Protein FULL name:

UV excision repair protein RAD23 homolog B [Mus musculus].

Rad23b (Mus musculus) is product of expression of Rad23b gene.

FUNCTION: Plays a central role both in proteosomal degradation of misfolded proteins and DNA repair. Central component of a complex required to couple deglycosylation and proteasome-mediated degradation of misfolded proteins in the endoplasmic reticulun that are retrotranslocated in the cytosol. Involved in DNA excision repair by stabilizing XPC protein. May play a part in DNA damage recognition and/or in altering chromatin structure to allow access by damage-processing enzymes.

SUBUNIT: Interacts with the 26S proteasome (By similarity). Component of a complex required to couple retrotranslocation, ubiquitination and deglycosylation composed of NGLY1, SAKS1, AMFR, VCP and RAD23B. Interacts directly with NGLY1. Heterodimer of a 125 kDa subunit (p125) and of a 58 kDa subunit (p58). Interacts with MJD and XPC.


SIMILARITY: Belongs to the RAD23 family.

SIMILARITY: Contains 1 STI1 domain.

SIMILARITY: Contains 2 UBA domains.

SIMILARITY: Contains 1 ubiquitin-like domain.

NCBI GenPept GI number(s): 171906578
Species: Mus musculus
