Localisation Expression of tRNA isopentenyltransferase

Generally, this enzyme is expressed in all tissue types since it is important that functional protein are synthesized in each of these tissues. Specifically, it is highly expressed in adipose tissues as well as oocytes. Relatively high amounts of this enzyme is expressed in prostate, adrenal gland, B-cells and trachea. The reason why tRNA-IPT are at higher concentrations in these tissues may reflect higher levels of protein synthesis.
