  • FunctionProbable transcription factor which exert its primary action widely during early neural development and in a very limited set of neurons in the mature brain.
  • Tissue specificityBrain specific.
  • Involvement in diseaseDefects in POU3F4 are a cause of deafness X-linked type 2 (DFNX2) [MIM:304400]. A mixed type of deafness characterized by both conductive hearing loss resulting from stapes (perilymphatic gusher) fixation and progressive sensorineural deafness.
  • Sequence similaritiesBelongs to the POU transcription factor family. Class-3 subfamily.
    Contains 1 homeobox DNA-binding domain.
    Contains 1 POU-specific domain.

  • IHC image of BRN4 staining in Rat normal brain formalin fixed paraffin embedded tissue section, performed on a Leica BondTM system using the standard protocol F. The section was pre-treated using heat mediated antigen retrieval with sodium citrate buffer (pH6, epitope retrieval solution 1) for 20 mins. The section was then incubated with ab104562, 5µg/ml, for 15 mins at room temperature and detected using an HRP conjugated compact polymer system. DAB was used as the chromogen. The section was then counterstained with haematoxylin and mounted with DPX.

    For other IHC staining systems (automated and non-automated) customers should optimize variable parameters such as antigen retrieval conditions, primary antibody concentration and antibody incubation times.
