Members of this family are implicated in bringing cargo forward from the ER and binding to coat proteins by their cytoplasmic domains. This domain corresponds closely to the beta-strand rich GOLD domain described in [2]. The GOLD domain is always found combined with lipid- or membrane-association domains [2].
