	three Krüppel related zinc fingers at the C terminus

HOMOLOGY

interspecies

homolog to murine Klf3

Homologene

FAMILY	CACCC binding zinc finger family

SUBCELLULAR LOCALIZATION	intracellular
	intracellular,nucleus,chromatin/chromosome

basic FUNCTION	transcriptional corepressor with CTBP1 involved in hematopoiesis
	transcriptional regulator of muscle genes, which may play an important role in muscle differentiation

text	hematopoietic differentiation

PATHWAY

metabolism

a component

INTERACTION

DNA	binding CACCC box containing proteins

RNA

small molecule

protein	CTBP1 acting with KLF3 as a repressor for a number of transcription factors
	associate with CTBP2 and FHL3, which mediate its repressive effects on gene transcription
	binds the CEBPA promoter and both are implicated in controlling adipogenesis
	represses the Klf8 (Krüppel-like Factor 8) gene
	interacting with SRF (physically associate and synergize in transactivating the CKM (Muscle creatine kinase) promoter independently of SRF binding to CArG motifs
