Activity summary

The ABCA1 protein also known as ATP-binding cassette transporter A1 plays an important role in lipid transport processes. It helps in the export of cholesterol and phospholipids to apolipoprotein A-I which is essential for high-density lipoprotein (HDL) formation. The ABCA1 molecular weight is approximately 220 kDa. This protein is widely expressed in various tissues including the liver lungs and intestines indicating its systemic role in lipid metabolism. Researchers often study ABCA1 using techniques like ABCA1 ELISA and H10 flow cytometry.

Biological function summary

ABCA1 functions as a cholesterol efflux pump in the cellular membrane. It facilitates the transfer of cholesterol to lipid-poor apolipoproteins such as apoA-I which then forms HDL particles. This active process helps maintain cellular cholesterol homeostasis and reduces cholesterol accumulation. ABCA1 is a critical component of the HDL synthesis pathway and does not form part of a larger protein complex acting more as an individual unit in this function.

Pathways

Many regulatory mechanisms control the activity of ABCA1. It plays a significant role in the reverse cholesterol transport pathway thereby promoting the movement of cholesterol away from peripheral tissues back to the liver for excretion. This pathway helps maintain systemic lipid balance. The LXR/RXR pathway regulates ABCA1 expression aligning it closely with other proteins such as LXR and ABCG1 which also deal with cholesterol metabolism.

Associated diseases and disorders

ABCA1 is intimately connected with atherosclerosis and Tangier disease. Dysfunction or mutations in the ABCA1 gene lead to impaired cholesterol efflux contributing to cholesterol build-up and atherosclerotic plaque formation. Tangier disease a rare genetic disorder arises from severe mutations in ABCA1 resulting in very low levels of HDL cholesterol. This protein's role in disease is often studied alongside proteins such as apoA-I and LDL receptors which influence cholesterol transportation and storage.
