Human PAK2 kinase (UniProt: Q13177; NCBI: NM_002577) belongs to a family of p21-activated kinases. These serine/threonine kinases are regulated by the small GTP binding proteins Cdc42 and Rac and have been implicated in a wide range of biological activities. PAK2 is activated by proteolytic cleavage during caspase-mediated apoptosis, and may play a role in regulating the apoptotic events in the dying cell.
PAK2KD is a recombinant wild type human PAK2 kinase domain (amino acids 227–524 of full-length human PAK2) expressed in E. coli and purified to near homogeneity with high specific activity.
Molecular Mass and Phosphorylation:
The calculated mass is 33,510. PAK2KD is fully phosphorylated at T402 and partially phosphorylated at additional sites with measured mass of 33,593 (1P), 33,673 (2P), 33,753 (3P), and 33,834 (4P).
Stability and Storage:
Stable at -70oC for 12 months from date of receipt. Protein should be thawed on ice. Protein can be flash-frozen in liquid nitrogen and stored at -70oC.
