Also known as: cb125; sb:cb125; zgc:91780
Summary: Predicted to enable DNA-binding transcription factor activity, RNA polymerase II-specific and RNA polymerase II cis-regulatory region sequence-specific DNA binding activity. Acts upstream of or within negative regulation of mesodermal cell fate specification; regulation of ectodermal cell fate specification; and ventricular compact myocardium morphogenesis. Is expressed in several structures, including EVL; cardiovascular system; ectoderm; pectoral fin; and presumptive ectoderm. Orthologous to human KLF2 (KLF transcription factor 2).

What's a GeneRIF?

These studies provide new insights into how Klf2 regulates cardiovascular development and specifically myocardial wall integrity.
Title: The flow responsive transcription factor Klf2 is required for myocardial wall integrity by modulating Fgf signaling.
reveals a beta1 integrin-Klf2-Egfl7-signaling pathway that is tightly regulated by cerebral cavernous malformation proteins

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
