Background

ARX (Aristaless-Related homeoboX protein) is a 56-62 kDa member of the aristaless subfamily, paired homeobox family of proteins. In the nervous system, it is expressed in embryonic telencephalon plus adult cortical GABAergic neurons and differentiating neuronal stem cells; in the pancreas, it promotes the differentiation of alpha -cells at the expense of beta -cells. Human ARX is a 562 amino acid (aa) transcriptional repressor. It contains an octapeptide motif that binds Groucho proteins (aa 27‑34), an NLS (aa 82-89), one Ala-rich region (aa 100-155), an acidic/Glu-rich region (aa 224-253), a DNA-binding homeodomain with an embedded NLS (aa 328‑387), one Pro-rich segment that binds CtBP1 (aa 395-459) and a C-terminal Aristaless domain (aa 530-543). There are mutations that show poly-Ala expansions in the N-terminus (aa 115-155), often associated with developmental abnormalities. Over aa 1-100, human ARX shares 97% aa identity with mouse ARX.
