Abstract

The transcription factor NHR-49 has been extensively studied for its functions in regulating metabolic processes, stress responses, innate immunity and aging. Molecular identification of a gene previously known as , which affects susceptibility of worms to deleterious surface attachment of bacterial biofilms from revealed that is an ochre nonsense allele of . Other severe mutations of also had a Bah phenotype, but deletions affecting 5' isoforms of the gene did not affect biofilm attachment, nor did 3' gain-of-function missense mutations. Other genes ( ) encode GT92 glycosylation factors, predicted to affect surface coat. NHR-49 may act as a positive transcription factor for one or more of these surface glycosylation genes, in contrast to its other roles in regulating metabolic processes.
