Product Specific Information
Highest antigen sequence indentity to the following orthologs: Mouse (72%), Rat (72%).
This recombinant protein control fragment may be used for blocking experiments with the corresponding antibody, PA5-60462. In IHC/ICC and WB experiments, we recommend a 100x molar excess of the protein fragment control based on the concentration and the molecular weight. Pre-incubate the antibody-protein control fragment mixture for 30 min at room temperature.
Target Information
CRB2 (Crumbs homolog 2), like its homologs CRB1 and CRB3, is similar to the Drosophila crumbs protein and is expressed in retina, brain and kidney. Along with other proteins, the Crumbs proteins form a complex that help set up cell polarity in developing neuroepithelial cells. At the onset of neural specification, embryonic stem cells (ESCs) upregulate CRB2, which then localizes apically in neural rosettes. Gain- and loss-of-function studies of CRB2 have shown that CRB2 is essential for the stabilization of other polarity proteins. Unlike CRB1, mutations in CRB2 do not appear to play a role in retinitis pigmentosa or in Leber congenital amaurosis.
