||Recombinant Human VRK1, Amino acids M1-K396, N-terminally fused to GST-HIS6-Thrombin cleavage site, was produced inSf9cells.MW = 75,142 Da.
||This gene encodes a member of the vaccinia-related kinase (VRK) family of serine/threonine protein kinases. This gene is widely expressed in human tissues and has increased expression in actively dividing cells, such as those in testis, thymus, fetal liver, and carcinomas. Its protein localizes to the nucleus and has been shown to promote the stability and nuclear accumulation of a transcriptionally active p53 molecule and, in vitro, to phosphorylate Thr18 of p53 and reduce p53 ubiquitination.
||Baculovirus infected Sf9 cells.
||One-step affinity purification using GSH-agarose.
||VRK1, was confirmed as VRK1 by mass spectroscopy LC-ESI-MS/MS (Protagen AG, Germany).
