JMJD1C is a histone/protein demethylase that demethylates MDC1 at Lys45, promoting MDC1-RNF8 interaction, RNF8-dependent MDC1 ubiquitylation, and recruitment of the RAP80-BRCA1 complex to DNA double-strand breaks. JMJD1C binds both RNF8 and MDC1 directly, is stabilized by RNF8 interaction, and is recruited to DSBs where it specifically regulates the BRCA1 branch (but not 53BP1 branch) of the DNA damage response. |

JMJD1C specifically demethylates histone H3K9 mono- and di-methylation and mediates transcriptional activation. It forms a complex with WHISTLE (a histone methyltransferase) and HSP90α. In mouse testis, JMJD1C and WHISTLE sequentially occupy the p450c17 promoter via SF-1: WHISTLE represses transcription prepubertally, then JMJD1C replaces it to activate steroidogenesis target genes. |

JMJD1C functions as a transcriptional coactivator for RUNX1-RUNX1T1 (AML1-ETO) in AML. It is directly recruited by RUNX1-RUNX1T1 to target gene loci and maintains low H3K9me2 levels at these loci to sustain their expression. Loss of JMJD1C in knockout mice impairs RUNX1-RUNX1T1-driven proliferation. |

JMJD1C directly interacts with HOXA9 and modulates a HOXA9-controlled gene-expression program required for MLL-AF9 and HOXA9-driven leukemia stem cell (LSC) self-renewal. Loss of JMJD1C substantially decreases LSC frequency and causes differentiation of these leukemias, while having only minor effects on normal hematopoietic stem cells. |

JMJD1C is phosphorylated at Thr505 by mTOR complex in response to feeding/insulin, enabling its direct interaction with USF-1 and recruitment to lipogenic gene promoters (e.g., FASN, GPAT). At these promoters, JMJD1C demethylates H3K9me2 to increase chromatin accessibility and activate transcription of lipogenic genes, thereby promoting hepatic and plasma triglyceride synthesis. |

JMJD1C demethylates STAT3 at Lys140 (a non-histone substrate) in B cells, which promotes STAT3 interaction with phosphatase PTPN6 and restricts sustained STAT3 phosphorylation. Loss of JMJD1C causes STAT3 Lys140 hypermethylation, blocking PTPN6 binding, sustaining STAT3 phosphorylation, and driving plasma cell differentiation. STAT3 K140R point mutation completely abrogates the effect of JMJD1C deletion. |

A splice variant of JMJD1C (s-JMJD1C) binds directly to the androgen receptor (AR) via its ligand-binding domain. s-JMJD1C is a nuclear-localized protein that functions as an AR coactivator, identified by yeast two-hybrid and validated by GST pull-down and mammalian one-hybrid assays. |

JMJD1C, as an H3K9 demethylase, binds the miR-302 promoter in human embryonic stem cells (hESCs) and reduces H3K9 methylation there to sustain miR-302 expression, thereby repressing neural differentiation. JMJD1C knockdown reduces BMP signaling, enhances TGFβ signaling, and elevates NR2F2, collectively promoting neural differentiation upon bFGF withdrawal. |

Deltex2 directly inhibits Jmjd1c demethylase activity by promoting its monoubiquitination; mutation of the monoubiquitination site in Jmjd1c abolishes Deltex2's inhibitory effect. Jmjd1c is required for MyoD expression in vivo and in vitro by demethylating H3K9me2 at a key regulatory region of the MyoD locus, thereby promoting myogenic differentiation. |

JMJD1C, with the help of pluripotency factor KLF4, maintains mouse ESC identity by demethylating H3K9 at promoters of the miR-200 family and miR-290/295 cluster, suppressing ERK/MAPK signaling and EMT. Jmjd1c depletion activates ERK/MAPK signaling, and ERK/MAPK inhibition rescues the differentiation phenotype. |

The catalytic JmjC domain and zinc finger domain of JMJD1C are required for leukemia cell survival in vitro and in vivo in MLL-rearranged AML. H3K36 methylation serves as a marker for JMJD1C activity at gene loci. Loss of JmjC domain activity leads to increased RAS/MAPK and JAK-STAT pathway activation and upregulation of IL-3 receptor genes, with activating RAS mutations conferring resistance to JMJD1C loss. |
