Abstract

Mitogen-activated protein (MAP) kinases [also known as Erks] have been established to function as important mediators of signal transduction by growth factor receptors. Several components of the MAP kinase signal transduction pathway have been demonstrated to be oncogenically activated in malignant tumors. These include growth factor receptors, the GTP-binding protein Ras, and the protein kinase Raf. The genes that encode MAP kinases therefore represent potential targets of carcinogenic insults. Here, we report the genomic loci of three MAP kinase genes are widely distributed within the human genome: p41mapk (Erk2) at 22q11.2; p44mapk (Erk1) at 16p11.2; and p63mapk (Erk3-related) at 18q12-21.
