Cytosolic fatty acid binding proteins in rat placenta
Abstract
Placentae from 21 days pregnant rats were assayed for long-chain fatty acid binding activity. Oleate binding activity, associated with a low-molecular-weight protein fraction resembling liver fatty acid binding protein (FABP or 'Z' protein), could be demonstrated after removal of serum albumin by fractionation of the placental cytosol on Sephadex G-75. The fatty acid binding activity in the placenta was 2 to 4 per cent of the FABP activity present in rat liver.
