Product Specific Information
Highest antigen sequence indentity to the following orthologs: Mouse (59%), Rat (59%).
This recombinant protein control fragment may be used for blocking experiments with the corresponding antibody, PA5-84846. 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
Ninein is a component of subdistal appendages of the mother centriole, localized specifically in the pericentriolar matrix of the centrosome. It may be involved in microtubule minus-end capping, centriole positioning, and protein anchoring. Recent studies have shown that the microtubule nucleation and anchoring at the centrosome are independent processes linked by ninein function. At least five human ninein isoforms with divergent C-terminal domains and two mouse isoforms have been reported. Data indicates that the combined action of domains (C-terminal and N-terminal) might, in the absence of coiled coil region, be sufficient to localize ninein to the mother centriole. Microinjection of antibodies against ninein into metaphase HeLa cells can disrupt the reformation of tubular conformation of proteins within the centrosome following cell division, and consequently lead to dispersal of centrosomal material throughout the cytosol. MTOC (microtubule organizing center) function can be disrupted when anti-ninein antibodies are injected into postmitotic cells. Antibodies against ninein are present in sera from patients with autoimmune diseases that develop autoantibodies to centrosomal proteins.
