The protein of interest (bait) is fused to the reporter enzyme and expressed in cells. Here, BirA∗ was fused to normal Lamin A or the truncated form characteristic to this disease, called progerin (Chojnowski et al., 2015). All methods described until now give insight into chromatin interactions that can occur genome-wide without any spatial information. In fact, biotinylation relies on the number and accessibility of the targeted amino acid residues, mostly lysine or tyrosine. endobj endobj 9:1188. doi: 10.1038/s41467-018-03523-3522, Lobingier, B.

Furthermore, splitting the reporter enzyme results in smaller tags for the POI and therefore potentially less functional impact.

However, if the cell type or the enrichment strategy of the control differs significantly, it is always recommended to include an internal experimental control, rather than solely relying on the CRAPome database.
