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

The gene IQGAP1 (IQ motif containing GTPase activating protein 1) encodes a key effector of Rac1 and Cdc42, Rho-family of small GTPases that regulate E-cadherin–mediated cell-cell adhesion. It functions in the modulation of actin cytoskeleton along with Rac1 and Cdc42. The encoded protein modulates cell–cell adhesion through E-cadherin and β-catenin. It participates in the regulation of mitogen activated protein kinase pathway that is involved in cell proliferation and differentiation. IQGAP1 is a scaffold protein that bridges the proteins involved in signaling cascades and participates in several cellular processes. It binds to and stabilizes microtubules via CLIP-170, a microtubule-binding protein, near the cell cortex. This results in the formation and maintenance of polarized cell morphology and directional cell migration.

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

The gene IQGAP1 (IQ motif containing GTPase activating protein 1) encodes a calmodulin-binding protein that belongs to the IQGAP family and is ubiquitously expressed. The encoded protein contains four IQ domains and a region with sequence similarity to the Ras GTPase-activating proteins. The gene is mapped to human chromosome 15q26.1.
