Cholesterol-capturing domain Human meta-static lymph node (MLN) 64 is a late endosomal membrane protein, and carries this MENTAL (MLN64N-terminal) domain at its N-terminus. The domain is composed of four trans-membrane helices with three short intervening loops. The function of the domain is to capture cholesterol and pass it to the associated START domain pfam01852 for transfer to a cytosolic acceptor protein or membrane. In mammals, the MENTAL domain is involved in the localization of MLN64 and MENTHO in late endosomes, and also in homo-and of hetero-interactions of these two proteins.
