UniProtKB accession:  Q9CR50

Grouped By:  Matching UniProtKB accession

UniProtKB description:  E3 ubiquitin-protein ligase that mediates ubiquitination of target proteins, including p53/TP53, TP73, HDAC1 and CDKN1B (By similarity). Mediates ubiquitination and degradation of p53/TP53; preferentially acts on tetrameric p53/TP53 (By similarity). Catalyzes monoubiquitinates the translesion DNA polymerase POLH (PubMed:12654245). Involved in the ribosome-associated quality control (RQC) pathway, which mediates the extraction of incompletely synthesized nascent chains from stalled ribosomes: RCHY1 acts downstream of NEMF and recognizes CAT tails associated with stalled nascent chains, leading to their ubiquitination and degradation (By similarity).
