Mitogen-activated protein kinase in Pfiesteria piscicida and its growth rate-related expression

Results document the isolation of cDNA fragment of mitogen-activated protein kinase from the dinoflagellate Pfiesteria piscicida and its encoded product containing 428 amino acid residues matching 30 to 40% of residues of the mitogen-activated protein kinase from other organisms. Growth analysis indicates that the cDNA gene expression is correlated with growth rate and perhaps regulates cell proliferation.
