PLAGL1 is a C2H2 zinc finger protein with transactivation and DNA-binding activity. This gene has been shown to exhibit antiproliferative activities and is a tumor suppressor gene candidate.This gene encodes a C2H2 zinc finger protein with transactivation and DNA-binding activity. This gene has been shown to exhibit antiproliferative activities and is a tumor suppressor gene candidate. Two transcript variants encoding different isoforms have been found for this gene.This gene encodes a C2H2 zinc finger protein with transactivation and DNA-binding activity. This gene has been shown to exhibit antiproliferative activities and is a tumor suppressor gene candidate. Many transcript variants encoding two different isoforms have been found for this gene.
