Nuclear localization signals, DNA binding, and transactivation properties of quail Pax-6 (Pax-QNR) isoforms.
We reported previously the characterization of Pax-QNR/Pax-6 products expressed in the avian neuroretina. Five proteins (48, 46, 43, 33, and 32 kDa) were characterized, among which the 33 and 32 kDa proteins are devoid of the paired domain. In contrast to the 48-kDa (containing an alternative paired exon 4a) and 46-kDa proteins exclusively located in the nucleus, the 43- (in which the paired ex...
متن کاملIdentification of a Pax paired domain recognition sequence and evidence for DNA-dependent conformational changes.
Pax genes encode a family of developmentally regulated transcription factors that have been implicated in a number of human and murine congenital disorders, as well as in tumorigenesis (Gruss, P., and Walther, C. (1992) Cell 69, 719-722; Hill, R., and van Heyningen, V. (1992) Trends Genet. 8, 119-120; Chalepakis, G., Tremblay, P., and Gruss, P. (1992) J. Cell Sci. Suppl. 16, 61-67; Maulbecker, ...
متن کاملDNA-binding characteristics of cnidarian Pax-C and Pax-B proteins in vivo and in vitro: no simple relationship with the Pax-6 and Pax-2/5/8 classes.
Cnidarians are the simplest animals in which distinct eyes are present. We have previously suggested that cnidarian Pax-Cam might represent a precursor of the Pax-6 class. Here we show that when expressed in Drosophila imaginal discs, Pax-Cam chimeric proteins containing the C-terminal region of EY were capable of eye induction and driving expression of a reporter gene under the control of a kn...
متن کاملExpression of the paired-box genes Pax-1 and Pax-9 in limb skeleton development.
Vertebrate Pax genes encode a family of transcription factors that play important roles in embryonic patterning and morphogenesis. Two closely related Pax genes, Pax-1 and Pax-9, are associated with early axial and limb skeleton development. To investigate the role of these genes in cartilage formation we have examined the expression profiles of Pax-1 and Pax-9 in developing chick limb mesenchy...
متن کاملPAX-6 in development and evolution.
Pax-6 is a member of the Pax gene class and encodes a protein containing a paired domain and a homeodomain. The molecular characterization of Pax-6 genes from species of different animal phyla and the analysis of Pax-6 function in the developing eyes and central nervous system of vertebrates, Drosophila melanogaster, and Caenorhabditis elegans suggest that Pax-6 homologues share conserved funct...
