The human AdipoR2 protein and its C. elegans homolog PAQR-2 are multi-pass plasma membrane proteins that protect cells against membrane rigidification. We seek to better understand the mechanisms by which these proteins can promote the synthesis and incorporation of membrane-fluidizing unsaturated f...

Dicer is a deeply conserved endoribonuclease with key functions in small RNA biogenesis. Here we employed PAR-CLIP/iPAR-CLIP to identify direct Dicer binding sites in the transcriptomes of human cells and C.elegans. We found hundreds of novel miRNAs and non-canonical Dicer substrates with high sensi...

Regulation of presenilin genes. Presenilins are intramembrane aspartic proteases. These proteases are critical proteins in pathogenesis of Alzheimer's disease. The function of recently identified presenilin-homologous proteases (IMPAS or SPP)s is unknown. Our preliminary data in C.elegans model sugg...

Readthrough into the 3′ untranslated region (3′UTR) of the mRNA results in the production of aberrant proteins. Metazoans efficiently clear readthrough proteins, but the underlying mechanisms remain unknown. Here, we show in C. elegans and mammalian cells that readthrough proteins are targeted by a ...
