NCIt synonyms : SIX Homeobox 3 wt Allele; HPE2; Sine Oculis Homeobox, Drosophila, Homolog of, 3 Gene;
NCIt definition : Human SIX3 wild-type allele is located within 2p16-p21 and is approximately 4 kb in
length. This allele, which encodes homeobox protein SIX3, plays a role in retinal
development. Mutations in this gene are associated with holoprosencephaly 2.;
NCIt note : Six3 efficiently competes with Cdt1 directly to bind to geminin, which reveals how
Six3 can promote cell proliferation without transcription. The transcription factor
Six3 and the replication-initiation inhibitor geminin act antagonistically to control
the balance between proliferation and differentiation during early vertebrate eye
development. (Nature 2004;427: 745-9.);
