ID:PSDE_HUMAN DESCRIPTION: RecName: Full=26S proteasome non-ATPase regulatory subunit 14; EC=3.4.19.-; AltName: Full=26S proteasome regulatory subunit RPN11; AltName: Full=26S proteasome-associated PAD1 homolog 1; FUNCTION: Metalloprotease component of the 26S proteasome that specifically cleaves 'Lys-63'-linked polyubiquitin chains. The 26S proteasome is involved in the ATP-dependent degradation of ubiquitinated proteins. Plays a role in response to double-strand breaks (DSBs): acts as a regulator of non-homologous end joining (NHEJ) by cleaving 'Lys-63'-linked polyubiquitin, thereby promoting retention of JMJD2A/KDM4A on chromatin and restricting TP53BP1 accumulation. Also involved in homologous recombination repair by promoting RAD51 loading. SUBUNIT: Component of the lid subcomplex of the 19S proteasome regulatory particle complex (also named PA700 complex). The 26S proteasome consists of a 20S proteasome core and two 19S regulatory subunits. Interacts with TXNL1. TISSUE SPECIFICITY: Widely expressed. Highest levels in heart and skeletal muscle. SIMILARITY: Belongs to the peptidase M67A family. PSMD14 subfamily. SIMILARITY: Contains 1 MPN (JAB/Mov34) 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.

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.
