General description

NUMA1 (Nuclear mitotic apparatus protein 1) is a coiled-coil protein consisting of a globular head and tail domains, which is linked by a large coiled-coil region. Its tail domain is composed of microtubule, LGN binding sites, and a nuclear localization signal (NLS).

Immunogen

Nuclear mitotic apparatus protein 1 recombinant protein epitope signature tag (PrEST)

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

NUMA1 (Nuclear mitotic apparatus protein 1) is involved in several chromosomal maintenance activities as an essential mitotic component including spindle positioning, proper organization and maintenance of the mitotic spindle structure. During proper positioning and elongation of mitotic spindle, NUMA1, positioned above two spindle poles, directly binds to the conserved proteins (LGN/Gαi1-3) and dynein to the cell cortex. NUMA1-LGN/Gαi1-3 binding finally enhances cortical levels of NuMA/dynein, which is highly essential for robust spindle elongation.

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.
