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.,FZD1,Epigenetics & Nuclear Signaling,Translation Control,Regulation of eIF4 and p70 S6 Kinase,Cancer,Signal Transduction,G protein signaling,G-Protein-Coupled Receptors(GPCR),mTOR Signaling Pathway,Cell Biology & Developmental Biology,Wnt/β-Catenin Signaling Pathway,ESC Pluripotency and Differentiation,Stem Cells,FZD1
