FLAG-tag, or FLAG octapeptide, is a polypeptide protein tag that can be added to a protein using recombinant DNA technology. It can be used for affinity chromatography, then used to separate recombinant, overexpressed protein from wild-type protein expressed by the host organism. It can also be used in the isolation of protein complexes with multiple subunits.
A FLAG-tag can be used in many different assays that require recognition by an antibody. If there is no antibody against the studied protein, adding a FLAG-tag to this protein allows one to follow the protein with an antibody against the FLAG sequence. Examples are cellular localization studies by immunofluorescence or detection by SDS PAGE protein electrophoresis.
The peptide sequence of the FLAG-tag from the N-terminus to the C-terminus is: DYKDDDDK (1012 Da). It can be used in conjunction with other affinity tags, for example a polyhistidine tag (His-tag), HA-tag or Myc-tag. It can be fused to the C-terminus or the N-terminus of a protein. Some commercially available antibodies (e.g., M1/4E11) recognize the epitope only when it is present at the N-terminus. However, other available antibodies (e.g., M2) are position-insensitive.

Actopaxin, also known as alpha-parvin, belongs to the parvin family. It is widely expressed, with highest levels in heart, skeletal muscle, kidney and liver. Actopaxin contains 2 CH (calponin-homology) domains and probably plays a role in the regulation of cell adhesion and cytoskeleton organization. It interacts with integrin-linked protein kinase and probably with actin and the LD1 and LD4 motifs of PXN. Actopaxin binds directly to both F-actin and paxillin LD1 and LD4 motifs. Actopaxin also exhibits robust focal adhesion localization in several cultured cell types but is not found along the length of the associated actin-rich stress fibers. It is absent from actin-rich cell-cell adherens junctions.
