCL12/SDF-1. This ligand increases intracellular calcium ion levels and enhances activation of the MAPK1/MAPK3 cascade.

Telomerase reverse transcriptase (TERT) is a ribonucleoprotein enzyme essential for eukaryotic chromosomal termini replication. It is a useful marker as it is active only in progenitor and most cancer cells, but inactive or (active at very low activity) in normal somatic cells.

8-hydroxyguanine is a form of oxidative DNA damage where free radicals cause G:C to T:A transversions within the backbone. In E. coli, three DNA repair enzymes exist to prevent the mutagenic effects of 8-hydroxyguanine mutations. One of these enzymes, Ogg1, was found to have both functional yeast (yOgg1) and human (hOgg1) homologues. These hOgg1 proteins efficiently release the 8-hydroxyguanine through cleavage.

The low density lipoprotein receptor coordinates the metabolism of cholesterol, an essential component of the mammalian cell plasma membranes. Study of this carefully balanced system has led to an enhanced understanding of cholesterol homeostasis at the cellular level. Receptor-mediated endocytosis (RME) is an important mechanism of metabolic regulation.

Sodium Potassium ATPase alpha 1 (ATP1A1) belongs to the P-type ATPase family and is the catalytic component of the active enzyme that catalyzes the hydrolysis of ATP coupled with exchange of sodium (Na+) and potassium (K+ ) ions across cellular plasma membranes. This creation of an electrochemical gradient comprised of Na+ and K+ ions provides the energy for nutrient active transport.

Human IgG is a component of the immune system that protects the body from infection. It is the most abundantly found antibody isotype within the circulatory system of the human body. All antibody isotypes contain two heavy chains and two light chains that are arranged in a Y-shape.

Carbohydrate response element binding protein (ChREBP) is a transcription factor involved in activating genes that encode enzymes of fatty acid biosynthesis in liver and adipose. It is believed to be a key controller of hepatic lipogenesis and has a partner MLX. One study used ChREBP antibodies to better understand the mechanisms of ChREBP transcription via promoter binding studies (1).

Prolyl-hydroxylase Domain Containing Protein 2 (PHD2) is one of four hydroxylase enzymes that function as oxygen sensors. They are responsible for the post-translational modification of hypoxia-inducible factor 1 alpha (HIF-1 alpha), a component of the transcriptional complex involved in oxygen homeostasis.

Fibronectin is a glycoprotein found in the extracellular matrix (ECM) that binds to integrins and other components of the ECM such as collagen and fibrin. Under normal physiological conditions, fibronectin is an important factor in cell adhesion, growth, differentiation, and migration.
