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.

Inactivation of CREB mediated gene transcription by HDAC8 bound protein phosphatase.

Gao J, Siddoway B, Huang Q, Xia H

CREB activation via phosphorylation at serine 133 and resulting CREB mediated gene expression is a critical event which can have a significant effect on many cellular processes, including cell survival and plasticity. CREB can be activated by many kinases, for example, it can be phosphorylated by PKA, MAPK, and CaMKIV. The various signaling pathways leading to CREB activation have been ... [more]
