RKR1/YMR247C Summary Help

Standard Name RKR1 1
Systematic Name YMR247C
Alias LTN1 2
Feature Type ORF, Verified
Description RING domain E3 ubiquitin ligase; involved in ubiquitin-mediated degradation of non-stop proteins; component of ribosome-bound RQC (ribosome quality control) complex required for degradation of polypeptides arising from stalled translation; degrades products of mRNAs lacking a termination codon regardless of a poly(A) tail; functional connections to chromatin modification; homolog of mouse Listerin, mutations in which reported to cause neurodegeneration (1, 2, 3, 4, 5)
Name Description RING domain mutant Killed by rtf1 deletion 1
