Fig. 1From: Mouse Obox and Crxos modulate preimplantation transcriptional profiles revealing similarity between paralogous mouse and human homeobox genesETCHbox genes in human and mouse. The ETCHbox group of homeobox genes has six members: Leutx, Tprx1, Tprx2, Dprx, Argfx and Pargfx. In human, Pargfx has been lost in evolution. In mouse, only Tprx1 and Tprx2 orthologues remain and are referred to as Crxos and Obox, respectively; each has undergone sequence divergence and gene duplicationBack to article page
