Abstract

Tryptases are serine proteases implicated in asthma and are very highly expressed in human mast cells. They fall into two groups, alpha and beta. Although several related tryptase mRNAs are known, it is unclear which if any are transcripts of separate haploid genes. The studies described here investigated the nature and number of human tryptases and sought possibly novel members of the family. To this end, two human bacterial artificial chromosome (BAC) clones containing tryptase genes were identified and mapped to chromosome 16p13.3, of which approximately 2.2 megabases are syntenic with the part of mouse chromosome 17 containing tryptase genes mouse mast cell protease (mMCP)-6 and -7. Sequencing and restriction mapping suggest that the BACs may partially overlap. Sequenced BAC genes correspond to three known beta-tryptases (betaI, betaII, and betaIII), an alpha-like gene, and a pair of novel hybrid genes related partly to alpha/beta-tryptases and partly to orthologs of mMCP-7. betaII and betaIII, betaI and alphaII, as well as the two mMCP-7-like genes, may be alleles at single loci; in total, there are at least three nonallelic tryptase genes in the isolated BAC clones. DNA blotting and restriction analysis suggest that the BACs include most members of the immediate tryptase family. Thus, chromosome 16p13.3 harbors a cluster of known and previously undescribed members of the tryptase gene family.

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.
