Co-purification

An interaction is inferred from the identification of two or more protein subunits in a purified protein complex, as obtained by classical biochemical fractionation or affinity purification and one or more additional fractionation steps.

The linker histone H1 generally participates in the establishment of chromatin structure. However, of the seven somatic H1 isotypes in humans some are also implicated in the regulation of local gene expression. Histone H1 isotype 4 (H1.4) represses transcription, and its lysine residue 26 (Lys(26)) was found to be important in this aspect. H1.4K26 is known to be methylated and ... [more]

Co-crystal Structure

Interaction directly demonstrated at the atomic level by X-ray crystallography. Also used for NMR or Electron Microscopy (EM) structures. If there is no obvious bait-hit directionality to the interaction involving 3 or more proteins, then the co-crystallized proteins should be listed as a complex.
