FLAG Tag Info

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.

Background

LSD1 belongs to the flavin monoamine oxidase family. It contains 1 SWIRM domain and is a component of a RCOR/GFI/LSD1/HDAC complex. LSD1 interacts directly with GFI1 and GFI1B. LSD1 speficially removes histone H3K4me2 to H3K4me1 or H3K4me0 through a FAD-dependent oxidative reaction. When forming a complex with androgen receptor (and possibly other nuclear hormone receptors), LSD1 changes its substrates to H3K9me2. Thus LSD1 is considered to act as a coactivator or a corepressor. It may play a role in the repression of neuronal genes. Alone, LSD1 is unable to demethylate H3 'Lys-4' on nucleosomes and requires the presence of RCOR1/CoREST to achieve such activity.
