Experimental Verification for 1hyi » Early endosome antigen 1 (EEA1), monomer
This orientation is in agreement with studies of monomeric FYVE domain in micelles, which shows that exposed V21 and T22 residues are buried in the hydrophobic core (Kutateladze and Overduin 2001, Brunecky et al. 2005). However, the orientations of monomeric FYVE domains change when they form a dimer through an additional coiled-coil domain (see 1joc).

This orientation is in agreement with results of computational modeling of FYVE domains based on electrostatic interactions (Diraviyam et al. 2003). However, FYVE domain penetrates by ~15A deeper into the membrane according to our results: nonpolar residues are inserted in the membrane hydrocarbon core, not in the head group region.
