ID:PJA2_HUMAN DESCRIPTION: RecName: Full=E3 ubiquitin-protein ligase Praja-2; Short=Praja2; EC=6.3.2.-; AltName: Full=RING finger protein 131; FUNCTION: Has E2-dependent E3 ubiquitin-protein ligase activity. Responsible for ubiquitination of cAMP-dependent protein kinase type I and type II-alpha/beta regulatory subunits and for targeting them for proteasomal degradation. Essential for PKA- mediated long-term memory processes. PATHWAY: Protein modification; protein ubiquitination. SUBUNIT: Binds ubiquitin-conjugating enzymes (E2s). In vitro, interacts with the ubiquitin-conjugating enzyme, UBE2D2. The phosphorylated form interacts with PRKAR1A, PRKAR2A and PRKAR2B. Binds the catalytic subunits of cAMP-dependent protein kinase. SUBCELLULAR LOCATION: Cytoplasm. Cell membrane. Endoplasmic reticulum membrane; Peripheral membrane protein. Golgi apparatus membrane; Peripheral membrane protein. Cell junction, synapse (By similarity). Cell junction, synapse, postsynaptic cell membrane, postsynaptic density (By similarity). Note=Localizes at the cytoplasmic side of endoplasmic reticulum and Golgi apparatus. Expressed in the postsynaptic density region of synapses (By similarity). Co-localizes with PRKAR2A and PRKAR2B in the cytoplasm and the cell membrane. SIMILARITY: Contains 1 RING-type zinc finger. SEQUENCE CAUTION: Sequence=BAA23710.2; Type=Erroneous initiation; Note=Translation N-terminally shortened;
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.
