ANGPTL3 Antibody – Rabbit Polyclonal

The protein encoded by this gene is a member of the angiopoietin-like family of secreted factors. It is predominantly expressed in the liver, and has the characteristic structure of angiopoietins, consisting of a signal peptide, N-terminal coiled-coil domain and the C-terminal fibrinogen (FBN)-like domain. The FBN-like domain in angiopoietin-like 3 protein was shown to bind alpha-5/beta-3 integrins, and this binding induced endothelial cell adhesion and migration. This protein may also play a role in the regulation of angiogenesis. [provided by RefSeq]

ANGPTL3: Defects in ANGPTL3 are the cause of familial hypobetalipoproteinemia type 2 (FHBL2); also called combined hypobetalipoproteinemia familial. FHBL2 is a disorder of lipid metabolism characterized by less than 5th percentile age- and sex-specific levels of low density lipoproteins, and dietary fat malabsorption. Affected individuals present with combined hypolipidemia, consisting of extremely low plasma levels of LDL cholesterol, HDL cholesterol, and triglycerides.
