Application

Spautin-1 has been used as an autophagy inhibitor:
  • to study its effects on vascular, glial, and neuronal alterations in the oxygen-induced retinopathy mouse model
  • to evaluate its pre-treatment effect on the response of canine osteosarcoma cells to doxorubicin
  • to study its effects on the production of interleukin (IL)-6 by oxidatively stressed dendritic cells (OS-DCs) in Luminex assay

Biochem/physiol Actions

Spautin-1 inhibits the activity of two ubiquitin-specific peptidases, USP10 and USP13, causing an increase in proteasomal degradation of class III PI3 kinase complexes, which have been shown to regulate autophagy.
Specific and potent autophagy inhibitor-1 (Spautin-1) is a small molecule, which can inhibit autophagy and induce cancer cell death. It inhibits autophagy by degrading beclin-1. Spautin-1 augments the efficiency of radiation therapy and chemotherapy in various human cancer cell lines.

Screening assays performed against membrane protein targets (e.g. phage display) are hampered by issues arising from protein expression and purification, protein stability in detergent solutions and epitope concealment by detergent micelles. Here, we have studied a fast and simple method

We describe an original activity assay for membrane transport that uses the proton motive force-dependent efflux pump MexAB from Pseudomonas aeruginosa. This pump is co-reconstituted into proteoliposomes together with bacteriorhodopsin (BR), a light-activated proton pump. In this system, upon illumination

Neosartorya fumigata (Aspergillus fumigatus) is the most common cause of invasive aspergillosis, a frequently fatal lung disease primarily affecting immunocompromised individuals. This opportunistic fungal pathogen produces several classes of specialised metabolites including products of a branch of the ergot alkaloid
