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.

Deficiency of Rbbp1/Arid4a and Rbbp1l1/Arid4b alters epigenetic modifications and suppresses an imprinting defect in the PWS/AS domain.

Wu MY, Tsai TF, Beaudet AL

Prader-Willi syndrome (PWS) and Angelman syndrome (AS) are caused by deficiency of imprinted gene expression from paternal or maternal chromosome 15q11-q13, respectively. Genomic imprinting of the PWS/AS domain is regulated through a bipartite cis-acting imprinting center (PWS-IC/AS-IC) within and upstream of the SNRPN promoter. Here, we show that two Rb-binding protein-related genes, Rbbp1/Arid4a and Rbbp1l1/Arid4b, are involved in the regulation ... [more]

Mutations/deletions in separate genes, each of which alone causes a minimal phenotype, but when combined in the same cell results in a more severe fitness defect or lethality under a given condition. This term is reserved for high or low throughput studies with scores.
