Frizzled-8(Fz-8) is a protein that in humans is encoded by the FZD8 gene. [5] [6]
This intronless gene is a member of the frizzled gene family. Members of this family encode seven-transmembrane domain proteins that are receptors for the Wingless type MMTV integration site family of signaling proteins. Most frizzled receptors are coupled to the beta-catenin canonical signaling pathway. This gene is highly expressed in two human cancer cell lines, indicating that it may play a role in several types of cancer. The crystal structure of the extracellular cysteine-rich domain of a similar mouse protein has been determined. [6]
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.
The related to receptor tyrosine kinase (RYK) gene encodes the protein Ryk.
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.
Frizzled-5(Fz-5) is a protein that in humans is encoded by the FZD5 gene.
Frizzled-3(Fz-3) is a protein that in humans is encoded by the FZD3 gene.
Frizzled-1(Fz-1) is a protein that in humans is encoded by the FZD1 gene.
Frizzled-6(Fz-6) is a protein that in humans is encoded by the FZD6 gene.
Frizzled-7(Fd-7) is a protein that in humans is encoded by the FZD7 gene.
Frizzled-9(Fz-9) is a protein that in humans is encoded by the FZD9 gene. Fz-9 has also been designated as CD349.
Frizzled-10(Fz-10) is a protein that in humans is encoded by the FZD10 gene. Fz-10 has also been designated as CD350.
Probable G-protein coupled receptor 124 is a protein that in humans is encoded by the GPR124 gene. It is a member of the adhesion-GPCR family of receptors. Family members are characterized by an extended extracellular region with a variable number of protein domains coupled to a TM7 domain via a domain known as the GPCR-Autoproteolysis INducing (GAIN) domain.
Frizzled-4(Fz-4) is a protein that in humans is encoded by the FZD4 gene. Fz-4 has also been designated as CD344.
Leucine-rich repeat-containing G-protein coupled receptor 5 (LGR5) also known as G-protein coupled receptor 49 (GPR49) or G-protein coupled receptor 67 (GPR67) is a protein that in humans is encoded by the LGR5 gene. It is a member of GPCR class A receptor proteins. R-spondin proteins are the biological ligands of LGR5. LGR5 is expressed across a diverse range of tissue such as in the muscle, placenta, spinal cord and brain and particularly as a biomarker of adult stem cells in certain tissues.
Low-density lipoprotein receptor-related protein 5 is a protein that in humans is encoded by the LRP5 gene. LRP5 is a key component of the LRP5/LRP6/Frizzled co-receptor group that is involved in canonical Wnt pathway. Mutations in LRP5 can lead to considerable changes in bone mass. A loss-of-function mutation causes osteoporosis pseudoglioma syndrome with a decrease in bone mass, while a gain-of-function mutation causes drastic increases in bone mass.
Dickkopf-related protein 1 is a protein that in humans is encoded by the DKK1 gene.
Secreted frizzled-related protein 1, also known as SFRP1, is a protein which in humans is encoded by the SFRP1 gene.
Low-density lipoprotein receptor-related protein 6 is a protein that in humans is encoded by the LRP6 gene. LRP6 is a key component of the LRP5/LRP6/Frizzled co-receptor group that is involved in canonical Wnt pathway.
Secreted frizzled-related protein 2 is a protein that in humans is encoded by the SFRP2 gene. This gene encodes a member of the SFRP family that contains a cysteine-rich domain homologous to the putative Wnt-binding site of Frizzled proteins. SFRPs act as soluble modulators of Wnt signaling. Methylation of this gene is a potential marker for the presence of colorectal cancer.
Secreted frizzled-related protein 5 is a protein that in humans is encoded by the SFRP5 gene.
