Relation of lung fatty acid binding protein to the biosynthesis of pulmonary phosphatidic acid and phosphatidylcholine. 1987

R U Haq, and F Tsao, and E Shrago

The activities of glycerophosphate and lysophosphatidylcholine (LPC) acyltransferases were determined using lung microsomes in the presence of lung fatty acid binding protein (FABP). The synthesis of phosphatidic acid (PA) was increased two- to fourfold in the presence of FABP as compared to albumin. Lung FABP did not increase the incorporation of palmitoyl CoA into phosphatidylcholine. The results indicate that FABP-bound fatty acyl CoA may be a preferred substrate for glycerophosphate acyltransferase.

D008243 1-Acylglycerophosphocholine O-Acyltransferase An enzyme localized predominantly within the plasma membrane of lymphocytes. It catalyzes the transfer of long-chain fatty acids, preferentially unsaturated fatty acids, to lysophosphatides with the formation of 1,2-diacylglycero-3-phosphocholine and CoA.

D008861 Microsomes Artifactual vesicles formed from the endoplasmic reticulum when cells are disrupted. They are isolated by differential centrifugation and are composed of three structural features: rough vesicles, smooth vesicles, and ribosomes. Numerous enzyme activities are associated with the microsomal fraction.

D009363 Neoplasm Proteins Proteins whose abnormal expression (gain or loss) are associated with the development, growth, or progression of NEOPLASMS. Some neoplasm proteins are tumor antigens (ANTIGENS, NEOPLASM), i.e. they induce an immune reaction to their tumor. Many neoplasm proteins have been characterized and are used as tumor markers (BIOMARKERS, TUMOR) when they are detectable in cells and body fluids as monitors for the presence or growth of tumors. Abnormal expression of ONCOGENE PROTEINS is involved in neoplastic transformation, whereas the loss of expression of TUMOR SUPPRESSOR PROTEINS is involved with the loss of growth control and progression of the neoplasm.
