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.

The ubiquitin-specific protease USP15 promotes RIG-I-mediated antiviral signaling by deubiquitylating TRIM25.

Pauli EK, Chan YK, Davis ME, Gableske S, Wang MK, Feister KF, Gack MU

Ubiquitylation is an important mechanism for regulating innate immune responses to viral infections. Attachment of lysine 63 (Lys(63))-linked ubiquitin chains to the RNA sensor retinoic acid-inducible gene-I (RIG-I) by the ubiquitin E3 ligase tripartite motif protein 25 (TRIM25) leads to the activation of RIG-I and stimulates production of the antiviral cytokines interferon-α (IFN-α) and IFN-β. Conversely, Lys(48)-linked ubiquitylation of TRIM25 ... [more]
