La ribonucleasa H (ARNasa H) es una endorribonucleasa que degrada específicamente la cadena de ARN de un híbrido de ARN-ADN para producir oligorribonucleótidos terminados en fosfato 5´ y ADN de una sola cadena.. Aplicaciones Extracción de ARNm durante la síntesis de ADNc de segunda cadena. Extracción de secuencias de poli(A) de ARNm en presencia de oligo(dT). Disociación dirigida por oligoribonucleótidos de ARN. Fuente Purificada a partir de E. coli que expresa el gen de ARNasa H de E. coli en un plásmido. Pruebas de rendimiento y calidad Ribonucleasa, endoexonucleasa inespecífica, endodesoxiribonucleasa 3´ y 5´. Definición de la unidad Una unidad hidroliza 1 nmol de ARN en poli(A)poli(dT) marcado como 3H en material soluble en ácido en 20 minutos a 37 °C. Condiciones de reacción de la unidad 20 mM de Tris-HCl (pH 7,5), 0,1 M de KCl, 10 mM de MgCl2, 0,1 mM de DTT, 5 % (peso/volumen) de sacarosa, 0,5 nmol de poli(A)poli(dT) marcado como 3H y enzima en 50 µl durante 20 min a 37 °C.

Abstract
Functions of Transforming Growth Factor-beta Family Type I Receptors and Smad Proteins in the Hypertrophic Maturation and Osteoblastic Differentiation of Chondrocytes.
'We investigated the effects of bone morphogenetic protein (BMP)-2, a member of the transforming growth factor-beta superfamily, on the regulation of the chondrocyte phenotype, and we identified signaling molecules involved in this regulation. BMP-2 triggers three concomitant responses in mouse primary chondrocytes and chondrocytic MC615 cells. First, BMP-2 stimulates expression ... More
De novo ceramide regulates the alternative splicing of caspase 9 and Bcl-x in A549 lung adenocarcinoma cells. Dependence on protein phosphatase-1.

Journal:J Biol Chem
PubMed ID:11801602
'In a recent study, we showed that ceramide induces the dephosphorylation of SR proteins, a family of protein factors that regulate alternative splicing. In this study, the regulation of the alternative processing of pre-mRNA of both caspase 9 and Bcl-x(L) was examined in response to ceramide. Treatment of A549 lung ... More
The novel WD-repeat protein MORG1 acts as a molecular scaffold for HIF prolyl-hydroxylase 3 (PHD3).
Authors:Hopfer U, Hopfer H, Jablonski K, Stahl RA, Wolf G,
Journal:J Biol Chem
PubMed ID:16407229
'Hypoxia-inducible factor-1 (HIF-1), a transcriptional complex composed of an oxygen-sensitive alpha- and a beta-subunit, plays a pivotal role in cellular adaptation to low oxygen availability. Under normoxia, the alpha-subunit of HIF-1 is hydroxylated by a family of prolyl hydroxylases (PHDs) and consequently targeted for proteasomal degradation. Three different prolyl hydroxylases ...

The application of resonance light scattering (RLS) particles for high-sensitivity detection of DNA hybridization on cDNA microarrays is demonstrated. Arrays composed of approximately 2000 human genes ( ... More
mRNA decay is rapidly induced after spore germination of Saccharomyces cerevisiae.
Spores from the yeast Saccharomyces cerevisiae can germinate and resume their vegetative growth when placed in favorable conditions. Biochemical studies on germination have been limited by the difficulty of obtaining a pure population of spores germinating synchronously. Here, we report that spores can be purified and sorted according to their ... More
