Modification of sphingoglycolipids and sulfolipids in kidney cell lines under heat stress: activation of monohexosylceramide synthesis as a ceramide scavenger.

abstract：:In the endoplasmic reticulum (ER), misfolded proteins are retrotranslocated to the cytosol and degraded by the proteasome in a process known as ER-associated degradation (ERAD). Early in this pathway, a proposed lumenal ER lectin, EDEM, recognizes misfolded glycoproteins in the ER, disengages the nascent molecules fro...
