Abstract

The transforming growth factor beta (TGF-beta)-related products of the Xenopus Vg-1 and Drosophila decapentaplegic (DPP) genes have been implicated in the control of growth and differentiation during embryogenesis. We have isolated a mouse cDNA, Vgr-1, that encodes a polypeptide structurally related to Xenopus Vg-1. Sequence comparisons indicate that the Vgr-1 protein belongs to a family of DPP-like gene products within the TGF-beta superfamily. The levels of Vgr-1 RNA were determined in embryos and tissues isolated at various stages of development. A 3.5-kilobase mRNA increases throughout development and into adulthood in many tissues and in F9 teratocarcinoma cells differentiating into endoderm in response to retinoic acid and cAMP. The amino acid homologies and patterns of expression suggest that, like the DPP gene product, Vgr-1 plays a role at various stages of development.

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.
