This model includes the ePHD finger of JMJD2C. JMJD2C, also termed lysine-specific demethylase 4C (KDM4C), or gene amplified in squamous cell carcinoma 1 protein (GASC-1 protein), or JmjC domain-containing histone demethylation protein 3C (JHDM3C), is an epigenetic factor that catalyzes the demethylation of di- and trimethylated H3K9 and H3K36, and may be involved in the development and/or progression of various types of cancer including esophageal squamous cell carcinoma (ESC) and breast cancer. It selectively interacts with hypoxia-inducible factor 1alpha (HIF1alpha) and plays a role in breast cancer progression. Moreover, JMJD2C may play an important role in the treatment of obesity and its complications by modulating the regulation of adipogenesis by nuclear receptor peroxisome proliferator-activated receptor gamma (PPARgamma). JMJD2C contains jmjN and jmjC domains in the N-terminal region, followed by a canonical plant homeodomain (PHD) finger, this non-canonical ePHD finger, and a Tudor domain.

Jumonji domain-containing protein 2A Tudor domain; This is the tudor domain found in histone demethylase Jumonji domain-containing protein 2A (JMJD2A). Structure and function analysis indicate that this domain can recognize equally well two unrelated histone peptides, H3K4me3 and H4K20me3, by means of two very different binding mechanisms. JMJD2 also known as KDM4, is a conserved iron (II)-dependent jumonji-domain demethylase subfamily that is essential during development. Vertebrate KDM4A-C proteins contain a conserved double tudor domain (DTD).

PHD zinc finger; The plant homeodomain (PHD) finger is a C4HC3 zinc-finger-like motif found in nuclear proteins thought to be involved in epigenetics and chromatin-mediated transcriptional regulation. The PHD finger binds two zinc ions using the so-called 'cross-brace' motif and is thus structurally related to the RING finger and the FYVE finger. It is not yet known if PHD fingers have a common molecular function. Several reports suggest that it can function as a protein-protein interacton domain and it was recently demonstrated that the PHD finger of p300 can cooperate with the adjacent BROMO domain in nucleosome binding in vitro. Other reports suggesting that the PHD finger is a ubiquitin ligase have been refuted as these domains were RING fingers misidentified as PHD fingers.

first Tudor domain found in Jumonji domain-containing protein 2 (JMJD2) family of histone demethylases; JMJD2 proteins, also called lysine-specific demethylase 4 histone demethylases (KDM4), have been implicated in various cellular processes including DNA damage response, transcription, cell cycle regulation, cellular differentiation, senescence, and carcinogenesis. They selectively catalyze the demethylation of di- and trimethylated H3K9 and H3K36. This model contains only three JMJD2 proteins, JMJD2A-C, which all contain jmjN and jmjC domains in the N-terminal region, followed by a canonical PHD domain, a noncanonical extended PHD domain, and tandem Tudor domains. The model corresponds to the first Tudor domain. The Tudor domain binds to proteins with dimethylated arginine or lysine residues, and may also bind methylated histone tails to facilitate protein-protein interactions. JMJD2D is not included in this model, since it lacks both the PHD and Tudor domains and has a different substrate specificity. JMJD2A-C are required for efficient cancer cell growth.

Extended PHD finger found in protein AF-10 and AF-17; The extended plant homeodomain (ePHD) zinc finger is characterized as Cys2HisCys5HisCys2His. This model includes the ePHD finger of AF-10 and AF-17. AF-10, also termed ALL1 (acute lymphoblastic leukaemia)-fused gene from chromosome 10 protein, is a transcription factor encoded by gene AF10, a translocation partner of the MLL (mixed-lineage leukaemia) oncogene in leukaemia. AF-10 has been implicated in the development of leukemia following chromosomal rearrangements between the AF10 gene and one of at least two other genes, MLL and CALM. It plays a key role in the survival of uncommitted hematopoietic cells. Moreover, AF-10 functions as a follistatin-related gene (FLRG)-interacting protein. The interaction with FLRG enhances AF10-dependent transcription. It interacts with the human counterpart of yeast Dot1, hDOT1L, and may act as a bridge for the recruitment of hDOT1L to the genes targeted by MLL-AF10. It also interacts with the synovial sarcoma associated protein SYT protein and may play a role in synovial sarcomas and acute leukemias. AF-17, also termed ALL1-fused gene from chromosome 17 protein, is encoded by gene AF17 that has been identified in hematological malignancies as translocation partners of the mixed lineage leukemia gene MLL. It is a putative transcription factor that may play a role in multiple signaling pathways. It is involved in chromatin-mediated gene regulation mechanisms. It functions as a component of the multi-subunit Dot1 complex (Dotcom) and plays a role in the Wnt/Wingless signaling pathway. It also seems to be a downstream target of the beta-catenin/T-cell factor pathway, and participates in G2-M progression. Moreover, it may function as an important regulator of ENaC-mediated Na+ transport and thus blood pressure. Both AF-10 and AF-17 contain an N-terminal plant homeodomain (PHD) finger followed by this non-canonical ePHD finger. The PHD finger is involved in their homo-oligomerization. In the C-terminal region, they possess a leucine zipper domain and a glutamine-rich region. This family also includes ZFP-1, the Caenorhabditis elegans AF10 homolog. It was originally identified as a factor promoting RNAi interference in C. elegans. It also acts as Dot1-interacting protein that opposes H2B ubiquitination to reduce polymerase II (Pol II) transcription.

This model includes the ePHD finger of Jade-1. Jade-1, also termed PHD finger protein 17 (PHF17), is a novel binding partner of von Hippel-Lindau (VHL) tumor suppressor Pvhl, a key regulator of cellular oxygen sensing pathway. It is highly expressed in renal proximal tubules. Jade-1 functions as an essential regulator of multiple cell signaling pathways. It may be involved in the Serine/threonine kinase AKT/AKT1 pathway during renal cancer pathogenesis and normally prevents renal epithelial cell proliferation and transformation. It also acts as a pro-apoptotic and growth suppressive ubiquitin ligase to inhibit canonical Wnt downstream effector beta-catenin for proteasomal degradation and ASA transcription factor associated with histone acetyltransferase activity and with increased abundance of cyclin-dependent kinase inhibitor p21. Moreover, Jade-1 is required for ING4 and ING5 to associate with histone acetyltransferase (HAT) HBO1 and Eaf6 to form a HBO1 complex, and plays a role in epithelial cell regeneration. It has also been identified as a novel component of the nephrocystin protein (NPHP) complex and interacts with the ciliary protein nephrocystin-4 (NPHP4). Jade-1 contains a canonical plant homeodomain (PHD) finger followed by this non-canonical ePHD finger, both of which are zinc-binding motifs.

Jumonji domain-containing protein 2A Tudor domain; This is the tudor domain found in histone demethylase Jumonji domain-containing protein 2A (JMJD2A). Structure and function analysis indicate that this domain can recognize equally well two unrelated histone peptides, H3K4me3 and H4K20me3, by means of two very different binding mechanisms. JMJD2 also known as KDM4, is a conserved iron (II)-dependent jumonji-domain demethylase subfamily that is essential during development. Vertebrate KDM4A-C proteins contain a conserved double tudor domain (DTD).

PHD finger found in Jumonji domain-containing protein 2 (JMJD2) family of histone demethylases; JMJD2 proteins, also termed lysine-specific demethylase 4 histone demethylases (KDM4), have been implicated in various cellular processes including DNA damage response, transcription, cell cycle regulation, cellular differentiation, senescence, and carcinogenesis. They selectively catalyze the demethylation of di- and trimethylated H3K9 and H3K36. This model contains only three JMJD2 proteins, JMJD2A-C, which all contain jmjN and jmjC domains in the N-terminal region, followed by a Cys4HisCys3 canonical PHD finger, a non-canonical extended PHD (ePHD) finger, Cys2HisCys5HisCys2His, and a Tudor domain. JMJD2D is not included in this family, since it lacks both PHD and Tudor domains and has a different substrate specificity. JMJD2A-C are required for efficient cancer cell growth. This model corresponds to the Cys4HisCys3 canonical PHD finger.

Extended PHD finger found in Saccharomyces cerevisiae SANT domain-containing protein 2 (Snt2p) and similar proteins; The extended plant homeodomain (ePHD) zinc finger is characterized as Cys2HisCys5HisCys2His. This model includes the ePHD finger of Snt2p. Sntp2 is a yeast protein that may function in multiple stress pathways. It coordinates the transcriptional response to hydrogen peroxide-mediated oxidative stress through interaction with Ecm5 and the Rpd3 deacetylase. Snt2p contains a bromo adjacent homology (BAH) domain, two canonical PHD fingers, a non-canonical ePHD finger, and a SANT (SWI3, ADA2, N-CoR and TFIIIB) DNA-binding domain.

Extended PHD finger 2 found in histone-lysine N-methyltransferase 2C (KMT2C) and 2D (KMT2D); The extended plant homeodomain (ePHD) zinc finger is characterized as Cys2HisCys5HisCys2His. This model corresponds to the second ePHD finger of KMT2C, and KMT2D. KMT2C, also termed myeloid/lymphoid or mixed-lineage leukemia protein 3 (MLL3), or homologous to ALR protein, is a histone H3 lysine 4 (H3K4) lysine methyltransferase that functions as a circadian factor contributing to genome-scale circadian transcription. It is a component of a large complex that acts as a coactivator of multiple transcription factors, including the bile acid (BA)-activated nuclear receptor, farnesoid X receptor (FXR), a critical player in BA homeostasis. The MLL3 complex is essential for p53 transactivation of small heterodimer partner (SHP). KMT2C is also a part of activating signal cointegrator-2 (ASC-2)-containing complex (ASCOM) that contains the transcriptional coactivator nuclear receptor coactivator 6 (NCOA6), KMT2C and its paralog MLL4. The ASCOM complex is critical for nuclear receptor (NR) activation of bile acid transporter genes and is down regulated in cholestasis. KMT2D, also termed ALL1-related protein (ALR), is encoded by the gene that was named MLL4, a fourth human homolog of Drosophila trithorax, located on chromosome 12. It enzymatically generates trimethylated histone H3 Lysine 4 (H3K4me3). It plays an essential role in differentiating the human pluripotent embryonal carcinoma cell line NTERA-2 clone D1 (NT2/D1) stem cells by activating differentiation-specific genes, such as HOXA1-3 and NESTIN. KMT2D is also a part of ASCOM. Both KMT2C and KMT2D contain the catalytic domain SET, five PHD fingers, two ePHD fingers, a RING finger, an HMG (high-mobilitygroup)-binding motif, and two FY-rich regions.
