May be involved in retinal development. Component of the DREAM complex. Expressed in the brain, liver and retina. Highly expressed in the retinal ganglion cell and inner nuclear layers at the parr stage. Expressed at a lower level in inner segments of some retinal photoreceptors. Down-regulated in the retina at smoltification, the metamorphic transformation from a parr to a molt. Belongs to the lin-52 family.
