Proteasome 26s
WebbKnockdown of the i-proteasome catalytic subunit PSMB9 by short hairpin RNA (shRNA) decreased the expression of both PSMB9 and PSMB8 without affecting other catalytic subunits of the proteasome. PSMB9 knockdown and the use of i-proteasome-specific inhibitors both decreased 26S proteasome activities and prevented C2C12 differentiation. Webb12 apr. 2024 · The ubiquitin/26S proteasome system is an important protein degradation complex which is responsible for the degradation of ubiquitin-binding proteins. TT1 encodes the 26S proteasome α2 subunit which effectively eliminates the cytotoxic denatured proteins involved in ubiquitination and maintains a dynamic protein balance …
