The NSL complex is required for piRNA production from telomeric clusters.

The NSL complex is a transcriptional activator. Germline-specific knockdown of NSL complex subunits NSL1, NSL2, and NSL3 results in reduced piRNA production from a subset of bidirectional piRNA clusters, accompanied by widespread transposon derepression. The piRNAs most transcriptionally affected by NSL2 and NSL1 RNAi map to telomeric piRNA clusters.

The NSL complex-mediated nucleosome landscape is required to maintain transcription fidelity and suppression of transcription noise.

Nucleosomal organization at gene promoters is critical for transcription, with a nucleosome-depleted region (NDR) at transcription start sites (TSSs) being required for transcription initiation. How NDRs and the precise positioning of the +1 nucleosomes are maintained on active genes remains unclear. Here, we report that the nonspecific lethal (NSL) complex is necessary to maintain this stereotypical nucleosomal organization at promoters.

Discrete roles of trehalose and Hsp104 in inhibition of protein aggregation in yeast cells.

Heat shock response (HSR) is an important element of cellular homeostasis. In yeast, HSR comprises of the heat shock proteins (Hsps) and the osmolytes trehalose and glycerol. The respective roles of trehalose and Hsp104 in regulating protein aggregation remain ambiguous.
