Description

The recombinant mouse phospholipid transfer protein (Pltp) is generated by introducing the gene encoding the full-length mature Pltp protein (18-493aa) and an N-terminal 6xHis-tag gene into a plasmid. Subsequently, the recombinant plasmid is transferred into E.coli cells to enable the production of the protein. Following expression, the recombinant Pltp protein is extracted and purified from the lysate of these cells. The purity of the purified protein exceeds 90%, as determined by SDS-PAGE analysis. On the gel, the recombinant Pltp protein is visualized as a band with an approximate molecular weight of 57 kDa.

Target Background

Function

Mediates the transfer of phospholipids and free cholesterol from triglyceride-rich lipoproteins (low density lipoproteins or LDL and very low density lipoproteins or VLDL) into high-density lipoproteins (HDL) as well as the exchange of phospholipids between triglyceride-rich lipoproteins themselves. Facilitates the transfer of a spectrum of different lipid molecules, including sphingomyelin, phosphatidylcholine, phosphatidylinositol, phosphatidylglycerol, and phosphatidyl ethanolamine. Plays an important role in HDL remodeling which involves modulating the size and composition of HDL. Also plays a key role in the uptake of cholesterol from peripheral cells and tissues that is subsequently transported to the liver for degradation and excretion. Two distinct forms of PLTP exist in plasma: an active form that can transfer phosphatidylcholine from phospholipid vesicles to HDL, and an inactive form that lacks this capability.
