Product Overview
This rabbit polyclonal antibody detects fez family zinc finger protein 1 (gene FEZF1) in human, mouse and rat samples and is validated for Western blot, ICC/IF, flow cytometry and ELISA. The predicted molecular weight is 52.0 kDa, and the supplier reports an observed band at about 65 kDa.
FEZF1 is a zinc finger transcriptional repressor active in the developing nervous system. It is needed for olfactory sensory neurons to project and terminate their axons correctly and contributes to patterning of the forebrain. FEZF1 mutations are linked to Kallmann syndrome, and the protein is studied in neurodevelopment.
