Gene Information

human ... MYO7B(4648)

General description

Myosin-7b (MYO7B) is a novel unconventional myosin, encoded by the gene mapped to human chromosome 2q21.1. The encoded protein is characterized by a conserved myosin head domain, five IQ domains, two MyTH4-four-point-one, ezrin, radixin, moesin (FERM) domains and an intermediate SH3 domain. Myo7b is abundantly expressed at the tips of microvilli in both kidney and intestinal brush borders.

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.
Anti-MYO7B antibody produced in rabbit has been used in immunostaining technique.

Biochem/physiol Actions

Myosin-7b (MYO7B) might facilitate the localization of adhesion molecules to microvillar tips. It is the only actin-binding component of the intermicrovillar adhesion complex (IMAC). Defect in the Myo7b expression, impairs tip targeting of intermicrovillar adhesion factors and thus, disrupts brush border assembly.

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.

Transporting epithelial cells interact with the luminal environment using a tightly packed array of microvilli known as the brush border. During intestinal epithelial differentiation, microvillar packing and organization are driven by cadherin-dependent adhesion complexes that localize to the distal tips
