<p>The annotation score provides a heuristic measure of the annotation content of a UniProtKB entry or proteome.

The proteasome is a multicatalytic proteinase complex which is characterized by its ability to cleave peptides with Arg, Phe, Tyr, Leu, and Glu adjacent to the leaving group at neutral or slightly basic pH. The proteasome has an ATP-dependent proteolytic activity. This subunit is involved in antigen processing to generate class I binding peptides. Replacement of PSMB6 by PSMB9 increases the capacity of the immunoproteasome to cleave model peptides after hydrophobic and basic residues.1 Publication

Miscellaneous

Encoded in the MHC class II region.
A model for self-activation in which residue Thr-21 serves as nucleophile and Lys-53 as proton donor/acceptor has been proposed. Subunit processing of mammalian beta-subunits proceeds via a novel ordered two-step mechanism involving autocatalysis.

The disease may be caused by variants affecting distinct genetic loci, including the gene represented in this entry.
Disease descriptionAn autoinflammatory disorder characterized by onset in early infancy and recurrent fever, nodular dermatitis, myositis, panniculitis-induced lipodystrophy, lymphadenopathy, and immune dysregulation. Variable accompanying features may include joint contractures, hepatosplenomegaly, anemia, thrombocytopenia, recurrent infections, autoantibodies, and hypergammaglobulinemia. Some patients may have intracranial calcifications. PRAAS3 inheritance is autosomal recessive or digenic.

The 26S proteasome consists of a 20S proteasome core and two 19S regulatory subunits. The 20S proteasome core is composed of 28 subunits that are arranged in four stacked rings, resulting in a barrel-shaped structure. The two end rings are each formed by seven alpha subunits, and the two central rings are each formed by seven beta subunits. The catalytic chamber with the active sites is on the inside of the barrel.

Component of the immunoproteasome, where it displaces the equivalent housekeeping subunit PSMB6.

<p>The checksum is a form of redundancy check that is calculated from the sequence. It is useful for tracking sequence updates.</p> <p>It should be noted that while, in theory, two different sequences could have the same checksum value, the likelihood that this would happen is extremely low.</p> <p>However UniProtKB may contain entries with identical sequences in case of multiple genes (paralogs).</p> <p>The checksum is computed as the sequence 64-bit Cyclic Redundancy Check value (CRC64) using the generator polynomial: x<sup>64</sup> + x<sup>4</sup> + x<sup>3</sup> + x + 1. The algorithm is described in the ISO 3309 standard. </p> <p class="publication">Press W.H., Flannery B.P., Teukolsky S.A. and Vetterling W.T.<br /> <strong>Cyclic redundancy and other checksums</strong><br /> <a href="http://www.nrbook.com/b/bookcpdf.php">Numerical recipes in C 2nd ed., pp896-902, Cambridge University Press (1993)</a>)</p> Checksum:i3B321F83641941AC
