anti-mouse Frizzled-4 monoclonal antibody Anti-Mouse 50 µg,Reliatech,103-M21

Wnt signaling is involved in variety of developmental processes including cell fate determination, cell polarity, tissue patterning and control of cell proliferation. Members of the Frizzled family of proteins serve as receptors for the Wnt signaling pathway. The founding member of this family was identified in Drosophila based on its role in tissue polarity in the adult cuticle and named for the disorganized appearance of bristle hairs on the mutant. Ten mammalian Frizzled genes have been identified to date. The predicted structure of Frizzled proteins is similar among all family members, containing a divergent Nterminal signal peptide, a highly conserved extracellular cysteinerich domain, a variablelength linker region, a sevenpass transmembrane domain, and a variablelength C-terminal tail. One of the most conserved regions of the Frizzled proteins is the extracellular cysteine-rich domain (CRD) which spans approximately 120 AA and contains 10 invariant cysteines. Mouse Frizzled-2 shows 100% amino acid identity to human and rat Frizzled2 in the CRD region. Frizzled2 expression is greater in embryonic than adult tissues, with heart, brain, lung, kidney and gut showing the highest levels.
