Anti-ABCA1 (ATP-binding Cassette Sub-family A Member 1, ATP-binding Cassette Transporter 1, ABC-1, A

ABCA1 is a 240-280kD member of the ABCA family, ABC transporter superfamily of molecules. It is widely expressed, particularly by macrophages, where it participates in the transport of lipid across cell membranes. Once transported, it is passed on to tethered apoA-I to form HDL. Human ABCA1 is 2261aa in length. It has up to 15 transmembrane segments with beginning and ending cytoplasmic domains and a large cytoplasmic central region. ABC transporters are found between aa899-1311 and aa1912-2144, aa2216-2221 are essential for lipid transport, and two intramolecular disulfide bonds are required for activity aa75-309 and aa1463/1465-1477). There are three potential isoform variants. One possesses an alternative start site at 61aa, while two others contain 12aa and 123aa substitutions for aa241-2261, respectively. Over aa1248-1350, human ABCA1 shares 97% aa identity with mouse ABCA1. Applications: Suitable for use in Flow Cytometry and Immunocytochemistry. Other applications not tested.
