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.

Human mitochondrial transcription factor B1 interacts with the C-terminal activation region of h-mtTFA and stimulates transcription independently of its RNA methyltransferase activity.

McCulloch V, Shadel GS

A significant advancement in understanding mitochondrial gene expression is the recent identification of two new human mitochondrial transcription factors, h-mtTFB1 and h-mtTFB2. Both proteins stimulate transcription in collaboration with the high-mobility group box transcription factor, h-mtTFA, and are homologous to rRNA methyltransferases. In fact, the dual-function nature of h-mtTFB1 was recently demonstrated by its ability to methylate a conserved rRNA ... [more]
