Protein attributes

Sequence length	406 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is further processed into a mature form.
Protein existence	Evidence at protein level

General annotation (Comments)

Function	The 26S protease is involved in the ATP-dependent degradation of ubiquitinated proteins. The regulatory (or ATPase) complex confers ATP dependency and substrate specificity to the 26S complex.
Subunit structure	Interacts, in vitro, with the thyroid hormone receptor (in a thyroid hormone T3-dependent manner) and with retinoid X receptor (RXR) By similarity. Interacts with NDC80. Interacts with PAAF1. Ref.7 Ref.8 Ref.9
Subcellular location	Cytoplasm Potential. Nucleus Potential.
Sequence similarities	Belongs to the AAA ATPase family.
