TLDR Desmoglein 4 is controlled by specific proteins that affect hair growth.
The study investigated the transcriptional regulation of Desmoglein 4 (DSG4), a key desmosomal cadherin in the hair shaft cortex, by transcription factors known to regulate hair keratin and keratin-associated protein (KAP) expression. The researchers found that transcription factors HOXC13, LEF1, and FOXN1 repressed DSG4 transcription. Additionally, they provided both in vitro and in vivo evidence suggesting that the Notch pathway is involved in the activation and/or maintenance of DSG4 expression in the hair follicle. Mutations in hair keratins or DSG4 were linked to beaded hair phenotypes, such as monilethrix.
