Molecular cloning and characterization of human Frizzled-4 on chromosome 11q14-q21.

The WNT receptors, encoded by the Frizzled genes, are implicated in a variety of cellular processes such as cell fate determination, cell polarity control, and malignant transformation. Human Frizzled-4 (FZD4) cDNAs have been cloned and characterized. FZD4 spans a total of 7392 nucleotides and encodes a 537-amino-acid protein with the N-terminal cysteine-rich domain, seven transmembrane domains, and the C-terminal S/T-X-V motif. The FZD4 mRNA of 7.7 kb in size were detected almost ubiquitously in normal human tissues and larger amounts in fetal kidney, adult heart, skeletal muscle, and ovary. Among cancer cell lines, the FZD4 mRNA level was higher in HeLa S3. The FZD4 gene has been mapped to human chromosome 11q14-q21. FZD4 is homologous to FZD9 and FZD10, and overall amino acid identity is as follows: FZD4 vs FZD9, 51.6%; FZD4 vs FZD10, 51.2%; FZD9 vs FZD10, 65.7%. FZD4 consists of two exons, while FZD9 and FZD10 consist of a single exon. FZD4 might belong to rather the independent FZD subfamily than the FZD9-FZD10 subfamily.[1]
