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.

Characterization of a nuclear 20S complex containing the survival of motor neurons (SMN) protein and a specific subset of spliceosomal Sm proteins.
Spinal muscular atrophy (SMA) is a neurodegenerative disease of motor neurons caused by reduced levels of functional survival of motor neurons (SMN) protein. Cytoplasmic SMN directly interacts with spliceosomal Sm proteins and facilitates their assembly onto U snRNAs. Nuclear SMN, in contrast, mediates recycling of pre-mRNA splicing factors. In this study, we have addressed the function of SMN in the ... [more]

| SMN1 SNRPD2 | Co-fractionation 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. | Low | - | BioGRID | - | |
| SMN1 SNRPD2 | Reconstituted Complex Reconstituted Complex An interaction is inferred between proteins in vitro. This can include proteins in recombinant form or proteins isolated directly from cells with recombinant or purified bait. For example, GST pull-down assays where a GST-tagged protein is first isolated and then used to fish interactors from cell lysates are considered reconstituted complexes (e.g. PUBMED: 14657240, Fig. 4A or PUBMED: 14761940, Fig. 5). This can also include gel-shifts, surface plasmon resonance, isothermal titration calorimetry (ITC) and bio-layer interferometry (BLI) experiments. The bait-hit directionality may not be clear for 2 interacting proteins. In these cases the directionality is up to the discretion of the curator. | Low | - | BioGRID | - |
