Description_x000D_ Biochem/physiol Actions_x000D_ PAK7 (p21 protein (Cdc42/Rac)-activated kinase 7) belongs to the group-2 PAKs and can activate JNK (Jun N-terminus kinase). It contain an amino-terminal CDC42 (cell division cycle 42)/RAC (AKT1, v-akt murine thymoma viral oncogene homolog 1) interactive domain and a carboxyl terminal kinase domain. It plays an important role in outgrowth of neuron cells and synaptic vesicle trafficking. In mice, absence of PAK7 and PAK6 causes learning and locomotion defects. It is mainly expressed in brain. However, it is also considered as an oncogene because of its expression in colorectal, esophageal and gastric cancers._x000D_ Physical form_x000D_ Supplied in 50 mM Tris-HCl, pH 7.5, with 150 mM NaCl, 0.2 5mM DTT, 0.1 mM EGTA, 0.1 mM EDTA, 0.1 mM PMSF, and 25% glycerol._x000D_ Legal Information_x000D_ PRECISIO is a registered trademark of Sigma-Aldrich Co.
