AIMP2 antibody can be used for detection of AIMP2 by Western blot at 1 - 2 μg/ml.
Antibody validated: Western Blot in human samples; Immunohistochemistry in rat samples and Immunofluorescence in rat samples. All other applications and species not yet tested.
AIMP2 was initially identified as a part of an aminoacyl-tRNA synthesase complex (1). It was later discovered to be a cofactor and substrate of Parkin, a Ring-type E3 ubiquitin ligase that is important for the survival of dopamine neurons in Parkinson?s disease; accumulation of AIMP2 in these cells lead to catecholaminergic cell death (2). AIMP2 can also bind to TRAF2, a key player in the TNF-alpha signaling pathway, causing the ubiquitination of TRAF2 by cIAP1, leading to TNF-alpha-dependent apoptosis (3). Finally, AIMP2 has been suggested to function as a tumor suppressor (4).
