Protein attributes

Sequence length	908 AA.
Sequence status	Complete.
Protein existence	Evidence at protein level

General annotation (Comments)

Function	Acts as a regulatory subunit of the 26 proteasome which is involved in the ATP-dependent degradation of ubiquitinated proteins. Binds to the intracellular domain of tumor necrosis factor type 1 receptor. The binding domain of TRAP1 and TRAP2 resides outside the death domain of TNFR1.
Tissue specificity	Found in skeletal muscle, liver, heart, brain, kidney, pancreas, lung and placenta.
Sequence similarities	Belongs to the proteasome subunit S2 family. Contains 7 PC repeats.
Sequence caution	The sequence AAA87705.1 differs from that shown. Reason: Erroneous initiation.
