... and normal embryonic movement were restored, confirming that loss of prdm14 expression accounts for the observed defects. Mechanistically, Prdm14 protein binds to the promoter region of islet2 , a known transcription factor required for CaP development. Notably, disruption of islet2 function caused similar...

... of axons of sensory neurons. The reason why different neurons respond to Slit in different ways is largely unknown. Islet2 is a LIM/homeodomain-type transcription factor that specifically regulates elongation and branching of the peripheral axons of the primary sensory neurons in zebrafish embryos. We...

... segments by 15 hours. Thus, islet1 expression could prevent a cell from adopting the CaP fate. MiP becomes committed by about 17-18 hours, which follows the onset of islet1 and lim3 expression in trunk segments. The expression of particular combinations of islet1, islet2 and lim3 in primary...
