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. In case of HIV-1 infection, positive modulator of Tat-mediated transactivation. Ref.9
Subunit structure	Interacts with NDC80 and SQSTM1. Interacts with PAAF1. Interacts with HIV-1 Tat. Ref.9 Ref.10 Ref.11 Ref.12
Subcellular location	Cytoplasm. Nucleus.
Sequence similarities	Belongs to the AAA ATPase family.
