I. Introduction

     aP2 is a highly functional carrier protein associated with fatty acids. aP2 stands for adipocyte protein 2 (the 2 signifies that there is another      adipocyte protein. aP1 is commonly associated with psoriasis).  2

 

     An adipocyte is a cell that specializes in the storage of fat and is commonly found in connective tissues.  3

 

     The protein is formally classified as a fatty acid binding protein and is also commonly called FABP4.  These are a family of 17 proteins      responsible for attaching to fatty acids 4 and carrying (hence the name carrier protein) them between cell organelles and cellular membranes.  4   

 

 

II. Structure

     aP2 is a crystalline structure protein   Studies on the structure both murine (mouse) and human
