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.

Placing the HIRA histone chaperone complex in the chromatin landscape.

Pchelintsev NA, McBryan T, Rai TS, van Tuyn J, Ray-Gallet D, Almouzni G, Adams PD

The HIRA chaperone complex, comprised of HIRA, UBN1, and CABIN1, collaborates with histone-binding protein ASF1a to incorporate histone variant H3.3 into chromatin in a DNA replication-independent manner. To better understand HIRA's function and mechanism, we integrated HIRA, UBN1, ASF1a, and histone H3.3 chromatin immunoprecipitation sequencing and gene expression analyses. Most HIRA-binding sites colocalize with UBN1, ASF1a, and H3.3 at active ... [more]
