Core Tip

Core tip: To investigate the functional role of IKBKAP in enteric nervous system (ENS) development, we knocked down the zebrafish ortholog ikbkap using a translation blocking antisense morpholino. Loss of ikbkap caused aganglionosis and a reduced number of enteric neurons, indicating that IKBKAP is important for proper ENS development.
