ATRX Antibody
Clone: GR244
As a member of the Snf2 family of helicase/ATPases, ATRX helps to initiate transcription and replication and contributes to the ATP-dependent remodelling of the nucleosome structure. ATRX has a PHD zinc finger motif structurally. ATRX is distributed differently in the nucleus and is controlled during the cell cycle. ATRX localises with condensed chromatin during mitosis, although it mostly interacts with the nuclear matrix during interphase. Phosphorylation quickly causes this shift of ATRX to the short arms of the human acrocentric chromosomes at the start of M phase. It then mediates chromosomal segregation by openly complexing with heterochromatin protein 1 α. High rates of severe X-linked syndromal mental retardation connected to αthalassemia or ATRX syndrome are correlated with mutations in the ATRX gene.
