The POZ domain Krüppel-like zinc finger transcription repressor (POK family) contains many important molecules, including RP58, Bcl6 and PLZF. They function as transcription repressors via chromatin remodelling and histone deacetylation and are known to be involved in the development and tumourigenesis of various organs. Furthermore, they are important in the formation and function of the nervous system. This review summarizes the role of the POK family transcription repressors in the nervous system. We particularly targeted Rp58 (also known as Znf238, Znp238 and Zbtb18), a sequence-specific transcriptional repressor that is strongly expressed in developing glutamatergic projection neurons in the cerebral cortex. It regulates various physiological processes, including neuronal production, neuronal migration and neuronal maturation. Human studies suggest that reduced RP58 levels are involved in cognitive function impairment and brain tumour formation. This review particularly focuses on the mechanisms underlying RP58-mediated neuronal development and function. LINKED ARTICLES: This article is part of a themed issue on Neurochemistry in Japan.
