Neuron 98, 977–91. Excitatory and Inhibitory Neurons Utilize Different Ca2+ Sensors and Sources to Regulate Spontaneous Release. 2018

Courtney, N.A., Briguglio, J.S., Bradberry, M.M., Greer, C., Chapman, E.R.

Notes: To localize and see Doc2 in live neurons the authors generated C-terminal HaloTag® fusion proteins of Doc2 isoforms, then conjugated these fusions with JF646 HaloTag® Ligand dye. In other studies a HaloTag ® Pull-Down System to study t-SNARE binding activities on the syt1 and Doc2β constructs. (5095)

Cancer Sci. 109(2), 373–83. PRDM14 directly interacts with heat shock proteins HSP90α and glucose-regulated protein 78. 2017

Moriya, C., Taniguchi, H., Nagatoishi, S., Igarashi, H., Tsumoto, K. and Imai, K.

Notes: PRDM14 is dysregulated in a variety of cancers, including breast and pancreatic cancer, and overexpression leads to stem-cell-like phenotypes associated with aggressive tumors. Here, PRDM14 interacting proteins are identified using the HaloTag® Mammalian Pull-down System. The interactions of PRDM14 and glucoseregulated protein 78 (GRP78) and heat shock protein 90-a (HSP90a) were validated in vivo with the NanoBRET™ assay. (5053)

Cell Rep. 16, 37–47. The TIP60 complex is a conserved coactivator of HIF1A. 2016

Perez-Perri, J.I., Dengler, V.L., Audetat, K.A., Pandey, A., Bonner, E.A., Urh, M., Mendez, J., Daniels, D.L., Wappner, P., Galbraith M.D. and Espinosa, J.M.

Notes: HaloTag® Pull-Down Assay
HEK293T (12 × 106 cells) were plated and grown to 70–80% confluence (approximately 18 hours). The cells were then transfected (using FuGENE® HD Transfection Reagent [Cat.# E2311]) with either 30µg of HaloTag(HT)-HIF1A or HT-alone control vector (vectors available by custom order from Promega Custom Assay Services). Clarified lysates from both HT-HIF1A and HT-alone control cells were prepared and incubated with HaloLink™ Resin (HaloTag® Mammalian Pull-Down System [Cat.# G6500, G6504]). Proteins were digested with trypsin, and digestion was quenched with formic acid. Digested peptides were analyzed by mass spectrometry.

NanoBRET™ Assay
HCT116 and HEK293 cells (8 ×105) were plated in each well of a 6-well plate and co-transfected with one of three acceptors: HT-Pontin, HT-Reptin or HT-TIP60, in combination with the HIF1A-NanoLuc(NL) donor. The following NanoBRET pairs used are available by custom order from Promega Custom Assay Services: HIF1α-NLuc + HT-TIP60, HIF1α-NLuc + HT-Pontin or HIF1α-NLuc + HT-Reptin. (4718)

Cell 153, 1327-1339. HIF1A Employs CDK8-Mediator to Stimulate RNAPII Elongation in Response to Hypoxia. 2013

Galbraith, M., Allen, M., Bensard, C., Wang, X., Schwinn, M., Qin, B., Long, H., Daniels, D., Hahn, W., Dowell, R., and Espinosa, J.

Notes: These authors identified a previously unknown interaction between the transcription factor HIF1A and the cyclin-dependent kinase CDK8 (a component of the Mediator complex) in the regulation of genes associated with cellular survival under low-oxygen conditions. As part of the study, HaloTag technology was used to identify proteins interacting with CDK8 in a colorectal cancer cell line. Specifically, cells were transfected with CDK8 and CDK19 HaloTag fusion constructs obtained from Kazusa Institute. The cell lysates were then used in pulldown assays to capture interacting proteins. The results showed that CDK8 and CDK19 are present in mutually exclusive Mediator complexes. Details of the transfection are as follows: HCT116 cells were plated in 150 mm dishes and grown to 70%–80% confluence before transfection with 30 μg of plasmid DNA using FuGENE HD Transfection Reagent.

Current Chemical Genomics 6, 72-78. HaloTag, a Platform Technology for Protein Analysis. 2012

Urh, M., and Rosenberg, M.

Notes: This paper provides an overview of the many applications of HaloTag® Technology. The authors describe the development of the technology, focusing on it's multifunctional utility for protein imaging, protein isolation and display, and in the study of protein complexes and interactions. They also discuss it's potential to facilitate proteomics research studies across complex biological systems at the biochemical, cell-based and whole animal level. (4325)
