General description

KARS, also known as Lysyl-tRNA synthetase (LysRS), is the enzyme that connects the lysine to its specific tRNA for use in protein translation. KARS is also a powerful inflammatory agent when released into extracellular matrix as one might expect. KARS is largely cytoplasmically localized or localized to internal membranes but isoforms are found in the mitochondria and nucleus as well. KARS became the focus of much attention with HIV-1 as KARS interacted with HIV-1's GAG protein and facilitated the selective packaging of tRNA3(lys) nucleic acid which acted as the primer for viral reverse transcription and initiation of viral gene expression. There is also at least one genetic disease linked to KARS. It is the cause of Charcot-Marie-Tooth neuropathy a progressive peripheral nervous system disease characterized by progressive weakness and atrophy of the muscles and demyelination and deterioration the peripheral nerves and axons. EMD-Millipore's Anti-KARS mouse monoclonal antibody has been tested in western blot on recombinant protein and in paraffin embedded immunohistochemistry on human cervical carcinoma tissue sections.
