NCBI Summary for MAPKK5 (MEK5)
The protein encoded by this gene is a dual specificity protein kinase that belongs to the MAP kinase kinase family. This kinase specifically interacts with and activates MAPK7/ERK5. This kinase itself can be phosphorylated and activated by MAP3K3/MEKK3, as well as by atypical protein kinase C isoforms (aPKCs). The signal cascade mediated by this kinase is involved in growth factor stimulated cell proliferation and muscle cell differentiation. Three alternatively spliced transcript variants of this gene encoding distinct isoforms have been described. [provided by RefSeq]
UniProt Comments for MAPKK5 (MEK5)
Function: Acts as a scaffold for the formation of a ternary MAP3K2/MAP3K3-MAP3K5-MAPK7 signaling complex. Activation of this pathway appear to play a critical role in protecting cells from stress-induced apopotosis, neuronal survival and cardiac development and angiogenesis. Ref.1 Ref.2
Catalytic activity: ATP + a protein = ADP + a phosphoprotein.
Cofactor: Magnesium.
Subunit structure: Interacts with PARD6A, MAP3K3 and MAPK7. Forms a complex with SQSTM1 and PRKCZ or PRKCI
By similarity. Interacts with Yersinia yopJ. Ref.1 Ref.7
Tissue specificity: Expressed in many adult tissues. Abundant in heart and skeletal muscle.
Domain: Binds MAP3K2/MAP3K3 and MAPK7 via non-overlapping residues of the OPR domain. This domain also mediates interactions with SQSTM1 and PARD6A
Post-translational modification: Activated by phosphorylation on Ser/Thr by MAP kinase kinase kinases
By similarity.Yersinia yopJ may acetylate Ser/Thr residues, preventing phosphorylation and activation, thus blocking the MAPK signaling pathway.
Sequence similarities: Belongs to the protein kinase superfamily. STE Ser/Thr protein kinase family. MAP kinase kinase subfamily.Contains 1 OPR domain.Contains 1 protein kinase domain.
