data demonstrate that sequestration and impairment of nuclear HR23 and nucleocytoplasmic transport proteins is an outcome of, and a contributor to, poly(GA) pathology.
Title: C9ORF72 poly(GA) aggregates sequester and impair HR23 and nucleocytoplasmic transport proteins.
the mammalian RAD23 proteins play a direct role in damage recognition by enhancing the binding of XPC to DNA damage in living cells in addition to stabilizing XPC. RAD23 proteins rapidly dissociated from XPC upon binding to damaged DNA.
Title: Recognition of DNA damage by XPC coincides with disruption of the XPC-RAD23 complex.
This illustrates that impairment of the ubiquitin-proteasome system (UPS) by expanded glutamine repeats, including the sequestration of HR23B, is not affecting NER.
Title: The DNA repair-ubiquitin-associated HR23 proteins are constituents of neuronal inclusions in specific neurodegenerative disorders without hampering DNA repair.
The crystal structure of the mouse peptide N-glycanase catalytic core in complex with the xeroderma pigmentosum group C binding domain from HR23B is described; the results suggest a co-evolution of ER-associated degradation and DNA repair pathways.
Title: Structure of the mouse peptide N-glycanase-HR23 complex suggests co-evolution of the endoplasmic reticulum-associated degradation and DNA repair pathways.
analysis of mHR23A/B double-mutant cells showed that HR23 proteins function in nucleotide excision repair by governing xeroderma pigmentosum group C protein stability via partial protection against proteasomal degradation
Title: A novel regulation mechanism of DNA repair by damage-induced and RAD23-dependent stabilization of xeroderma pigmentosum group C protein.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
