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.
Heart valves originate from progenitors located in the ventricle and atrium that generate the valve leaflets through a coordinated set of endocardial tissue movements, dependent on the expression of fibronectin1b. Blood flow and klf2a control these cell behaviours and fibronectin1b synthesis.
Title: klf2a couples mechanotransduction and zebrafish valve morphogenesis through fibronectin synthesis.
In turn, Heg1 stabilizes levels of Krit1 protein, and both Heg1 and Krit1 dampen expression levels of klf2a, a major mechanosensitive gene. The correct balance of blood-flow-dependent induction and Krit1 protein-mediated repression of klf2a and notch1b ultimately shapes cardiac valve leaflet morphology.

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.
