Traditional western blot evaluation of wild-type mice uncovered high appearance of LPIAT1 in the mind among the tissue tested (Body 1C). In the fetal human brain, appearance of LPIAT1 was seen in the cerebral cortex (Body 1D), the CA locations as well as the dentate gyrus from the hippocampus (Body 1E), the exterior plexiform level as well as the mitral cell level from the olfactory light bulb (Body 1F), as well as the granular cell level from the cerebellum (Body 1G). On the other hand, LPIAT1 protein had not been detected in tissue from mice (Body 1, CCG). LPIAT activity with AA-CoA as an acyl donor was nearly absent in the membranes of the mind (Body 1H), but acyltransferase actions toward various other lysophospholipids weren’t changed (Body 1I). AA-CoA:LPIAT activity was undetectable in the membranes from the liver organ also, kidney, and testis from mice (Body 1H). These data suggest that LPIAT1 may be the predominant enzyme that catalyzes the incorporation of AA into lysoPI in mice.

As proven previously (Palmer, 1986 ), acyltransferase activity with AA-CoA as an acyl donor toward lysoPI4P or lysoPI(4,5)P2 was nearly undetectable in the membranes of the mind from wild-type mice weighed against the experience toward lysoPI (Body 3A). Overexpression of LPIAT1 didn’t raise the acyltransferase activity toward lysoPI4P or lysoPI(4,5)P2 (Body 3B). These data suggest that AA-containing PI phosphates aren’t produced by incorporation of AA into lysoPI phosphates.
