Kruppel-like factor 13 (KLF13) belongs to a family of transcription factors that contain three classical zinc finger DNA binding domains consisting of a zinc atom tetrahedrally coordinated by two cysteines and two histidines (C2H2 motif). These transcription factors bind to GC rich sequences and related GT and CACCC boxes. KLF13 appears to be an important component of the transcription network required for heart development and cholesterol homeostasis.
