Abstract

The subject invention relates to the identification of several genes involved in the elongation of polyunsaturated acids (i.e., “elongases”) and to uses thereof. At least two of these genes are also involved in the elongation of monounsaturated fatty acids. In particular, elongase is utilized in the conversion of gamma linolenic acid (GLA) to dihomogama linolenic acid (DGLA) and in the conversion of DGLA or 20:4n-3 to eicosapentaenoic acid (EPA). DGLA may be utilized in the production of polyunsaturated fatty acids, such as arachiodonic acid (AA), docosahexaenoic acid (DHA), EPA, adrenic acid, ω6-docosapentaenoic acid or ω3-docosapentaenoic acid which may be added to pharmaceutical compositions, nutritional compositions, animal feeds, as well as other products such as cosmetics.
