Abstract

C. elegans SET-9 and SET-26 are highly homologous paralogs that share redundant functions in germline development, but SET-26 alone plays a key role in longevity and heat stress response. SET-26 is broadly expressed, but SET-9 is only detectable in the germline, which likely account for their different biological roles. SET-9 and SET-26 bind to H3K4me3 with adjacent acetylation marks in vitroand in vivo. In the soma, SET-26 acts through DAF-16 to modulate longevity. In the germline, SET-9 and SET-26 restrict H3K4me3 domains around SET-9 and SET-26 binding sites, and regulate the expression of specific target genes, with critical consequence on germline development. SET-9 and SET-26 are highly conserved and our findings provide new insights into the critical role of these H3K4me3 readers in germline function and longevity.
