Abstract
Extracellular signal-regulated kinases (ERKs) are a subgroup of mitogen-activated protein kinases (MAPK) that function as important intermediates in signal transduction pathways initiated by several types of cell surface receptors. We cloned a transcript of ERK1 from a cDNA library of flounder leukocytes stimulated with bacterial lipopolysaccharide and hemagglutinin lectin. Flounder ERK1 consists of 1502 nucleotides and encodes a polypeptide of 393 amino acids. Flounder ERK1 showed 90 and 89% amino acid sequence identity to ERK1 of carp and zebrafish, respectively, and over 85% to that of mammals. Multiple bands were detected by Southern blot analysis of flounder genomic DNA after digestion with various restriction enzymes, implying the presence of additional MAPK genes in flounder. Real-time PCR revealed the ubiquitous expression of flounder MAPK in all tissues with high levels of transcription in brain, gill, and fin, but not in muscle or skin. Flounder MAPK was successfully expressed in mammalian COS1 cells and phosphorylated myelin basic protein (MBP) substrate when the cells were stimulated with PMA or EGF, indicating that flounder MAPK is functional in animal cells.
