Gene Ontology Molecular Function
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.
Publication
Nucleotide binding by TAP mediates association with peptide and release of assembled MHC class I molecules.
Newly synthesised peptide-receptive major histocompatibility complex (MHC) class I molecules form a transient loading complex in the endoplasmic reticulum with the transporter associated with antigen processing (TAP) and a set of accessory proteins. Binding of peptide to the MHC class I molecule is necessary for dissociation of the MHC class I molecule from the complex with TAP, but other components ... [more]
