The particular gene set in which we are interested is the one encoding ribosomal RNAs. Ribosomal RNA genes were the first eukaryotic genes to be isolated in pure form, and these genes are among the most extensively studied. Despite this, we do not yet have a detailed molecular understanding as to the molecular mode of regulation for this gene Author: Jack C. Vaughn, Hannelore T. Koller, Kathleen A. Frondorf, Patricia D.

Structure and expression of "Xenopus borealis" actin genes by Gareth S. Cross Download PDF EPUB FB2

Two cloned Eco RI fragments have been isolated from a Xenopus borealis genomic library in phage lambda, using an actin cDNA clone as a probe.

Both fragments have been restriction-mapped and partially sequenced. As a result of this, one fragment, kb in size, has been found to encode an amino acid sequence identical to the first amino acids of the mammalian cardiac muscle actin Author: Gareth S.

Cross. The structure and expression of Xenopus borealis actin genes These data suggest that vertebrate muscle and cytoskeletal actin genes became separate before the divergence of amphibians from the rest of the vertebrates.

Primer extension has also been used to study the expression of actin genes in several laevis non-muscle tissues, as well Author: Gareth S. Cross. We have sequenced the coding and leader regions, as well as part of the 3' untranslated region, of a Xenopus borealis type 1 cytoskeletal actin gene [defined according to the arrangement of acidic residues at the N-terminus; Vandekerckhove et al.

A comparison with the corresponding genes from X. laevis reveals that the BMP-4 genes are conserved at a higher extent than the BMP-2 genes. This is especially evident for the intron sequences, but is also reflected by the exon by: A processed gene potentially coding for a sarcomeric actin has been identified in Xenopus laevis and in the more primitive species X.

Two species of Xenopus are regularly used by biologists, Xenopus laevis and Xenopus tropicalis. Both species are fully aquatic, and are easy to maintain in captivity.

Alternating domains of XKrox expression appear in the early neurula, later correspond to r3 and r5, and persist until late tadpole stages. In contrast to this conserved spatial expression in rhombomeres, we find a pattern in the neural crest of Xenopus that appears different from that found in the mouse: expression occurs in crest that.The intron/exon structure is typical of vertebrate skeletal-actin genes, as is the possession of multiple copies of three serum-response elements in the promoter of this gene.
