Functional Description (View all) |
Component of the ribosome quality control complex (RQC), a ribosome-associated complex that mediates ubiquitination and extraction of incompletely synthesized nascent chains for proteasomal degradation. Mtr1/rqc2 is responsible for selective recognition of stalled 60S subunits by recognizing an exposed, nascent chain-conjugated tRNA moiety. Mtr1/rqc2 is important for the stable association of rkr1/ltn1 to the complex. Mtr1/rqc2 recruits alanine- and threonine-charged tRNA to the A site and directs the elongation of stalled nascent chains independently of mRNA or 40S subunits, leading to non-templated C-terminal Ala and Thr extensions (CAT tails). CAT tails induce a heat shock response. | ||||||||
