Abstract

Osteogenic protein-2, OP-2, a new member of the transforming growth factor-beta (TGF-beta) superfamily, closely related to the osteogenic/bone morphogenetic proteins, was discovered in mouse embryo and human hippocampus cDNA libraries. The TGF-beta domain of OP-2 shows 74% identity to OP-1, 75% to Vgr-1, and 76% to BMP-5, hence OP-2 may also have bone inductive activity. The genomic locus of OP-2 has seven exons, like OP-1, and spans more than 27 kilobases (kb). In the C-terminal TGF-beta domain, OP-2 has a unique additional cysteine. Mouse embryos express relatively high levels of OP-2 mRNA at 8 days, two species of 3 and 5 kb. A careful study of mRNA expression of the osteogenic proteins in specific organs revealed discrete mRNA species for BMP-3, BMP-4, BMP-5, and BMP-6/Vgr-1 in lung or liver of young and adult mice. OP-1 is expressed in kidney; however, OP-2 and BMP-2 mRNAs were not detected in any organs studied, suggesting an early developmental role.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
