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.

A mechanism for translationally coupled mRNA turnover: interaction between the poly(A) tail and a c-fos RNA coding determinant via a protein complex.

Grosset C, Chen CY, Xu N, Sonenberg N, Jacquemin-Sablon H, Shyu AB

mRNA turnover mediated by the major protein-coding-region determinant of instability (mCRD) of the c-fos proto-oncogene transcript illustrates a functional interplay between mRNA turnover and translation. We show that the function of mCRD depends on its distance from the poly(A) tail. Five mCRD-associated proteins were identified: Unr, a purine-rich RNA binding protein; PABP, a poly(A) binding protein; PAIP-1, a poly(A) binding ... [more]

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.
