Abstract

The invected and engrailed genes are juxtaposed in the Drosophila genome and are closely related in sequence and pattern of expression. The structure of the most abundant invected transcript was defined by obtaining the full-length cDNA sequence and by S1 nuclease sensitivity and primer extension studies; a partial sequence of the invected gene was determined; and the developmental profile of invected expression was characterized by Northern analysis and by in situ localization. The invected gene, like the engrailed gene, is expressed in the embryonic and larval cells of the posterior developmental compartments and in the embryonic hindgut, clypeolabrum, and nervous system. Like the engrailed gene, the invected gene can encode a protein of approximately 60 kD that contains a homeo box near its carboxyl terminus; indeed, a sequence of 117 amino acids in the carboxy-terminal region of both proteins is almost identical. The developmental role of the invected gene is not known.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Microexons, defined as 3-27 nucleotide exons, have been largely missed by genome annotations and transcriptome profiling studies, especially those shorter than 15 nucleotides.

    “In particular, microexons (Beachy et al., 1985; Coleman et al., 1987), defined here as 3-27 nucleotide (nt)-long exons, have been largely missed by genome annotations and transcriptome profiling studies (Volfovsky et al., 2003; Wu et al., 2013; Wu and Watanabe, 2005). This is especially true for microexons shorter than 15 nts.”

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.
