{{Short description|Mammalian protein found in Homo sapiens}} {{Infobox_gene}} '''Phospholipid transfer protein''' is a protein that in humans is encoded by the ''PLTP'' gene.
== Function ==
The protein encoded by this gene is one of at least two lipid transfer proteins found in human plasma. The encoded protein transfers phospholipids from triglyceride-rich lipoproteins to high density lipoprotein (HDL). In addition to regulating the size of HDL particles, this protein may be involved in cholesterol metabolism. At least two transcript variants encoding different isoforms have been found for this gene.<ref name="entrez">{{cite web | title = Entrez Gene: PLTP phospholipid transfer protein| url = https://www.ncbi.nlm.nih.gov/gene?Db=gene&Cmd=ShowDetailView&TermToSearch=5360}}</ref>
