POGZ binds HP1α through a zinc-finger-like motif (distinct from the canonical PxVxL motif used by other HP1-binding proteins), competing with PxVxL proteins and destabilizing the HP1α-chromatin interaction. POGZ depletion impairs normal mitotic progression, HP1α dissociation from mitotic chromosome arms, and correct Aurora B kinase activation and dissociation from chromosome arms during M phase. |

POGZ interacts with LEDGF/p75 through its transposase-derived DDE domain; the DDE domain of POGZ overlaps with the binding site used by HIV-1 integrase on LEDGF/p75, and HIV-1 integrase can displace POGZ from LEDGF/p75 in competition experiments. |

POGZ binds to the Bcl11a promoter and erythroid-specific intragenic regulatory regions; targeted deletion of Pogz in adult hematopoietic cells causes persistence of embryonic β-like globin expression. Knockdown of POGZ in human CD34+ erythroblasts reduces BCL11A expression and increases fetal hemoglobin, placing POGZ upstream of BCL11A in hemoglobin silencing. |

POGZ promotes the presence of HP1 at DNA double-strand breaks (DSBs) and is required for homology-directed DNA repair (HDR). Mechanistically, POGZ retains the BRCA1/BARD1 complex at DSBs in an HP1-dependent manner. POGZ depletion delays DSB resolution, sensitizes cells to cisplatin and talazoparib, and CRISPR inactivation of Pogz is embryonically lethal in mice; haploinsufficiency results in radiosensitivity and DSB accumulation in diverse tissues. |

POGZ silences the 2C transcriptional program and endogenous retroviruses (ERVs) in ESCs by associating with and recruiting TRIM28 and SETDB1; loss of POGZ decreases H3K9me3/H4K20me3 at Dux and ERV loci (IAPEy directly, MERVL indirectly), leading to upregulation of 2C transcripts and ESC transition to a 2C-like state. Activation of POGZ-bound ERVs is associated with upregulation of nearby neural disease genes. |

POGZ is a component of the PRC1.6 complex (PRC1.6-POGZ complex); POGZ elicits transcriptional repression dependent on RING1B expression. POGZ colocalizes with RING1B and HP1γ at regulatory genes in embryonic mouse cortical cells. In neuronal progenitor cells, POGZ ablation leads to widespread transcriptomic dysregulation and failed activation of key neuronal genes. PRC1.6-POGZ represses the BMP signaling pathway to regulate neuronal differentiation. |

POGZ is expressed in the suprachiasmatic nucleus (SCN) and exhibits circadian oscillations in hypothalamus and liver; its transcription is directly regulated by the circadian molecule DBP through a D-box element in its proximal enhancer. POGZ interacts with and enhances the transcriptional activity of CREB, a key regulator of light-induced phase resetting. Pogz-deficient mice show prolonged circadian period, impaired light-induced phase shift, and reduced SCN c-Fos activation in response to light. |
