Application

All Prestige Antibodies Powered by Atlas Antibodies are developed and validated by the Human Protein Atlas (HPA) project and as a result, are supported by the most extensive characterization in the industry. The Human Protein Atlas project can be subdivided into three efforts: Human Tissue Atlas, Cancer Atlas, and Human Cell Atlas. The antibodies that have been generated in support of the Tissue and Cancer Atlas projects have been tested by immunohistochemistry against hundreds of normal and disease tissues and through the recent efforts of the Human Cell Atlas project, many have been characterized by immunofluorescence to map the human proteome not only at the tissue level but now at the subcellular level. These images and the collection of this vast data set can be viewed on the Human Protein Atlas (HPA) site by clicking on the Image Gallery link. We also provide Prestige Antibodies^® protocols and other useful information.

Biochem/physiol Actions

STARD9 (steroidgenic acute regulatory protein-related lipid transfer (START) domain containing 9) in involved in cancer cell division. Studies suggest that during bipolar spindle assembly, this protein is responsible for the stabilization of pericentriolar material (PCM). This is achieved by associating PCM with the daughter centriole. The motor domain of STARD9 has both microtubule-binding and ATPase activity, which are essential for the localization of centriole. Cells with decreased STARD9 levels undergo rapid apoptosis. Cells treated with anti-cancer drug taxol show depleted STARD9 levels, and therefore, this protein might have potential as a chemotherapeutic target.

Features and Benefits

Prestige Antibodies^® are highly characterized and extensively validated antibodies with the added benefit of all available characterization data for each target being accessible via the Human Protein Atlas portal linked just below the product name at the top of this page. The uniqueness and low cross-reactivity of the Prestige Antibodies^® to other proteins are due to a thorough selection of antigen regions, affinity purification, and stringent selection. Prestige antigen controls are available for every corresponding Prestige Antibody and can be found in the linkage section.Every Prestige Antibody is tested in the following ways: IHC tissue array of 44 normal human tissues and 20 of the most common cancer type tissues. Protein array of 364 human recombinant protein fragments.

General description

STARD9 (steroidgenic acute regulatory protein-related lipid transfer (START) domain containing 9) belongs to the kinesin-3 family of proteins. It has three putative isoforms, with the largest composed of 4,614 amino acids and a predicted molecular weight of 506.7kDa. It has a START domain at its C-terminal, and also contains PX domain. It also shares the conserved motor and FHA domains with the other family members. The loop 12 of this protein contains a unique 26-amino acid insert. It is widely expressed in human organs such as in, brains, heart and skin. This gene is localized to human chromosome 15q15, and has a 9483bp coding sequence.
