NCIt definition : Human TAF4 wild-type allele is located in the vicinity of 20q13.33 and is approximately
91 kb in length. This allele, which encodes transcription initiation factor TFIID
subunit 4 protein, plays a role in the potentiation of transcriptional activation
by retinoic acid, vitamin D3 and thyroid hormone.;
NCIt note : The TAF4 gene product plays a role in the regulation of transcription factors that
contain glutamine-rich sequences. Aberrant binding of the TAF4 gene product to proteins
that contain expanded polyglutamine regions is involved in the pathology of several
neurodegenerative disorders referred to as polyglutamine diseases, which includes
Huntington disease and several forms of spinocerebellar ataxia. (Entrez Gene and OMIM);
