Here we show that presenilin-1 (PS1), a protein involved in Alzheimer's disease, binds directly to epithelial cadherin (E-cadherin). This binding is mediated by the large cytoplasmic loop of PS1 and requires the membrane-proximal cytoplasmic sequence 604-615 of mature E-cadherin. This sequence is also required for E-cadherin binding of protein p120, a known(More)
vrille and Par domain protein 1 (Pdp1) epsilon constitute the second transcriptional feedback loop in Drosophila circadian clock system. Their rhythmic expression is controlled by Drosophila Clock (dClk) gene, and they feed back to negatively and positively, respectively, regulate the oscillating transcription from dClk gene. In this study, we characterized(More)
