The amino acid sequence that encodes DHCR7 is predicted to contain 475 amino acids, as well as several protein motifs . It contains multiple sterol reductase motifs, as would be expected given its function. It contains a potential sterol-sensing domain (SSD), whose function is unknown but thought to be necessary for binding sterol substrates. It also includes multiple sites of phosphorylation, including potential protein kinase C and tyrosine kinase sites (regulatory enzymes responsible for phosphorylation). The exact function of phosphorylating DHCR7 is yet unknown, but it is thought to be involved in the regulation of its activity.
