Preparation and Storage

Background: PSMB10/MECL1

PSMB10 (Proteasome Subunit beta type-10; Also MECL1 and LMP10) is a 25-26 kDa member of the peptidase T1B family of molecules. It is expressed a wide variety of cells, particularly those responsive to proinflammatory cytokines. PSMB10 is expressed both constitutively and via IFN-gamma induction in a cell-specific manner. It contributes to the 700 kDa, 20S proteasome catalytic complex, a dynamic intracellular structure that participates in the ATP-dependent ubiquitin-proteasome-system used for protein degradation. PSMB10 qualifies as a beta -type, i (immuno)-type proteasome, meaning it both plays a catalytic role in the turnover of proteins, and is found in cytokine-responsive cells. The i-type of proteasome is believed to protect cells against the accumulation of oxidant-damaged proteins. This activity is absolutely dependent upon the removal of the precursor's prosequence, an action that exposes a critical internal Thr residue. Human PSMB10 is synthesized as a 29 kDa, 273 amino acid (aa) proprecursor. It contains a 39 aa autocleavable propeptide plus a 234 aa mature region. The mature region shows no identifiable standard structural motifs. Over aa 40-273, human PSMB10 shares 89% aa sequence identity with mouse PSMB10.
