eukaryotes, genes are packed into chromatin. It is becoming clear
that, rather than just being a DNA-packaging vehicle, chromatin is a
dynamic and active participant in regulating transcription of the
Our group has an interest in the function of a particular protein, ATRX, that appears to play a role in regulating gene expression through its interaction with chromatin. It belongs to the SNF2 family of DNA-dependent ATPases and putative helicases. Members of this family appear to be involved in a wide range of cellular functions but a common thread is their ability to remodel chromatin.
Mutations in the ATRX gene give rise to a form of syndromal mental retardation known as X-linked alpha thalassaemia mental retardation (ATR-X) syndrome.
HbH inclusions in alpha thalassaemia
It is characterised by severe learning difficulties, a characteristic facial appearance, abnormalities of genital development and alpha thalassaemia. Somatic mutations in ATRX are found in an acquired form of alpha thalassaemia associated with myelodysplasia. In these two conditions, the alpha thalassaemia, which is a form of anaemia resulting from defective production of alpha globin, is due to down-regulation of alpha globin gene expression and this points to a role of ATRX in regulating transcription.
Child with ATR-X syndrome
The overall aim of this programme is to determine the role of such proteins in the regulation of gene expression and their involvement in human disease.
