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.

Guanine nucleotide dissociation inhibitor activity of the triple GoLoco motif protein G18: alanine-to-aspartate mutation restores function to an inactive second GoLoco motif.

Kimple RJ, Willard FS, Hains MD, Jones MB, Nweke GK, Siderovski DP

GoLoco ('Galpha(i/o)-Loco' interaction) motif proteins have recently been identified as novel GDIs (guanine nucleotide dissociation inhibitors) for heterotrimeric G-protein alpha subunits. G18 is a member of the mammalian GoLoco-motif gene family and was uncovered by analyses of human and mouse genomes for anonymous open-reading frames. The encoded G18 polypeptide is predicted to contain three 19-amino-acid GoLoco motifs, which have been ... [more]
