Function

PER_CAEEL Transcriptional repressor which interacts with the promoter region of target genes (PubMed:25032706). Has a specific role in developmental timing where it regulates temporal expression of a number of miRNAs and mRNAs (PubMed:16300753, PubMed:25032706, PubMed:25319259, PubMed:15691769, PubMed:29880558). Controls temporal cell fate transition during embryonic and early larval development by restricting the expression of specific miRNAs, including let-7, miR-48, lin-4, miR-35 and miR-58 (PubMed:24699545, PubMed:25032706, PubMed:25319259, PubMed:15691769, PubMed:29880558). Restricts the accumulation of lin-29 in the hypodermis to the larval L4 stage, thus controlling terminal differentiation of seam cells (PubMed:10550049, PubMed:21471153). Has a role in the miRNA-mediated specification of asymmetric gene expression patterns in gustatory neurons (PubMed:25032706). May also regulate genes involved in other biological processes including transport, small molecule metabolism, and growth (PubMed:25032706). Inhibits dauer formation, by antagonizing daf-12 (PubMed:20843862).[1] [2] [3] [4] [5] [6] [7] [8] [9] Specifically required for maintaining the timing of larval development and molting cycle rhythms.[10]
