Five years on the wings of fork head
- E. Kaufmann, W. Knöchel
- Biology, Medicine
- Mechanisms of Development
- 1 June 1996
Since its discovery five years ago the conserved family of fork head/HNF-3-related transcription factors has gained increasing importance for the analysis of gene regulatory mechanisms during… Expand
SHARP is a novel component of the Notch/RBP-Jkappa signalling pathway.
- F. Oswald, U. Kostezka, +9 authors R. Schmid
- Medicine
- The EMBO journal
- 2002
Notch proteins are the receptors for an evolutionarily highly conserved signalling pathway that regulates numerous cell fate decisions during development. Signal transduction involves the… Expand
Transcriptional regulation of BMP4 synexpression in transgenic Xenopus
- E. Karaulanov, W. Knöchel, C. Niehrs
- Biology, Medicine
- The EMBO journal
- 25 February 2004
Synexpression groups are genetic modules composed of genes that share both a complex expression pattern and the biological process in which they function. Here we investigate the regulation of BMP4… Expand
Overexpression of the transcriptional repressor FoxD3 prevents neural crest formation in Xenopus embryos
- Barbara S. Pohl, W. Knöchel
- Biology, Medicine
- Mechanisms of Development
- 1 May 2001
Xenopus FoxD3 (XFD-6) is an intron-less gene initially expressed within the Spemann organizer and later in premigratory neural crest cells. Based upon sequence and expression pattern comparisons, it… Expand
Axial patterning in snakes and caecilians: evidence for an alternative interpretation of the Hox code.
- J. Woltering, F. Vonk, +7 authors M. K. Richardson
- Biology, Medicine
- Developmental biology
- 1 August 2009
It is generally assumed that the characteristic deregionalized body plan of species with a snake-like morphology evolved through a corresponding homogenization of Hox gene expression domains along… Expand
SHARP is a novel component of the Notch/RBP‐Jκ signalling pathway
- F. Oswald, U. Kostezka, +9 authors R. Schmid
- Biology
- 15 October 2002
Notch proteins are the receptors for an evolutionarily highly conserved signalling pathway that regulates numerous cell fate decisions during development. Signal transduction involves the… Expand
Bone morphogenetic protein 2 in the early development of Xenopus laevis
- J. Clement, P. Fettes, S. Knöchel, J. Lef, W. Knöchel
- Biology, Medicine
- Mechanisms of Development
- 1 August 1995
The temporal and spatial transcription patterns of the Xenopus laevis Bone morphogenetic protein 2 (BMP-2) gene have been investigated. Unlike the closely related BMP-4 gene, the BMP-2 gene is… Expand
Xenopus POU factors of subclass V inhibit activin/nodal signaling during gastrulation
- Y. Cao, D. Siegel, W. Knöchel
- Biology, Medicine
- Mechanisms of Development
- 1 August 2006
Three POU factors of subclass V, Oct-25, Oct-60 and Oct-91 are expressed in Xenopus oocytes and early embryos. We here demonstrate that vegetal overexpression of Oct-25, Oct-60, Oct-91 or mammalian… Expand
Activin A induced expression of a fork head related gene in posterior chordamesoderm (notochord) of Xenopus laevis embryos.
- S. Knöchel, J. Lef, +4 authors W. Knöchel
- Medicine
- Mechanisms of development
- 1992
A gene family encoding the fork head/HNF-3 domain has been identified in the South African clawed frog, Xenopus laevis. Screening of genomic DNA and gastrula stage derived cDNA libraries with a DNA… Expand
The Drosophila fork head domain protein crocodile is required for the establishment of head structures.
- U. Häcker, E. Kaufmann, C. Hartmann, G. Jürgens, W. Knöchel, H. Jäckle
- Biology, Medicine
- The EMBO journal
- 1 November 1995
The fork head (fkh) domain defines the DNA‐binding region of a family of transcription factors which has been implicated in regulating cell fate decisions across species lines. We have cloned and… Expand
