Transcription factor SOX-6 is a protein that in humans is encoded by the SOX6 gene.[1][2]


The SOX gene family encodes a group of transcription factors defined by the conserved high mobility group (HMG) DNA-binding domain. Unlike most transcription factors, SOX transcription factors bind to the minor groove of DNA, causing a 70- to 85-degree bend and introducing local conformational changes.[supplied by OMIM][2]


SOX6 has been shown to interact with CTBP2[3] and CENPK.[4]

It has also been demonstrated that SOX6 protein accumulates in the differentiating human erythrocytes, and then is able to downregulate its own transcription, by directly binding to an evolutionarily conserved consensus sequences located near SOX6 transcriptional start site.[5]

Sox6 appears to have a crucial role in the transcriptional regulation of globin genes, and in directing the terminal differentiation of red blood cells.[6]
