Sequencing and analysis of 10,967 full-length cDNA clones from Xenopus laevis and Xenopus tropicalis reveals post-tetraploidization transcriptome remodeling.

Sequencing of full-insert clones from full-length cDNA libraries from both Xenopus laevis and Xenopus tropicalis has been ongoing as part of the Xenopus Gene Collection Initiative. Here we present 10,967 full ORF verified cDNA clones (8049 from X. laevis and 2918 from X.

A mouse atlas of gene expression: large-scale digital gene-expression profiles from precisely defined developing C57BL/6J mouse tissues and cells.

We analyzed 8.55 million LongSAGE tags generated from 72 libraries. Each LongSAGE library was prepared from a different mouse tissue.

Mutations in HFE2 cause iron overload in chromosome 1q-linked juvenile hemochromatosis.

Juvenile hemochromatosis is an early-onset autosomal recessive disorder of iron overload resulting in cardiomyopathy, diabetes and hypogonadism that presents in the teens and early 20s (refs. 1,2). Juvenile hemochromatosis has previously been linked to the centromeric region of chromosome 1q (refs.

Expression and localization of the Mycobacterium tuberculosis protein tyrosine phosphatase PtpA.

The Mycobacterium tuberculosis open reading frame Rv2234 encodes a low molecular weight tyrosine phosphatase named PtpA. Kinetic analyses of PtpA activity reveal that it is capable of dephosphorylation of p-nitrophenyl phosphate, as well as a variety of phosphotyrosine-containing substrates. In contrast, PtpA showed no detectable activity towards substrates containing phosphoserine or -threonine residues.
