Affinity Capture-Western

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 identified by Western blot with a specific polyclonal antibody or second epitope tag. This category is also used if an interacting protein is visualized directly by dye stain or radioactivity. Note that this differs from any co-purification experiment involving affinity capture in that the co-purification experiment involves at least one extra purification step to get rid of potential contaminating proteins.

A positive role of mammalian Tip41-like protein, TIPRL, in the amino-acid dependent mTORC1-signaling pathway through interaction with PP2A.

Target of rapamycin complex 1 (TORC1) has a key role in cellular regulations in response to environmental conditions. In yeast, Tip41 downregulates TORC1 signaling via activation of PP2A phosphatase. We show here that overexpression of TIPRL, a mammalian Tip41, suppressed dephosphorylation of mechanistic TORC1 (mTORC1) substrates under amino acid withdrawal, and knockdown of TIPRL conversely attenuated phosphorylation of those substrates ...
