Antibody-based proteomics provides a powerful approach for the functional study of the human proteome involving the systematic generation of protein-specific affinity reagents. We used this strategy to construct a comprehensive, antibody-based protein atlas for expression and localization profiles in 48 normal human tissues and 20 different cancers. Here we(More)
The testis determining factor, SRY, is a DNA binding protein that causes a large distortion of its DNA target sites. We have analysed the biochemical properties of the DNA binding domains (HMG-boxes) of mutant SRY proteins from five patients with complete gonadal dysgenesis. The mutant proteins fall into three categories: two bind and bend DNA almost(More)
The Central Dogma of biology holds, in famously simplified terms, that DNA makes RNA makes proteins, but there is considerable uncertainty regarding the general, genome-wide correlation between levels of RNA and corresponding proteins. Therefore, to assess degrees of this correlation we compared the RNA profiles (determined using both cDNA- and oligo-based(More)
We have cloned three sox genes in zebrafish (Danio rerio), one related to human and chicken SOX21, and two related to mammalian and chicken Sox-11. Zebrafish sox21, sox11A and sox11B transcripts are accumulated in the egg, are present in all cells until gastrulation and become restricted later to the developing central nervous system (CNS); expression in(More)
Vitiligo is a complex, polygenic disorder characterized by patchy loss of skin pigmentation due to abnormal melanocyte function. Both genetic and environmental etiological factors have been proposed for vitiligo and lack of molecular markers renders difficulties to predict development and progression of the disease. Identification of dysregulated genes has(More)
Small conductance calcium-activated potassium (SK) channels are important in controlling neuronal excitability and three SK channels have been identified to date. In the present study, we report the first quantitative analysis of SK1, SK2 and SK3 expression in human brain using TaqMan RT-PCR on a range of human brain and peripheral tissue samples. SK1(More)
Sulfated glycoprotein 2 (SGP-2) is a rat glycoprotein that is particularly abundant in seminal fluid, where it is found associated with the acrosome and the tail of mature spermatozoa; for this reason it has been suggested that it has an important role in spermatogenesis. On the basis of nucleotide sequence homology, it has been proposed that the(More)
The expression of the small conductance calcium-activated potassium channels SK1, SK2 and SK3 was investigated in the TE671 human medulloblastoma cell line using RT-PCR and transcripts were detected only for SK3. Immunodetection experiments confirmed this result, demonstrating the presence of the SK3 protein. This potassium channel was characterised in(More)
Antibody microarrays offer a powerful tool to screen for target proteins in complex samples. Here, we describe an approach for systematic analysis of serum, based on antibodies and using color-coded beads for the creation of antibody arrays in suspension. This method, adapted from planar antibody arrays, offers a fast, flexible, and multiplexed procedure to(More)
