MCD1

PDS3, RHC21, SCC1, L000002676, YDL003W
Essential alpha-kleisin subunit of the cohesin complex; required for sister chromatid cohesion in mitosis and meiosis; apoptosis induces cleavage and translocation of a C-terminal fragment to mitochondria; expression peaks in S phase
Saccharomyces cerevisiae (S288c)

UBR1

PTR1, E3 ubiquitin-protein ligase UBR1, L000002420, YGR184C
E3 ubiquitin ligase (N-recognin); heterodimerizes with Rad6p to ubiquitinate substrates in the N-end rule pathway; role in endoplasmic reticulum-associated protein degradation (ERAD) in the absence of canonical ER membrane ligases or after stress; major role in targeting misfolded cytosolic proteins for degradation; regulates peptide transport via Cup9p ubiquitination; mutation in human UBR1 causes Johansson-Blizzard Syndrome (JBS)
Saccharomyces cerevisiae (S288c)

Substrate-binding sites of UBR1, the ubiquitin ligase of the N-end rule pathway.

Xia Z, Webster A, Du F, Piatkov K, Ghislain M, Varshavsky A

Substrates of a ubiquitin-dependent proteolytic system called the N-end rule pathway include proteins with destabilizing N-terminal residues. N-recognins, the pathway's ubiquitin ligases, contain three substrate-binding sites. The type-1 site is specific for basic N-terminal residues (Arg, Lys, and His). The type-2 site is specific for bulky hydrophobic N-terminal residues (Trp, Phe, Tyr, Leu, and Ile). We show here that the ... [more]
