25934, A NOVEL FATTY ACID DESATURASE AND USES THEREFOR

摘要

The invention provides isolated nucleic acids molecules, designated 25934 nucleic acid molecules, which encode a novel desaturase family member. The invention also provides antisense nucleic acid molecules, recombinant expression vectors containing 25934 nucleic acid molecules, host cells into which the expression vectors have been introduced, and nonhuman transgenic animals in which a 25934 gene has been introduced or disrupted. The invention still further provides isolated 25934 proteins, fusion proteins, antigenic peptides and anti-25934 antibodies. Diagnostic methods utilizing compositions of the invention are also provided. The invention also provides methods for modulating fatty acid metabolism utilizing the compositions of the invention. Accordingly, methods of treating, preventing and/or diagnosing cardiovascular disorders, such atherosclerosis, hypertriglyceridemia, hypercholesterolemia, and hyperlipidemia, are disclosed.
