Generic protein structure example

YY1 (Yin Yang 1)[1] is a transcriptional repressor protein in humans that is encoded by the YY1 gene.[2][3]

Function

YY1 is a ubiquitously distributed transcription factor belonging to the GLI-Kruppel class of zinc finger proteins. The protein is involved in repressing and activating a diverse number of promoters. Hence, the YY in the name stands for "yin-yang." YY1 may direct histone deacetylases and histone acetyltransferases to a promoter in order to activate or repress the promoter, thus implicating histone modification in the function of YY1.[4] YY1 promotes enhancer-promoter chromatin loops by forming dimers and promoting DNA interactions. Its dysregulation disrupts enhancer-promoter loops and gene expression.[5][6]

Clinical significance

YY1 heterozygous deletions, missense, and nonsense mutations cause Gabriele-DeVries syndrome (GADEVS),[7][8] an autosomal dominant neurodevelopmental disorder characterized by intellectual disability, dysmorphic facial features, feeding problems, intrauterine growth restriction, variable cognitive impairment, behavioral problems and other congenital malformations.[6] A website is available in order to collect and share clinical information between clinicians and the families of affected individuals.[9]

Interactions

YY1 has been shown to interact with:
