Functional Studies - H89 dihydrochloride, Kinase inhibitor (AB120341)
Normal human melanocytes (NHMs) were treated with ab120341 at the indicated concentrations to test if the inhibition of MSK1 activation results in the down-regulated MITF and EDNRB expression in UVB-exposed NHMs. ab120341 was added immediately after UVB irradiation and cells were cultured for 6h (for MITF, A) or 24 h (for EDNRB, B). Total mRNAs were purified and Real-time RT-PCR was carried out with MITF or EDNRB primer and β-actin primer as the internal control. Error bars represent S.D. from triplicate experiments. *P<0.05 and **P<0.01 against NHMs UVB-irradiated in the absence of H89, respectively.

Biological function summary
AKT3 and AKT2 influence processes like glucose uptake cell proliferation and suppression of apoptosis. These proteins do not form a stable complex but interact with other proteins as part of their activation and signaling processes. The cAMP Protein Kinase Catalytic subunit often called PKA C or PKAc is involved in similar pathways regulating numerous cellular processes through phosphorylation events. ROCK2 or Rho-associated coiled-coil containing protein kinase 2 acts in cytoskeletal dynamics influencing cell shape and movement.
Pathways
AKT3 participates in the PI3K/AKT signaling pathway important for transmitting extracellular signals into the cell influencing growth and survival. In this pathway AKT3 and AKT2 interact with proteins like mTOR and GSK-3 which help regulate cell cycle progression and metabolism. ROCK2 is mainly involved in the RhoA/ROCK pathway modulating actin cytoskeleton organization and affecting processes such as contraction cell migration and proliferation.
