Affinity Capture-MS

An interaction is inferred when a bait protein is affinity captured from cell extracts by either polyclonal antibody or epitope tag and the associated interaction partner is identified by mass spectrometric methods.

Interacting partners of macrophage-secreted cathepsin B contribute to HIV-induced neuronal apoptosis.

Cantres-Rosario YM, Hernandez N, Negron K, Perez-Laspiur J, Leszyk J, Shaffer SA, Melendez LM

HIV-1 infection of macrophages increases cathepsin B secretion and induces neuronal apoptosis, but the molecular mechanism remains unclear.We identified macrophage-secreted cathepsin B protein interactions extracellularly and their contribution to neuronal death in vitro.Cathepsin B was immunoprecipitated from monocyte-derived macrophage supernatants after 12 days postinfection. The cathepsin B interactome was identified by label-free tandem mass spectrometry and compared with uninfected supernatants. ... [more]
