ID:PSMD5_HUMAN DESCRIPTION: RecName: Full=26S proteasome non-ATPase regulatory subunit 5; AltName: Full=26S protease subunit S5 basic; AltName: Full=26S proteasome subunit S5B; FUNCTION: Acts as a chaperone during the assembly of the 26S proteasome, specifically of the base subcomplex of the PA700/19S regulatory complex (RC). In the initial step of the base subcomplex assembly is part of an intermediate PSMD5:PSMC2:PSMC1:PSMD2 module which probably assembles with a PSMD10:PSMC4:PSMC5:PAAF1 module followed by dissociation of PSMD5. SUBUNIT: Interacts with PSMC1, PSMC2, PSMD1 and PSMD6. Part of transient complex containing PSMD5, PSMC2, PSMC1 and PSMD2 formed during the assembly of the 26S proteasome. INTERACTION: P35998:PSMC2; NbExp=4; IntAct=EBI-752143, EBI-359710; DOMAIN: Rich in dileucine repeats, which have been implicated in trafficking of a variety of transmembrane proteins. SIMILARITY: Belongs to the proteasome subunit S5B/HSM3 family. CAUTION: Was initially identified as a genuine component of the 26S proteasome.
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.
