Description: Homo sapiens protein phosphatase 2, regulatory subunit B', epsilon isoform (PPP2R5E), mRNA. RefSeq Summary (NM_006246): The protein encoded by this gene belongs to the phosphatase 2A regulatory subunit B family. Protein phosphatase 2A is one of the four major Ser/Thr phosphatases, and it is implicated in the negative control of cell growth and division. It consists of a common heteromeric core enzyme, which is composed of a catalytic subunit and a constant regulatory subunit, that associates with a variety of regulatory subunits. The B regulatory subunit might modulate substrate selectivity and catalytic activity. This gene encodes an epsilon isoform of the regulatory subunit B56 subfamily. Multiple transcript variants encoding several different isoforms have been found for this gene. [provided by RefSeq, Aug 2013].

ID:2A5E_HUMAN DESCRIPTION: RecName: Full=Serine/threonine-protein phosphatase 2A 56 kDa regulatory subunit epsilon isoform; AltName: Full=PP2A B subunit isoform B'-epsilon; AltName: Full=PP2A B subunit isoform B56-epsilon; AltName: Full=PP2A B subunit isoform PR61-epsilon; AltName: Full=PP2A B subunit isoform R5-epsilon; FUNCTION: The B regulatory subunit might modulate substrate selectivity and catalytic activity, and also might direct the localization of the catalytic enzyme to a particular subcellular compartment. SUBUNIT: Found in a complex with at least ARL2, PPP2CB; PPP2R1A, PPP2R2A, PPP2R5E and TBCD (By similarity). PP2A consists of a common heterodimeric core enzyme, composed of a 36 kDa catalytic subunit (subunit C) and a 65 kDa constant regulatory subunit (PR65 or subunit A), that associates with a variety of regulatory subunits. Proteins that associate with the core dimer include three families of regulatory subunits B (the R2/B/PR55/B55, R3/B''/PR72/PR130/PR59 and R5/B'/B56 families), the 48 kDa variable regulatory subunit, viral proteins, and cell signaling molecules. Interacts with SGOL1. INTERACTION: O96017:CHEK2; NbExp=3; IntAct=EBI-968374, EBI-1180783; P30154:PPP2R1B; NbExp=2; IntAct=EBI-968374, EBI-357094; SUBCELLULAR LOCATION: Cytoplasm. PTM: Phosphorylated on serine residues. SIMILARITY: Belongs to the phosphatase 2A regulatory subunit B56 family.

In the community-based Framingham Heart Study none of the ECG and HRV results individually attained genomewide significance. However, the presence of bona fide QT-associated SNPs among the top 117 results for QT duration supports the importance of efforts to validate top results from the reported scans. Finding genetic variants associated with ECG and HRV quantitative traits may identify novel genes and pathways implicated in arrhythmogenesis and allow for improved recognition of individuals at high risk for arrhythmias in the general population.
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.
