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 aminoacyl-tRNA synthetases are responsible for catalyzing the attachment of the correct amino acid to its related tRNA. Phenylalanyl-tRNA synthetase (FARS2) could also catalyze binding of oxidized phenylalanine, meta-tyrosine, to the tRNAPhe. This causes transfer of the misacylated tRNA to the ribosome and addition of ROS-damaged amino acid into eukaryotic proteins. Humans with heterozygous mutations in FARS2 (I329T, D391V, Y144C) suffer from fatal epileptic mitochondrial encephalopathy. FARS2 mutations impair the aminoacylation function and stability of the protein, leading to decrease in tRNA charging capacity. Additionally, missense mutation in FARS2 (D325Y) causes mitochondrial disease phenotype associated with respiratory chain dysfunction (respiratory chain complex IV deficiency in muscle) and early-onset epilepsy.

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 Phenylalanyl-tRNA synthetase (FARS2) has been mapped to human chromosome 6p25.1. Three isoforms of phenylalanyl-tRNA synthase exist: the bacterial (αβ)₂ heterodimer, the archaeal/eukaryotic cytosolic (αβ)₂ heterodimer and the mitochondrial monomer. The human mitochondrial phenylalanyl-tRNA synthetase (FARS2) consists of a single polypeptide chain and is the smallest known nuclear-encoded synthetase. The protein has four major domains: an N-terminal region, a catalytic domain, a linker region and a C-terminal domain.
