"In silico analysis identified SIDT1 and SIDT2 sharing identity and conserved cholesterol binding (CRAC) domains with C. elegans ChUP-1. Further evidence indicate that SIDT1 and SIDT2 not only do not transport RNA but they are involved in cholesterol transport. Single point mutations in the CRAC domains of both proteins prevent FRET between SIDT1 SIDT2 and dehydroergosterol and alter cholesterol transport."xsd:string
