RT essential role for the pro-region.";
RL Dev. Biol. 265:155-168(2004).
CC -!- FUNCTION: Exhibits mesoderm-dorsalizing activity and neural-inducing
CC activity, but lacks mesoderm-inducing activity. Regulates the
CC expression of specific mesodermal and neural genes. Induces convergent
CC extension movements at the embryonic midline by activating the fgf
CC signaling pathway to induce t/bra expression in the organizer region.
CC Acts with wnt11 to induce Spemann organizer cells and induce axis
CC formation (By similarity). The unprocessed protein antagonizes bmp-
CC signaling. {ECO:0000250|UniProtKB:Q91609, ECO:0000269|PubMed:14697360}.
CC -!- SUBUNIT: Monomer (By similarity). The propeptide region interacts with
CC bmp4 in a non-covalent manner. {ECO:0000250,
CC ECO:0000269|PubMed:14697360}.
CC -!- SUBCELLULAR LOCATION: Secreted {ECO:0000250|UniProtKB:Q91620}.
CC -!- TISSUE SPECIFICITY: Expressed in the dorsal marginal region of late
CC blastula, becoming restricted to the Spemann organizer at the early
CC gastrula stage. {ECO:0000269|PubMed:14697360}.
CC -!- DEVELOPMENTAL STAGE: First detected at the blastula stage (stage 8).
CC Expression peaks through the mid-blastula (stage 8.5) to early gastrula
CC (stage 10) and then decreases during gastrulation.
CC {ECO:0000269|PubMed:14697360}.
CC -!- DOMAIN: The propeptide region is both necessary and sufficient for bmp-
CC inhibitory activity. The propeptide region and the N- and C-terminal
CC thirds of the mature protein are necessary for neural induction
CC activity. Although cleavage doesn't appear essential for activity,
CC residues surrounding the cleavage site are necessary for activity (By
CC similarity). {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the TGF-beta family. {ECO:0000255}.
