Abstract
Polypeptides are obtained, for example, via expression of encoding cDNA sequences, that have the activity of the enzyme lysophosphatidic acid acyltransferase (LPAAT), also known as 1-acyl sn-glycerol-3-phosphate acyltransferase.
Claims2
A method for screening one or more compounds to determine whether said one or more compounds increases or decreases lysophosphatidic acid acyltransferase (LPAAT) activity, comprising:
- (a) contacting a polypeptide, wherein said polypeptide is an isolated polypeptide having LPAAT activity, comprising the amino acid sequence of SEQ ID NO:13, SEQ ID NO:15, SEQ ID NO:17, or an enzymatically active fragment thereof, with one or more substrates for said polypeptide and said one or more compounds;
- (b) measuring whether the LPAAT activity of said polypeptide is increased or decreased by said one or more compounds;
- and
- (c) comparing the LPAAT activity in the presence of said one or more compounds with the LPAAT activity in the absence of said one or more compounds, wherein an increase or decrease in LPAAT activity in the presence of said one or more compounds is indicative of a compound that increases or decreases LPAAT activity, respectively.
