Beta Actin Antibodies: Much More than a Loading Control

Beta-actin belongs to a large family of highly conserved structural cell proteins that regulate cell motility, structure, and integrity. Beta-actin is expressed in all eukaryotic cells making it the ideal internal quantitative control for protein comparative assays. This feature has made it uniquely a historical and heavily-utilized standard, as the public record of scientific publication literature can attest to.

SREBP: Gatekeeper of Cholesterol Homeostasis

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).

SREBP2: From Cholesterol Homeostasis to Cancer Invasion

ABCA1 Expression is Down-Regulated by SREBP microRNA

The ABCA1 (ATP-binding cassette transporter-A1) gene encodes a transmembrane protein, which plays a major role in phospholipid homeostasis by regulating cholesterol efflux from the cell. ABCA1 antibody studies have shown ABCA1 expression is up/down regulated by the transcription factors LXR and SREBP2 respectively.

ABCA1 Mutations: A Risk Factor in Atherosclerosis Related Strokes

The ATP Binding Cassette Transporter (ABCA1) gene encodes the cholesterol regulatory efflux protein, which plays a key role in lipid metabolism. ABCA1 antibody products are an important part of any antibody catalog covering atherosclerosis disease research.
