Background Information JARID1B (jumonji AT rich interactive domain 1B), also known as KDM5B, is histone demethylase with a preference for mono, di, and trimethylated lysine 4 of histone H3. Demethylation of lysine 4 in histone 3 is commonly associated with transcriptional repression. This nuclear protein belongs to the ARID family of DNA binding proteins and is highly expressed in a large number of breast cancers. This protein has been linked to the repressinion of multiple tumor suppressor genes including BRCA1 and HOXA5.

UniProt Number
UniProt Summary FUNCTION: Histone demethylase that demethylates 'Lys-4' of histone H3, thereby playing a central role in histone code. Does not demethylate histone H3 'Lys-9' or H3 'Lys-27'. Demethylates trimethylated, dimethylated and monomethylated H3 'Lys-4'. Acts as a transcriptional corepressor for FOXG1B and PAX9. Favors the proliferation of breast cancer cells by repressing tumor suppressor genes such as BRCA1 and HOXA5. In contrast, may act as a tumor suppressor for melanoma.

COFACTOR: Binds 1 Fe2+ ion per subunit (By similarity).

SUBUNIT STRUCTURE: Interacts with FOXG1B, PAX9, MYC, MYCN and RB1. Interacts with HDAC1, HDAC4, HDAC5 and HDAC7 (By similarity).

SUBCELLULAR LOCATION: Nucleus

TISSUE SPECIFICTY: Ubiquitously expressed, with highest levels in testis. Down-regulated in melanoma and glioblastoma. Up-regulated in breast cancer (at protein level). DOMAIN: Both the JmjC domain and the JmjN domain are required for enzymatic activity.

The 2 first PHD-type zinc finger domains are required for transcription repression activity.

SEQUENCE SIMILARITIES: Belongs to the JARID1 histone demethylase family.

Contains 1 ARID domain.

Contains 1 JmjC domain.

Contains 1 JmjN domain.

Contains 3 PHD-type zinc fingers.

SEQUENCE CAUTION: The sequence CAB63108.1 differs from that shown. Reason: Erroneous initiation. Translation N-terminally shortened.
Molecular Weight ~180 kDa observed. Uncharacterized bands may be observed at ~ 48 and 53 kDa in some lysates.
