1 Genome-wide association studies have proven to be highly effective at defining relationships between single nucleotide poly-morphisms (SNPs) and clinical phenotypes in complex diseases. Establishing a mechanistic link between a noncoding SNP and the clinical outcome is a significant hurdle in translating associations into biological insight. We(More)
Methylation of specific lysine residues in core histone proteins is essential for embryonic development and can impart active and inactive epigenetic marks on chromatin domains. The ubiquitous nuclear protein PTIP is encoded by the Paxip1 gene and is an essential component of a histone H3 lysine 4 (H3K4) methyltransferase complex conserved in metazoans. In(More)
During kidney development, Pax2 and Pax8 are expressed very early in the mammalian nephric duct and both precede the expression of receptor tyrosine kinase, c-Ret. However, in Pax2-/- mutant mice, expression of c-Ret is lost after embryonic day 10.5. As the Ret/Gdnf pathway is necessary for renal development and there is a temporal and spatial relationship(More)
Development of the fruit fly Drosophila depends in part on epigenetic regulation carried out by the concerted actions of the Polycomb and Trithorax group of proteins, many of which are associated with histone methyltransferase activity. Mouse PTIP is part of a histone H3K4 methyltransferase complex and contains six BRCT domains and a glutamine-rich region.(More)
Nephrin is expressed at the basolateral aspect of podocytes and is an important signaling protein at the glomerular slit diaphragm. In vitro studies have demonstrated that Nephrin phosphorylation-dependent signaling is able to assemble a protein complex that is able to polymerize actin. However, proximal signaling events that result in nephrin tyrosine(More)
