MAPKK3 | definition of MAPKK3 by Medical dictionary
MAP2K3 (redirected from MAPKK3)
MAP2K3 A gene on chromosome 17q11.2 that encodes a MAPK kinase belonging to a protein kinase signal transduction cascade. MAP2K3 is a dual-specificity kinase, which is activated by cytokines and environmental stress; it catalyses phosphorylation of threonine and tyrosine residues in MAPK14/MAP kinase p38.
Defects in MAP2K3 have been described in colorectal cancer.

Several years later, another group of scientists has interestingly revealed that, without drug treatment, the [gamma]-globin mRNA level is increased sufficiently solely by overexpressing MAPKK3
and MAPKK 6 which are the direct upstream activators of p38 in K562 cells .
A study conducted by Yang and coworkers (2010) confirmed this hypothesis by demonstrating that PEITC inhibits ERK1/2, MAPK kinase 7 (MAPKK7), and MAPK kinase kinase 3 (MAPKK3
Higher doses of arsenic increase levels of jun kinases (JNKs), possibly via mitogen-activated protein kinase kinases, such as MAPKK3
, and also activate MAP kinases such as extracellular signal regulated kinase (ERK3) (Cavigelli et al.
