Protein attributes

Sequence length	615 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is not processed.
Protein existence	Evidence at protein level.

General annotation (Comments)

Function	Specific down-regulator of the NEDD8 conjugation system. Recruits NEDD8 and its conjugates to the proteasome for degradation. Isoform 1 promotes the degradation of NEDD8 more efficiently than isoform 2.
Subunit structure	Directly interacts with NEDD8 and PSMD4/S5a, a member of the regulatory subunit of the 26S proteasome. Isoform 1 binds to NEDD8 more efficiently than isoform 2. Interacts with AIPL1. Ref.2 Ref.7 Ref.8
Subcellular location	Nucleus. Note: Predominantly nuclear. Ref.2
Tissue specificity	Widely expressed with lowest expression in the pancreas for isoform 1 and in leukocytes, liver, prostate and skeletal muscle for isoform 2.
Induction	By beta and gamma interferons. Ref.2
Sequence similarities	Contains 3 UBA domains.
Sequence caution	The sequence AAD42865.1 differs from that shown. Reason: Frameshift at positions 365 and 393.
