Ca(2+)/calmodulin-dependent protein kinase IV (CaMKIV) is a multifunctional protein kinase expressed abundantly in the central nervous system. Because changes in intracellular Ca(2+) concentrations affect progression through the mitotic cell cycle, enhanced expression of
CaMKIV has been reported in small cell lung carcinoma and hepatocellular carcinoma (1). Multifunctional Ca2+/calmodulin kinase IV is enriched in neurons and T lymphocytes. The kinase is absent from primary human B lymphocytes but is expressed in Epstein-Barr virus (EBV)- transformed B-lymphoblastoid cell lines, suggesting that expression of the kinase can be upregulated by an EBV gene products. In view of the key role played by LMP1 in B- lymphocyte immortalization by EBV, findings implicate Ca2+/calmodulin kinase IV as a potential mediator of B- lymphocyte growth transformation (2). Ca2+/calmodulin kinase IV can suppress the MT-regulating activity of Op18 by phosphorylation on Ser-16. These results show that Op18
phosphorylation by Ca2+/calmodulin kinase IV may couple alterations of MT dynamics in response to external signals that involve Ca2+ (3).
Suitable for use in Flow Cytometry, Western Blot, Immunoprecipitation and Immunohistochemistry. Other applications not tested.
Flow Cytometry: 1:60
Western Blot: 1:100,000-1:500,000
Optimal dilutions to be determined by the researcher.
Storage and Stability:
May be stored at 4 degrees C for short-term only. For long-term storage, aliquot and store at -20 degrees C. Aliquots are stable for at least 12 months at -20 degrees C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
