Figure 1. Tbx1 T-box sequence comparison and developmental expression of Xtbx1. A: Comparison of the T-box domains of Tbx1 orthologues from various species. Sequence identity is represented by shading and gaps are represented by dashes. Sequence comparison was performed using Clustal at SDSC (http://workbench.sdsc.edu). Hs, Homo sapiens; Mm, Mus musculus; Xl, Xenopus laevis; Dr, Danio rerio; Lf, Lampetra fluviatilis; Bf, Branchiostoma floridae; Ci, Ciona intestinalis; Dm, Drosophila melanogaster (org-1). The XTbx1 sequence has been deposited in Genbank, with accession number AF526274. B: Detection of Xtbx1 mRNA in Xenopus embryos at various stages of development by reverse transcriptase-polymerase chain reaction. The stage of the embryos is indicated above each lane. Xtbx1 is present at low levels as a maternal transcript at stage 7, before zygotic transcription has begun and is then readily detected at all stages tested between 12 and 28. The lane labeled -ve indicates a water-only control. Image published in: Ataliotis P et al. (2005) Copyright © 2005. Image reproduced with permission of the Publisher, John Wiley & Sons.
