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.

Arsenate-mediated G2 cell cycle arrest in U-2OS cells involves phosphorylation of human polycomb protein 2 by p38 MAPK.

Wu W, Zhou H, He F, Xiao Z, Jiang Y, Zhao M

G2/M checkpoints ensure the proper timing of cell mitosis. We previously reported that p38 mitogen-activated protein kinase (MAPK) activation is essential for stress-induced G2 arrest in the U-2OS osteosarcoma cell line, but the molecular mechanism was obscure. Here, using the T7 phage display system, we find p38 directly binds to human polycomb protein 2 (HPC2), and arsenate-induced G2 arrest in ... [more]

Phenotypic Enhancement

A genetic interaction is inferred when mutation or overexpression of one gene results in enhancement of any phenotype (other than lethality/growth defect) associated with mutation or over expression of another gene.
