 For instance, MEC-8 and UNC-75 containing RRM domains localize to regions of hypodermis and nervous system, respectively.Furthermore, another RRM-containing RBP, EXC-7, is revealed to localize in embryonic excretory canal cells and throughout the nervous system during somatic development.ZBP1 was shown to regulate dendritogenesis (dendrite formation) in hippocampal neurons.
