Frizzled-6(Fz-6) is a protein that in humans is encoded by the FZD6 gene. [5] [6] [7]
Members of the 'frizzled' gene family encode 7-transmembrane domain proteins that are receptors for WNT signaling proteins. The FZD6 protein contains a signal peptide, a cysteine-rich domain in the N-terminal extracellular region, and 7 transmembrane domains. However, unlike many other FZD family members, FDZ6 does not contain a C-terminal PDZ domain-binding motif. [7] Fz-6 is believed to be the receptor for the WNT4 ligand. [8]
Fz-6 has been shown to interact with secreted frizzled-related protein 1. [9]
The Wnt signaling pathways are a group of signal transduction pathways which begin with proteins that pass signals into a cell through cell surface receptors. The name Wnt is a portmanteau created from the names Wingless and Int-1. Wnt signaling pathways use either nearby cell-cell communication (paracrine) or same-cell communication (autocrine). They are highly evolutionarily conserved in animals, which means they are similar across animal species from fruit flies to humans.
Frzb is a Wnt-binding protein especially important in embryonic development. It is a competitor for the cell-surface G-protein receptor Frizzled.
Frizzled is a family of atypical G protein-coupled receptors that serve as receptors in the Wnt signaling pathway and other signaling pathways. When activated, Frizzled leads to activation of Dishevelled in the cytosol.
Axin-1 is a protein that in humans is encoded by the AXIN1 gene.
Lymphoid enhancer-binding factor 1 (LEF1) is a protein that in humans is encoded by the LEF1 gene. It is a member of T cell factor/lymphoid enhancer factor (TCF/LEF) family.
Proto-oncogene Wnt-1, or Proto-oncogene Int-1 homolog is a protein that in humans is encoded by the WNT1 gene.
Frizzled-2(Fz-2) is a protein that in humans is encoded by the FZD2 gene.
