General annotation (Comments)
| Function | Hydrolyzes 2-acetyl monoalkylglycerol ether, the penultimate precursor of the pathway for de novo synthesis of platelet-activating factor. May be responsible for cholesterol ester hydrolysis in macrophages, thereby contributing to the development of atherosclerosis. Also involved in organ detoxification by hydrolyzing exogenous organophosphorus compounds. May contribute to cancer pathogenesis by promoting tumor cell migration. Ref.5 |
| Subcellular location | Membrane; Single-pass type II membrane protein Probable. Microsome By similarity Ref.4. |
| Tissue specificity | Expressed in monocyte-derived macrophages. Up-regulated in invasive melanoma and breast carcinoma cell lines. Ref.4 Ref.6 |
| Post-translational modification | N-glycosylated. Ref.4 |
| Sequence similarities | Belongs to the 'GDXG' lipolytic enzyme family. |
| Sequence caution | The sequence AAH28734.2 differs from that shown. Reason: Erroneous initiation. The sequence AAH47588.2 differs from that shown. Reason: Erroneous initiation. The sequence BAA92601.1 differs from that shown. Reason: Erroneous initiation. The sequence BAH13028.1 differs from that shown. Reason: Erroneous initiation. The sequence BAH14142.1 differs from that shown. Reason: Erroneous initiation. The sequence BAH14802.1 differs from that shown. Reason: Erroneous initiation. |
