Co-fractionation

Interaction inferred from the presence of two or more protein subunits in a partially purified protein preparation. If co-fractionation is demonstrated between 3 or more proteins, then add them as a complex.

Purification and characterization of 26S proteasomes from human and mouse spermatozoa.

Tipler CP, Hutchon SP, Hendil K, Tanaka K, Fishel S, Mayer RJ

We purified by fractionation on 10-40% glycerol gradients, 26S proteasomes from normal human spermatozoa. These proteasomes, which participate in the ATP-dependent degradation of ubiquitinated proteins, share a similar sedimentation coefficient to those purified from other human tissues. Fluorogenic peptide assays reveal they have chymotrypsin, trypsin and peptidyl-glutamyl-like peptide hydrolysing activities; the chymotrypsin activity is ablated by the specific 26S proteasome ...
