Protein

Protein SGT1

Gene

SGT1

Organism
Saccharomyces cerevisiae (strain ATCC 204508 / S288c) (Baker's yeast)
Status
Reviewed - Annotation score: 5 out of 5- Experimental evidence at protein leveli

Functioni

Involved in ubiquitination and subsequent proteasomal degradation of target proteins. Required for both entry into S phase and kinetochore function. Also involved in cyclic AMP (cAMP) pathway, possibly by participating in the assembly or the conformational activation of specific multiprotein complexes.2 Publications
