Official Symbol: hlh-8
Official Full Name: Twist-related protein
Primary source: WormBase:WBGene00001953
Locus tag: CELE_C02B8.4
See related: AllianceGenome:WB:WBGene00001953
Gene type: protein coding
RefSeq status: REVIEWED
Organism: Caenorhabditis elegans (strain: Bristol N2)
Lineage: Eukaryota; Metazoa; Ecdysozoa; Nematoda; Chromadorea; Rhabditida; Rhabditina; Rhabditomorpha; Rhabditoidea; Rhabditidae; Peloderinae; Caenorhabditis
Summary: Predicted to enable DNA-binding transcription factor activity, RNA polymerase II-specific and RNA polymerase II transcription regulatory region sequence-specific DNA binding activity. Involved in mesodermal cell fate specification; positive regulation of transcription by RNA polymerase II; and vulval cell fate specification. Predicted to be located in nucleus. Is expressed in several structures, including M cell; M.dlpa male; M.drpa male; anal depressor muscle; and body muscle cell. Used to study Saethre-Chotzen syndrome. Human ortholog(s) of this gene implicated in Barber-Say syndrome; Sweeney-Cox syndrome; ablepharon macrostomia syndrome; breast cancer (multiple); and synostosis (multiple). Orthologous to several human genes including TWIST2 (twist family bHLH transcription factor 2). [provided by Alliance of Genome Resources, Dec 2024]

What's a GeneRIF?

A Twist-Box domain of the C. elegans Twist homolog, HLH-8, plays a complex role in transcriptional regulation.
Title: A Twist-Box domain of the C. elegans Twist homolog, HLH-8, plays a complex role in transcriptional regulation.
These results support a model whereby HLH-8/HLH-8 homodimers function in M lineage patterning and enteric muscles and HLH-8/HLH-2 heterodimers function in the M-derived vulval muscles.
Title: Distinct Caenorhabditis elegans HLH-8/twist-containing dimers function in the mesoderm.
hlh-8 expression in differentiated mesodermal cells is controlled by two well-conserved E box elements in the large first intron
Title: C. elegans twist gene expression in differentiated cell types is controlled by autoregulation through intron elements.
9 genes were defined as novel CeTwist and CeE/DA targets
