Expression of growth/differentiation factor 1 in the nervous system: conservation of a bicistronic structure.

Abstract

Growth/differentiation factor 1 (GDF-1) is a recently described member of the transforming growth factor beta superfamily isolated from a day-8.5 mouse embryo cDNA library. Northern (RNA) analysis of embryonic mRNA detected two GDF-1 transcripts [1.4 kilobases (kb) and 3.0 kb in length] displaying distinct temporal patterns of expression. Only the 3.0-kb transcript was detected in adult tissues, where its expression was restricted almost exclusively to the central nervous system. Comparison of murine and human brain cDNA sequences corresponding to the 3.0-kb transcript revealed high conservation of two nonoverlapping open reading frames with poor conservation of the intervening spacer region and the putative 5' and 3' untranslated sequences. By immunohistochemical analysis, the protein encoded by the downstream open reading frame (GDF-1) was detected exclusively in the brain, spinal cord, and peripheral nerves in day-14.5 mouse embryos. The upstream open reading frame encodes a protein of unknown function containing multiple putative membrane-spanning domains. These findings raise the possibility that this mRNA may give rise to two different proteins.

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.
