Saccharomyces cerevisiae (S288c)


putative ubiquitin-protein ligase ASI1, YMR119W
Subunit of the nuclear inner membrane Asi ubiquitin ligase complex; Asi complex targets both misfolded proteins and regulators of sterol biosynthesis for ubiquitin-mediated degradation; acts with Asi2p and Asi3p to ensure the fidelity of SPS-sensor signalling by targeting latent unprocessed forms of Stp1p and Stp2p and maintains the repressed state of gene expression in the absence of inducing amino acids; ASI1 has a paralog, ASI3, that arose from the whole genome duplication
