Lysine 136-142 presenilin 2 Homo sapiens 60-72 17614368-4 2007 Mutation of two lysine residues in the PS2-loop region suggested that ubiquitination is not required for interaction with ubiquilin-1 and may, in fact, even negatively regulate the interaction. Lysine 16-22 presenilin 2 Homo sapiens 39-42 17614368-6 2007 Instead, we found that the mutation of either one of the two lysine residues in the carboxyl terminus of PS2 or the proline residues in the highly conserved PALP motif in this region results in destabilization of the mutant PS2 polypeptides because of increased degradation by the proteasome.

Cholesterol 11-22 presenilin 2 Homo sapiens 62-65 17401156-7 2006 In the absence of exogenous lipids, cell PS1 and PS2 expression was induced by LDL and by lysosomal sequestration of cholesterol. Cholesterol 117-128 presenilin 2 Homo sapiens 49-52 17401156-8 2006 However, a different pattern of induction of presenilin gene expression was observed in the latter condition, suggesting that lysosomal cholesterol levels are strong inducers of PS2 transcription.
