Previous GeneCards Identifiers for GPIHBP1 Gene
This gene encodes a capillary endothelial cell protein that facilitates the lipolytic processing of triglyceride-rich lipoproteins. The encoded protein is a glycosylphosphatidylinositol-anchored protein that is a member of the lymphocyte antigen 6 (Ly6) family. This protein plays a major role in transporting lipoprotein lipase (LPL) from the subendothelial spaces to the capillary lumen. Mutations in this gene are the cause of hyperlipoproteinemia, type 1D. Alternate splicing results in multiple transcript variants. [provided by RefSeq, Sep 2014]
GeneCards Summary for GPIHBP1 Gene
GPIHBP1 (Glycosylphosphatidylinositol Anchored High Density Lipoprotein Binding Protein 1) is a Protein Coding gene. Diseases associated with GPIHBP1 include Hyperlipoproteinemia, Type Id and Hyperlipoproteinemia, Type I. Among its related pathways are Lipoprotein metabolism and Signaling by GPCR. Gene Ontology (GO) annotations related to this gene include lipid binding and protein transmembrane transporter activity. An important paralog of this gene is LY6E.
UniProtKB/Swiss-Prot Summary for GPIHBP1 Gene
Mediates the transport of lipoprotein lipase LPL from the basolateral to the apical surface of endothelial cells in capillaries (By similarity). Anchors LPL on the surface of endothelial cells in the lumen of blood capillaries (By similarity). Protects LPL against loss of activity, and against ANGPTL4-mediated unfolding (PubMed:27929370, PubMed:29899144). Thereby, plays an important role in lipolytic processing of chylomicrons by LPL, triglyceride metabolism and lipid homeostasis (PubMed:19304573, PubMed:21314738). Binds chylomicrons and phospholipid particles that contain APOA5 (PubMed:17997385, PubMed:19304573). Binds high-density lipoprotein (HDL) and plays a role in the uptake of lipids from HDL (By similarity).
