The authors found that BMP2b and Chordin diffuse and rapidly form extracellular protein gradients, Chordin does not modulate the diffusivity or distribution of BMP2b, and Chordin is not required to establish peak levels of BMP signaling.

activation of the FGF signaling pathway induces the formation of a dorsal axis with a complete head structure through the expression of chd and subsequent maintenance of dkk1b expression levels.
Title: Chordin and dickkopf-1b are essential for the formation of head structures through activation of the FGF signaling pathway in zebrafish.
Binding of CV2 to Chordin promotes BMP-2 signaling.
Title: Binding between Crossveinless-2 and Chordin von Willebrand factor type C domains promotes BMP signaling by blocking Chordin activity.
Targeted knockdown of Sox17 and Chd in dorsal forerunner cells led to aberrant Left-Right (L-R) asymmetry establishment, as visualized by the expression of southpaw and lefty, and heart and pancreas placement in the embryo.
Title: Sox17 and chordin are required for formation of Kupffer's vesicle and left-right asymmetry determination in zebrafish.
Chl, like Chd, dorsalizes embryos upon overexpression and is cleaved by BMP1; loss-of-function experiments show Chl serves as a BMP antagonist with functions that overlap and are redundant with those of Chd in forming the dorsoventral axis.
Title: Zebrafish chordin-like and chordin are functionally redundant in regulating patterning of the dorsoventral axis.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
