Phenotypic Enhancement
A genetic interaction is inferred when mutation or overexpression of one gene results in enhancement of any phenotype (other than lethality/growth defect) associated with mutation or over expression of another gene.
Publication
Apolipoprotein E is the major physiological activator of lecithin-cholesterol acyltransferase (LCAT) on apolipoprotein B lipoproteins.
Our previous studies have indicated that lecithin-cholesterol acyltransferase (LCAT) contributes significantly to the apoB lipoprotein cholesteryl ester (CE) pool. Cholesterol esterification rate (CER) in apoA-I(-)(/)(-) apoE(-)(/)(-) mouse plasma was <7% that of C57Bl/6 (B6) mouse plasma, even though apoA-I(-)(/)(-) apoE(-)(/)(-) plasma retained (1)/(3) the amount of B6 LCAT activity. This suggested that lack of LCAT enzyme did not explain the ... [more]
Throughput
- Low Throughput
Ontology Terms
- phenotype: abnormal circulating cholesterol level (MP:0000180)
- tissue: blood plasma (BTO:0000131)
Additional Notes
- apoA1-/- apoe-/- double mutants have much reduced LCAT activity compared to either single mutant
