An interaction is inferred when a bait-enzyme fusion protein selectively modifies a vicinal protein with a diffusible reactive product, followed by affinity capture of the modified protein and identification by mass spectrometric methods.

Differentiation-dependent proximity proteomics identifies novel host factors linked to HPV16 E2 function.

James CD, Youssef A, Prabhakar AT, Roe JD, Lu E, Witt A, Giri S, Bristol ML, Bridy P, Wang X, Rijal A, Lyons C, Morgan IM

Human papillomavirus 16 (HPV16) is a causative agent of oropharyngeal, cervical, and anogenital cancers. The viral E2 protein is essential for viral genome replication, transcriptional regulation, episome maintenance, and activation of the host DNA damage response. Despite its central role, the full network of HPV16 E2 interactions with host proteins remains incompletely defined, particularly under differentiating conditions, which support the ... [more]
