Project description:Gene profiling studies using RNA from cells overexpressing point mutants of SATB1 defective in phosphorylation or acetylation unequivocally demonstrated the importance of these modifications towards the ability of SATB1 to act as a global regulator of gene expression in Jurkat T cells. Jurkat cells express SATB1 endogenously, and therefore we monitored the effect of overexpression of SATB1. Under this situation, the overexpressed mutants will compete with the endogenously expressed wild type SATB1 and therefore the effect on gene expression may differ from SATB1 non-expressing non T cell line such as HeLa.

Project description:Kynureninase is a member of a large family of catalytically diverse but structurally homologous pyridoxal 5'-phosphate (PLP) dependent enzymes known as the aspartate aminotransferase superfamily or alpha-family. The Homo sapiens and other eukaryotic constitutive kynureninases preferentially catalyze the hydrolytic cleavage of 3-hydroxy-l-kynurenine to produce 3-hydroxyanthranilate and l-alanine, while l-kynurenine is the substrate of many prokaryotic inducible kynureninases. The human enzyme was cloned with an N-terminal hexahistidine tag, expressed, and purified from a bacterial expression system using Ni metal ion affinity chromatography. Kinetic characterization of the recombinant enzyme reveals classic Michaelis-Menten behavior, with a Km of 28.3 +/- 1.9 microM and a specific activity of 1.75 micromol min-1 mg-1 for 3-hydroxy-dl-kynurenine. Crystals of recombinant kynureninase that diffracted to 2.0 A were obtained, and the atomic structure of the PLP-bound holoenzyme was determined by molecular replacement using the Pseudomonas fluorescens kynureninase structure (PDB entry 1qz9) as the phasing model. A structural superposition with the P. fluorescens kynureninase revealed that these two structures resemble the "open" and "closed" conformations of aspartate aminotransferase. The comparison illustrates the dynamic nature of these proteins' small domains and reveals a role for Arg-434 similar to its role in other AAT alpha-family members. Docking of 3-hydroxy-l-kynurenine into the human kynureninase active site suggests that Asn-333 and His-102 are involved in substrate binding and molecular discrimination between inducible and constitutive kynureninase substrates.

Project description:SATB1 is a genetic master regulator in dopaminergic neurons. We try to identify the downstream regulated genes and pathways of SATB1 in human dopaminergic and CTX neurons. The RNA-Seq experiment was performed to investigate the role of the genetic master regulator SATB1 in human dopaminergic neurons in comparison to cortical neurons. We generated a human embryonic stem cell knockout clone for SATB1 and differentiated this clone into either dopaminergic or cortical neurons. Immature dopaminergic (day 30 of differentiation), mature dopaminergic (day 50 of differentiation) and mature cortical neurons (day 30 of differentiation) were subsequently subjected to RNA-Seq. We compared wild type and SATB1-KO neurons at the afore mentioned time points, to characterize the regulatory role of SATB1 in the different neuron subtypes.
