Anal. Biochem. 392, 45-53. Protein-protein interaction studies on protein arrays: effect of detection strategies on signal-to-background ratios. 2009

Hurst, R., Hook, B., Slater, M.R., Hatrnett, J., Storts, D.R., and Nath, N.

Notes: These authors compared 6 different detection strategies for protein-protein interactions on protein arrays. They expressed HaloTag® labeled bait proteins in a cell-free expression system, and captured these bait proteins onto coated glass slides using the HaloLink™ Array System. They then compared detection strategies using prey proteins labeled as follows: 1)35S methionine, 2) fluorescence (BODIPY-FL) and 3) biotin labeling of lysine residues using modified Lys tRNA, 4) chemical labeling after expression, 5) HaloTag® fusion, and 6) N-terminal FLAG tag. The authors evaluated signal:background ratios, adaptability to high-throughput screening, and ease of use. (3999)

J. Gen. Virol. 87, 3679-3686. Characterization of the 5' internal ribosome entry site of Plautia stali intestine virus. 2008

Shibuya, N., and Nakashima, N.

Notes: The Plautia stali virus contains two open reading frames and includes a 5´ internal ribosome entry site (IRES) and an intergenic IRES region. These authors showed that the 5´ IRES was functional and initiated translation in insect cell lysate, but not in rabbit reticulocyte lysate or wheat germ extract. The efficiency of translation mediated by the 5´ IRES region was tested with and without cap analogue using various firefly and Renilla luciferase reporter constructs. They also used deletion mutants to identify the specific regions required for translation initiation. (3942)

J. Virol. 80, 6669-6677. Human papillomavirus e7 oncoprotein dysregulates steroid receptor coactivator 1 localization and function.
2006

Baldwin, A., Huh, K-W. and Mϋnger, K.

Notes: The MagneGST™ Protein Purification System was used to purify GST fusion proteins of the oncoprotein HPV16 E7 or various mutants of HPV16 E7. The purified GST fusion proteins were used for in vitro binding experiments with steroid receptor coactivator 1 (SRC-1), which was produced using the TNT® T7 Coupled Wheat Germ Extract System and labeled with the Transcend™ Non-Radioactive Translation Detection System. GST pull-down assays were resolved by Western analysis using streptavidn-horseradish peroxidase and alpha-GST. To determine the effects of endogenously expressed HPV16 E7 on SCR-1-mediated transcription, luciferase reporters under the control of either the IL-8 promoter or an artificial promoter containing three estrogen response elements repeats (3 × EREs) were cotransfected with a Renilla control vector into two human cervical cancer lines (C33A and CaSki) using either the Transfast™ Transfection Reagent or another commercial transfection reagent. The Dual-Luciferase® Reporter Assay was then used to determine luciferase activity to functionally map the E7-interacting domain and to determine the effects of high- and low-risk PHV E7s on SRC-1-mediated transcription.

Zheng Q., Yin G., Yan C., Cavet M. and Berk B.C.

Notes: The authors performed a yeast two-hybrid screen using big mitogen-activated kinase 1 (BMK1/ERK5) as the bait and identified the scaffolding protein 14-3-3beta. To confirm this interaction, the cloned mouse BMK1 gene was expressed in the TNT® T7 Quick Coupled Transcription/Translation System. The expressed protein was labeled with Transcend™ tRNA.  Using a GST-14-3-3beta fusion protein, a pull-down assay was performed and the direct binding confirmed after immunoblotting and staining with streptavidin-horseradish peroxidase (HRP).  The interaction of various BMK1 mutants were tested in a mammalian two-hybrid system and measured by the Dual-Luciferase® Reporter Assay System.

2002

Weinhofer, I., Forss-Petter, S., Zigman, M. and Berger, J.

Notes: The sterol regulatory element-binding protein-1a (SREBP1a) was in vitro transcribed and translated from a plasmid template using TNT® T7 Quick for PCR DNA. A control reaction was performed using Transcend™ tRNA to confirm that the 120KDa protein was expressed correctly.  Unlabeled SREBP1a was used in gel-shift assays with a labeled oligo representing the SRE motif from the human ABCD2 gene promoter.  (3222)

Chien, W. , and Pei, L.

Notes: The TNT® T3 Coupled Reticulocyte Lysate System was used to express the PTTG-binding factor, a 179 amino acid protein (predicted 19.7kDa). The protein was translated in the presence of the Transcend™ Biotinylated tRNA. The expressed protein was used to GST-fusion protein pulldown reactions with a PTTG-GST fusion. The bound proteins were removed by boiling in SDS sample buffer, electrophoresed, transferred, and detected by chemiluminescent HRP. (0032)

A protein, JAM, was expressed as a GST fusion in E. coli and immobilized to a glutathione-linked sepharose beads or peptides were immobilized to sepharose beads. The translation extract was interacted with the beads, washed and bound protein removed by boiling in SDS sample buffer. The bound protein was electrophoresed, transferred and detected via the biotin tag on the ZO-1 protein. (0031)

Morgan, H. , Smith, M. , Burke, Z. , and Carter, D.

Notes: A clone of the rat AF-9 cDNA was isolated. Two potential start codons were present in the cDNA. To see which is preferred by a mammalian translation system, the cDNA was translated in vitro with the TNT® Coupled Reticulocyte Lysate System and the Transcend™ Biotinylated tRNA. The preferred transcript was the first ATG resulting in the 370 amino acid (40.7kDa predicted molecular weight) which had 47 lysines. (0033)
