Tetrapod fore-and hindlimbs have evolved from the pectoral and pelvic fins of an ancient vertebrate ancestor. In this ancestor, the pectoral fin appears to have arisen following the rostral homeotic recapitulation of an existing pelvic appendage (Tabin and Laufer (1993), Nature 361, 692-693). Thus the basic appendage outgrowth program is reiterated in both(More)
T-box genes encode putative transcription factors implicated in diverse developmental processes (Papaioannou, V.E. and Silver, L.M., 1998. BioEssays 20, 9-19). We have previously reported the embryonic expression patterns of T-box genes in mice (Chapman, D.L., Garvey, N., Hancock, S., Alexiou, M., Agulnik, S.I., Gibson-Brown, J.J., Cebra-Thomas, J., Bollag,(More)
The T-box genes comprise an ancient family of putative transcription factors conserved across species as divergent as Mus musculus and Caenorhabditis elegans. All T-box gene products are characterized by a novel 174-186-amino acid DNA binding domain called the T-box that was first discovered in the polypeptide products of the mouse T locus and the(More)
The T-box gene family has been conserved throughout metazoan evolution. The genes code for putative transcription factors which share a uniquely defining DNA binding domain, known as the T-box ([Bollag et al., 1994]). They are implicated in the control of diverse developmental processes by their highly specific expression patterns throughout gastrulation(More)
The T-box motif is present in a family of genes whose structural features and expression patterns support their involvement in developmental gene regulation. Previously, sequence comparisons among the T-box domains of ten vertebrate and invertebrate T-box (Tbx) genes established a phylogenetic tree with three major branches. The Tbx2-related branch includes(More)
The classification of the African spiny mice (genus Acomys) within the Muridae family of rodents has been fraught with controversy. Morphological data suggest a close affinity between this group and true old world mice of the genus Mus. However, the combined results of immunological, biochemical, and DNA melting studies suggest that spiny mice should not(More)
