RNA-binding protein with binding specificity for poly(C). May play an important role in neural development. Predominantly cytoplasmic. May shuttle between cytoplasm and nucleus. Expressed predominantly in fetal brain, in neurons but not glial cells. Mostly expressed in neuronal progenitor cells with reduced expression in differentiated cells. Less abundant in adult brain where expression is limited to cerebellum, olfactory bulb and hippocampus. Also found at lower levels in fetal and adult kidney, heart, lung and spleen. Expression is highest in fetal brain at E16 with decreased levels as development progresses. By postnatal day 3 detected in hippocampal pyrimidal neurons and cortical neurons.
