Highest antigen sequence indentity to the following orthologs: Mouse (82%), Rat (82%).
This recombinant protein control fragment may be used for blocking experiments with the corresponding antibody, PA5-58957. 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.
The product of this gene is a mitogen induced GTPase activating protein. It exhibits a specific GAP activity for Ras-related regulatory proteins Rap1 and Rap2, but not for Ran or other small GTPases. This protein may also hamper mitogen-induced cell cycle progression when abnormally or prematurely expressed. It is localized to the perinuclear region. Two alternatively spliced variants encoding the same isoform have been characterized to date.
