A 220-kDa Activator Complex of the 26 S Proteasome in Insects and Humans

TLDR
The S10b (SUG2) ATPase cDNA has been cloned by reverse transcription-polymerase chain reaction/rapid amplification of cDNA ends from mRNA of intersegmental muscles of the tobacco horn moth and may have a fundamental role in proteasome regulation.

TLDR
Both qualitative and quantitative differences in compositions between wild-type (+/+) and heterozygotes (+/DTS) indicated that incorporation of mutant subunits alters post-translational modifications of the complex, which suggests that the developmental defect involves other proteasome properties, such as intracellular localization and/or interactions with endogenous regulators.

Ubiquitin and actin expression in claw muscles of land crab, Gecarcinus lateralis, and American lobster, Homarus americanus: differential expression of ubiquitin in two slow muscle fiber types during molt-induced atrophy.

TLDR
The results suggest that Ub/proteasome-dependent proteolysis contributes to enhanced turnover of myofibrillar proteins during claw closer muscle atrophy.

Role of proteasomes in cellular regulation.

The 26S proteasome assembly is regulated by a maturation-inducing hormone in starfish oocytes.

TLDR
The proteasome undergoes changes in molecular assembly and activities during hormone-induced oocyte maturation, and Immunoblot analysis revealed that the change in the 26S proteasomal activity is due to thechange in the amount of the 20S proteAsome subcomplex.
