Pulldown of Maspin-GST in Human Cells Treated or Untreated with Nocodazole


ABSTRACT: Human cells, either asynchronous or synchronized with nocodazole, were subjected to a pulldown assay using GST-maspin. Interacting proteins were eluted using 10 mM reduced glutathione, 150 mM NaCl, 1 mM DTT, and 50 mM Tris-HCl (pH 8.5).

Maspin/SerpinB5 is an abundant and pleiotropic protein mostly expressed by epithelia. Initially described as a tumor suppressor, it has been reported as a regulator of cell adhesion, migration, and invasion. How intracellular Maspin orchestrates these processes is poorly understood. In this study, we utilized Affinity purification-Mass spectrometry (AP/MS) alongside in vitro reconstitution assays to establish that Maspin directly interacts with microtubules and microfilaments. Additionally, CRIS  ...[more]
