Background Information
Frizzled class receptor 7 (Frizzled 7, also known as FZD7) is a member of the superfamily of G protein-coupled receptor proteins that act as receptors in the Wnt signaling pathway. Frizzled 7 plays a role in development, stem cell renewal, and differentiation and has been implicated in the progression of various cancers.
What is the molecular weight of Frizzled 7? Is Frizzled 7 post-translationally modified?
The molecular size of Frizzled 7 is ~63 kDa, which represents the mature N-glycosylated species (PMID: 25274627). Frizzled 7 can form homodimers and heterodimers with other Frizzled family members (PMID: 14688793).
What is the subcellular localization of Frizzled 7?
Frizzled 7 is a seven-pass transmembrane protein that is present at the plasma membrane. In endothelial cells, it predominantly locates to cell-cell junctions (PMID: 24866384). Frizzled 7 has a cleavage site for calpain-1 protease in its C-terminus that regulates its activity and plasma membrane turnover (PMID: 17716656).
What is the tissue expression pattern of Frizzled 7?
Frizzled 7 is expressed at high levels in adult skeletal muscles and in fetal kidneys, but is also present in fetal lung, adult heart, brain, and placenta (PMID: 9813155). Frizzled 7 expression is increased in various cancer types, including melanoma, hepatocellular carcinoma, lung, esophageal, gastric, and colon cancers.

Reviews
What customers say
Users report positive experiences with this antibody across multiple applications. For Western Blot and Immunoprecipitation on mouse brain tissue, one reviewer rated it 4/5, noting it performs well but occasionally produces unspecific bands. Two reviewers used it for Immunofluorescence—one on fibroblasts (5/5) and another on small intestine sections (5/5)—both reporting good signal quality. Overall, the antibody is well-received, with most users satisfied with its performance, though slight non-specific binding was noted in one WB/IP application.
The reviews below have been submitted by verified Proteintech customers who received an incentive for providing their feedback.
