Descripción

General description

LETM1 (Leucine zipper-EF-hand containing transmembrane protein 1) is a mitochondrial inner membrane protein, and is homologous to yeast protein Mdm38p. It was originally recognized as one of the genes deleted in Wolf-Hirschhorn syndrome. It is a transmembrane protein, which has 14-3-3-like domain in its soluble region, two EF hand Ca²⁺-binding motifs and two coiled-coil domains. The C-terminal of this protein is hydrophilic and faces the matrix, whereas the N-terminal is hydrophobic and spans the membrane. It has a molecular weight of 83.4kDa. This gene is located on human chromosome 4p16.3.

Immunogen

LETM1 and EF-hand domain-containing protein 1, mitochondrial Precursor (Leucine zipper-EF-hand-containing transmembrane protein 1)

Application

Anti-LETM1 antibody produced in rabbit, a Prestige Antibody, is developed and validated by the Human Protein Atlas (HPA) project . Each antibody is tested by immunohistochemistry against hundreds of normal and disease tissues. These images can be viewed on the Human Protein Atlas (HPA) site by clicking on the Image Gallery link. The antibodies are also tested using immunofluorescence and western blotting. To view these protocols and other useful information about Prestige Antibodies and the HPA, visit sigma.com/prestige.

Biochem/physiol Actions

LETM1 (Leucine zipper-EF-hand containing transmembrane protein 1) is responsible for maintaining the shape and volume of mitochondria. It plays a part in mitochondrial translation machinery and mitochondrial biogenesis. It regulates the buffering of mitochondria by controlling Ca²⁺/H⁺ antiporter, and also regulates K⁺/H⁺ ion exchange. Inactivation of this gene is associated with Wolf-Hirschhorn syndrome, where it leads to aberration in mitochondrial functionality. It is responsible for growth and motor delay, as well as seizures which characterize Wolf-Hirschhorn syndrome. It is up-regulated in various human cancers, and is involved in the tumorigenesis of head and neck squamous cell carcinoma (HNSCC). It also predicts poor prognosis in HNSCC. Up-regulation of this gene leads to suppressed mitochondrial biogenesis and ATP synthesis, leading to necrotic cell death.

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.
