frizzled基因家族成员编码7-跨膜结构域蛋白，它们是Wnt信号蛋白的受体FZD1蛋白包含一个信号肽、N端胞外区富含半胱氨酸的结构域、7个跨膜结构域和一个C端PDZ结构域结合基序FZD1转录本在各种组织中表达。[由RefSeq提供，2008年7月]
Members of the 'frizzled' gene family encode 7-transmembrane domain proteins that are receptors for Wnt signaling proteins. The FZD1 protein contains a signal peptide, a cysteine-rich domain in the N-terminal extracellular region, 7 transmembrane domains, and a C-terminal PDZ domain-binding motif. The FZD1 transcript is expressed in various tissues. [provided by RefSeq, Jul 2008]
