Description: Homo sapiens cell division cycle 25C (CDC25C), transcript variant 1, mRNA. RefSeq Summary (NM_001790): This gene encodes a conserved protein that plays a key role in the regulation of cell division. The encoded protein directs dephosphorylation of cyclin B-bound CDC2 and triggers entry into mitosis. It also suppresses p53-induced growth arrest. Multiple alternatively spliced transcript variants of this gene have been described. [provided by RefSeq, Dec 2015]. Transcript (Including UTRs) Position: hg19 chr5:137,620,959-137,667,516 Size: 46,558 Total Exon Count: 14 Strand: - Coding Region Position: hg19 chr5:137,621,381-137,666,869 Size: 45,489 Coding Exon Count: 13
ID:MPIP3_HUMAN DESCRIPTION: RecName: Full=M-phase inducer phosphatase 3; EC=3.1.3.48; AltName: Full=Dual specificity phosphatase Cdc25C; FUNCTION: Functions as a dosage-dependent inducer in mitotic control. Tyrosine protein phosphatase required for progression of the cell cycle. When phosphorylated, highly effective in activating G2 cells into prophase. Directly dephosphorylates CDK1 and activates its kinase activity. CATALYTIC ACTIVITY: Protein tyrosine phosphate + H(2)O = protein tyrosine + phosphate. SUBUNIT: Interacts with HIV-1 Vpr, thereby inactivating CDC25C phosphatase activity. Interacts with MAPK14 and 14-3-3 proteins. When phosphorylated on Ser-129 and/or Thr-130, interacts with PLK1. INTERACTION: P06493:CDK1; NbExp=2; IntAct=EBI-974439, EBI-444308; O14757:CHEK1; NbExp=2; IntAct=EBI-974439, EBI-974488; Q9Y250:LZTS1; NbExp=2; IntAct=EBI-974439, EBI-1216080; SUBCELLULAR LOCATION: Nucleus. DEVELOPMENTAL STAGE: Expressed predominantly in G2 phase. PTM: Phosphorylated by CHEK1 and MAPK14 at Ser-216. This phosphorylation creates a binding site for 14-3-3 protein and inhibits the phosphatase. Phosphorylated by PLK4. Phosphorylated by PLK1, leading to activate the phosphatase activity. Phosphorylation by PLK3 at Ser-191 promotes nuclear translocation. Ser-198 is a minor phosphorylation site. Was initially reported to be phosphorylated by PLK3 at Ser-216 (PubMed:10557092). However, such phosphorylation by PLK3 was not confirmed by other groups. Phosphorylation at Thr-48, Thr-67, Ser-122, Thr-130, Ser-168 and Ser-214 occurs at G2 and G2-M transition and is probably catalyzed by CDK1. Ser-168 phosphorylation levels are lower than those at the other 5 CDK1 sites. Phosphorylation by CDK1 leads to increased activity. SIMILARITY: Belongs to the MPI phosphatase family. SIMILARITY: Contains 1 rhodanese domain. WEB RESOURCE: Name=NIEHS-SNPs; URL="http://egp.gs.washington.edu/data/cdc25c/";
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.

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.
