Localization of Phe-13 and Phe-82 within the ARF molecule. A schematical drawing of ARF1, highlighting the location of phenylalanine at amino acid positions 13 and 82. The orientation of ARF1, relative to the membrane, is based on the requirement for stable membrane binding of a myristic acid residue, covalently bound to the N-terminal Gly-2 of ARF (11). The alkyl chain likely functions as an anchor for binding of ARF to the membranes (11, 12)
