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.

Ribosomal protein L6 (RPL6) is recruited to DNA damage sites in a poly(ADP-ribose) polymerase-dependent manner and regulates the DNA damage response.

Ribosomal proteins are the building blocks of ribosome biogenesis. Beyond their known participation in ribosome assembly, the ribosome-independent functions of ribosomal proteins are largely unknown. Here, using immunoprecipitation, subcellular fractionation, His-ubiquitin pulldown, and immunofluorescence microscopy assays, along with siRNA-based knockdown approaches, we demonstrate that ribosomal protein L6 (RPL6) directly interacts with histone H2A and is involved in the DNA damage ...
