FZD3
FZD3: A Crucial Receptor in Wnt Signaling and Disease
Description
FZD3 (frizzled class 3) is a G protein-coupled receptor (GPCR) that plays a pivotal role in the Wnt signaling pathway, a critical pathway involved in embryonic development, cell proliferation, and differentiation. FZD3 binds to Wnt proteins, initiating a cascade of intracellular events that regulate gene expression and cellular processes.
Associated Diseases
FZD3 mutations or dysregulation have been implicated in various human diseases, including:
- Colorectal cancer: FZD3 loss-of-function mutations are frequently observed in colorectal cancer, leading to reduced Wnt signaling and impaired cell growth control.
- Hepatocellular carcinoma: FZD3 overexpression promotes liver cancer cell proliferation and metastasis.
- Osteosarcoma: Aberrant FZD3 activation contributes to osteosarcoma development and progression.
- Neurological disorders: FZD3 mutations have been associated with autism spectrum disorder and schizophrenia.
- Congenital heart defects: Mutations in FZD3 can disrupt cardiac development, leading to heart defects such as atrial septal defects.
Did you Know ?
Approximately 15% of colorectal cancers harbor FZD3 mutations, highlighting the significant role of this gene in cancer development.
