Summary: Enables RNA polymerase II-specific DNA-binding transcription factor binding activity. Involved in negative regulation of dauer larval development; negative regulation of miRNA transcription; and regulation of development, heterochronic. Located in cytoplasm and nucleus. Is expressed in several structures, including H1L.app; H1R.app; H2L.ppp; hypodermal cell; and pharynx. Human ortholog(s) of this gene implicated in advanced sleep phase syndrome; advanced sleep phase syndrome 1; alcohol dependence; cocaine dependence; and fetal alcohol spectrum disorder. Orthologous to human PER1 (period circadian regulator 1) and PER2 (period circadian regulator 2). [provided by Alliance of Genome Resources, Dec 2024]

A key function of lin-42 in developmental timing is to dampen pri-miRNAs levels, preventing their premature expression as mature miRNAs.
Title: Caenorhabditis elegans period homolog lin-42 regulates the timing of heterochronic miRNA expression.
lin-42 functions to negatively regulate the transcriptional output of multiple miRNAs and mRNAs and therefore coordinates the expression levels of genes that dictate temporal cell fate

Inactivation of the heterochronic gene lin-42a leads to arrhythmic molts and abnormal epidermal stem cell dynamics. Oscillatory expression in the epidermis peaks during the molts; forced expression leads to anachronistic larval molts and adult lethargy.

Title: The C. elegans developmental timing protein LIN-42 regulates diapause in response to environmental cues.
LIN-42 has a dynamic expression pattern; its levels oscillate relative to the molts during postembryonic development.
