A conserved sequence motif has been identified in a number of signaling subunits associated with hematopoietic cell antigen receptors. Here, we characterize signaling by a 17 amino acid motif that is triplicated in the T cell antigen receptor zeta chain. Analysis of zeta truncations and constructs containing the isolated motif demonstrates that this motif is sufficient for the induction of both...
Camelina sativa is an oilseed with desirable agronomic and oil-quality attributes for a viable industrial oil platform crop. Here we generate the first chromosome-scale high-quality reference genome sequence for C. sativa and annotated 89,418 protein-coding genes, representing a whole-genome triplication event relative to the crucifer model Arabidopsis thaliana. C. sativa represents the first c...
TCK, the creatine kinase (ATP:creatine N-phosphotransferase) from sperm flagella of the sea urchin Strongylocentrotus purpuratus, is a Mr 145,000 axonemal protein that is employed in energy transport. Its amino acid sequence was obtained by analysis of fragments from cyanogen bromide digestion and by sequencing cDNA clones from two sea urchin testis libraries. TCK contains three complete but no...
Down syndrome (DS) results from complete or partial triplication of human chromosome 21. It is assumed that the neurological and other symptoms are caused by the overexpression of genes on chromosome 21, but this hypothesis has not yet been assessed on a chromosome-wide basis. Here we show that expression of genes localized to chromosome 21 is globally up-regulated in human fetal trisomy 21 cas...
