Human Gene MAP2K5 (ENST00000354498.9) Description and Page Index
Description: Homo sapiens mitogen-activated protein kinase kinase 5 (MAP2K5), transcript variant 3, mRNA. (from RefSeq NM_001206804) RefSeq Summary (NM_001206804): 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, May 2011]. Gencode Transcript: ENST00000354498.9 Gencode Gene: ENSG00000137764.20 Transcript (Including UTRs) Position: hg38 chr15:67,548,998-67,807,111 Size: 258,114 Total Exon Count: 22 Strand: + Coding Region Position: hg38 chr15:67,549,181-67,806,750 Size: 257,570 Coding Exon Count: 22
ID:MP2K5_HUMAN DESCRIPTION: RecName: Full=Dual specificity mitogen-activated protein kinase kinase 5; Short=MAP kinase kinase 5; Short=MAPKK 5; EC=18.104.22.168; AltName: Full=MAPK/ERK kinase 5; Short=MEK 5; FUNCTION: Acts as a scaffold for the formation of a ternary MAP3K2/MAP3K3-MAP3K5-MAPK7 signaling complex. Activation of this pathway appears to play a critical role in protecting cells from stress-induced apoptosis, neuronal survival and cardiac development and angiogenesis. CATALYTIC ACTIVITY: ATP + a protein = ADP + a phosphoprotein. COFACTOR: Magnesium. SUBUNIT: Interacts with PARD6A, MAP3K3 and MAPK7. Forms a complex with SQSTM1 and PRKCZ or PRKCI (By similarity). Interacts with Yersinia yopJ. INTERACTION: P62993:GRB2; NbExp=2; IntAct=EBI-307294, EBI-401755; Q13164:MAPK7; NbExp=2; IntAct=EBI-307294, EBI-1213983; 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 (By similarity). PTM: Activated by phosphorylation on Ser/Thr by MAP kinase kinase kinases (By similarity). PTM: Yersinia yopJ may acetylate Ser/Thr residues, preventing phosphorylation and activation, thus blocking the MAPK signaling pathway. SIMILARITY: Belongs to the protein kinase superfamily. STE Ser/Thr protein kinase family. MAP kinase kinase subfamily. SIMILARITY: Contains 1 OPR domain. SIMILARITY: Contains 1 protein kinase domain.
The RNAfold program from the Vienna RNA Package is used to perform the secondary structure predictions and folding calculations. The estimated folding energy is in kcal/mol. The more negative the energy, the more secondary structure the RNA is likely to have.
ModBase Predicted Comparative 3D Structure on Q13163
The pictures above may be empty if there is no ModBase structure for the protein. The ModBase structure frequently covers just a fragment of the protein. You may be asked to log onto ModBase the first time you click on the pictures. It is simplest after logging in to just click on the picture again to get to the specific info on that model.
Orthologous Genes in Other Species
Orthologies between human, mouse, and rat are computed by taking the best BLASTP hit, and filtering out non-syntenic hits. For more distant species reciprocal-best BLASTP hits are used. Note that the absence of an ortholog in the table below may reflect incomplete annotations in the other species rather than a true absence of the orthologous gene.
