ZBTB18 (C2H2-171) encodes a protein with an N-terminal POZ/BTB domain and four C-terminal C2H2 zinc finger domains, is preferentially expressed in brain neurons (highest in cerebellum), and maps to human chromosome 1q44-ter. |

ZNF238/ZBTB18 is highly expressed in postmitotic cerebellar granule neurons and differentiated neurons; knockdown in mouse granule neuron precursors (GNPs) decreases MAP2, NeuN, and p27 expression, while re-introduction in medulloblastoma and glioblastoma cells decreases cyclin D1, increases MAP2 and p27, reduces proliferation, and promotes cell death, demonstrating an antiproliferative/pro-differentiation function in neural cells. |

RP58/ZBTB18 acts as a transcriptional repressor of proneurogenic genes pax6, ngn2, and neuroD1 (ngn2 and neuroD1 being direct targets), and its CNS-specific conditional knockout causes microencephaly, corpus callosum agenesis, cerebellar hypoplasia, reduced neuronal differentiation, and increased glial differentiation, demonstrating a required role in neuronal differentiation and brain expansion. |

ZBTB18 is silenced in the mesenchymal subtype of glioblastoma through aberrant promoter methylation; loss of ZBTB18 contributes to aggressive GBM phenotype, and restitution of ZBTB18 expression reverses this phenotype and impairs tumor-forming ability, establishing ZBTB18 as a tumor suppressor regulated epigenetically. |

Disease-associated missense mutations in ZBTB18 (N461S, R495G, and others) that map to DNA-contact residues within the zinc-finger domain alter DNA-binding specificity and transcriptional regulatory activity in vitro, and impair radial migration of newborn neurons in vivo, linking specific zinc-finger residues to DNA contact and neuronal migration. |

ZBTB18 interacts with co-activator/co-repressor CTBP1/2 and LSD1 at SREBP gene promoters; ZBTB18 binding is associated with reduced LSD1 demethylase activity (H3K4me2 and H3K9me2) and promotes LSD1 scaffolding with ZNF217, thereby inhibiting SREBP-dependent lipid synthesis in glioblastoma. |

In glioblastoma, calpain protease cleaves ZBTB18, generating an N-terminal fragment that localizes to the cytoplasm (unable to repress transcription); this cytoplasmic N-terminal fragment interacts with CTBP1/2 and activates HIF1A-regulated genes, leading to increased lipid uptake, lipid droplet accumulation, and enhanced metabolic activity. |

ZBTB18 acts as a transcriptional repressor that reduces chromatin accessibility at promoters of metastasis-driving genes (e.g., Tgfbr2), preventing TGFβ1 pathway activation, reducing cell migration and invasion, and inducing widespread chromatin closing; loss of ZBTB18 activity defines metastasis-competent cancer cells. |
