GZF1 Antibody: The GDNF-inducible zinc finger protein 1 (GZF1) is a sequence-specific transcriptional repressor with a BTB/POZ domain and ten zinc finger motifs whose expression is required for renal branching morphogenesis during kidney development. GZF1 binds to the 5'regulatory region of the homeodomain protein HOXA10, suggesting that GZF1 may play a role in morphogenesis other than kidney development. Recent experiments have indicated that GZF1 associates with nucleolin and this association is mediated by the first four zinc finger motifs of GZF1. It is thought that Nucleolin modulates the subcellular localization of GZF1 as well as its transcriptional repressor activity.
