Our Abpromise guarantee covers the use of ab95310 in the following tested applications.

The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

  • Biological activity
    86 nmoles/min/µg Analysis of enzymatic activity: 1. Different concentrations of PAK2 were incubated in a buffer containing 50 mM HEPES (pH7.5), 10 mM MgCl2, 1 mM EGTA, 200 µM ATP, 0.01% Brij-35, and 2 µM substrate (SER/THR 20) at room temperature for 1 hour. 2. Developer solution was added to reaction and reaction was stopped after 1h of incubation at RT. 3. Fluorescence was detected using ?exc=460±40 nm and ?em=528±20 nm filters.

  • Function
    The activated kinase acts on a variety of targets. Phosphorylates ribosomal protein S6, histone H4 and myelin basic protein. Full length PAK 2 stimulates cell survival and cell growth. The process is, at least in part, mediated by phosphorylation and inhibition of pro-apoptotic BAD. Caspase-activated PAK-2p34 is involved in cell death response, probably involving the JNK signaling pathway. Cleaved PAK-2p34 seems to have a higher activity than the CDC42-activated form.
  • Tissue specificity
    Ubiquitously expressed. Higher levels seen in skeletal muscle, ovary, thymus and spleen.
  • Sequence similarities
    Belongs to the protein kinase superfamily. STE Ser/Thr protein kinase family. STE20 subfamily.
    Contains 1 CRIB domain.
    Contains 1 protein kinase domain.
  • Post-translational
    Full length PAK 2 is autophosphorylated when activated by CDC42/p21. Following cleavage, both peptides, PAK-2p27 and PAK-2p34, become highly autophosphorylated, with PAK-2p27 being phosphorylated on serine and PAK-2p34 on threonine residues, respectively. Autophosphorylation of PAK-2p27 can occur in the absence of any effectors and is dependent on phosphorylation of Thr-402, because PAK-2p27 is acting as an exogenous substrate.
    During apoptosis proteolytically cleaved by caspase-3 or caspase-3-like proteases to yield active PAK-2p34.
    Ubiquitinated, leading to its proteasomal degradation.
    PAK-2p34 is myristoylated.
  • Cellular localization
    Cytoplasm and Nucleus. Cytoplasm > perinuclear region. Membrane. Interaction with ARHGAP10 probably changes PAK-2p34 location to cytoplasmic perinuclear region. Myristoylation changes PAK-2p34 location to the membrane.
