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.

Identification of a Gialpha binding site on type V adenylyl cyclase.

Dessauer CW, Tesmer JJ, Sprang SR, Gilman AG

The stimulatory G protein alpha subunit Gsalpha binds within a cleft in adenylyl cyclase formed by the alpha1-alpha2 and alpha3-beta4 loops of the C2 domain. The pseudosymmetry of the C1 and C2 domains of adenylyl cyclase suggests that the homologous inhibitory alpha subunit Gialpha could bind to the analogous cleft within C1. We demonstrate that myristoylated guanosine 5'-3-O-(thio)triphosphate-Gialpha1 forms a ... [more]
