Bone morphogenetic protein 4; Negatively regulates the structure and function of the limb apical ectodermal ridge.

Forkhead box protein D3; Binds to the consensus sequence 5'-A[AT]T[AG]TTTGTTT-3' and acts as a transcriptional repressor. Also acts as a transcriptional activator. Promotes development of neural crest cells from neural tube progenitors. Restricts neural progenitor cells to the neural crest lineage while suppressing interneuron differentiation. Required for maintenance of pluripotent cells in the pre-implantation and peri- implantation stages of embryogenesis.

Zinc finger protein ZIC 1; Acts as a transcriptional activator. Involved in neurogenesis. Plays important roles in the early stage of organogenesis of the CNS, as well as during dorsal spinal cord development and maturation of the cerebellum. Binds to the minimal GLI-consensus sequence 5'-TGGGTGGTC-3' (By similarity).

HMG box domain-containing protein.

Uncharacterized protein.

Transcription factor SOX-9; Transcription factor that selectively activates enhancer through its interaction with a DNA-binding partner factor. Activates enhancer of COL2A1 through its binding with DNA sequence 5'-ATTCAT-3'. In response to bone morphogenetic protein stimulus, phosphorylation is induced and then sumoylation, allowing cooperation with SNAI2 to trigger neural crest delamination. Functions at the level of mesenchymal cell condensation by inducing cartilage development in limbs and by changing the aggregation properties of limb mesenchymal cells. Regulates the cell fate dec [...]

Fibroblast growth factor 8; Plays an important role in the regulation of embryonic development, cell proliferation, cell differentiation and cell migration. Involved in initiation, outgrowth and patterning of the limbs; Belongs to the heparin-binding growth factors family.

Sonic hedgehog protein N-product; [Sonic hedgehog protein]: The C-terminal part of the sonic hedgehog protein precursor displays an autoproteolysis and a cholesterol transferase activity (By similarity). Both activities result in the cleavage of the full-length protein into two parts (ShhN and ShhC) followed by the covalent attachment of a cholesterol moiety to the C-terminal of the newly generated ShhN (By similarity). Both activities occur in the reticulum endoplasmic (By similarity). Once cleaved, ShhC is degraded in the endoplasmic reticulum (By similarity).

Transcription factor SOX-10; Transcription factor that plays a central role in developing and mature glia. Specifically activates expression of myelin genes, during oligodendrocyte (OL) maturation, thereby playing a central role in oligodendrocyte maturation and CNS myelination.
