PHD finger found in protein Jade-2 and similar proteins; Jade-2, also termed PHD finger protein 15 (PHF15), is a plant homeodomain (PHD) zinc finger protein that is closely related to Jade-1, which functions as an essential regulator of multiple cell signaling pathways. Like Jade-1, Jade-2 is required for ING4 and ING5 to associate with histone acetyltransferase (HAT) HBO1 and Eaf6 to form a HBO1 complex that has a histone H4-specific acetyltransferase activity, a reduced activity toward histone H3, and is responsible for the bulk of histone H4 acetylation in vivo. Jade-2 contains a canonical Cys4HisCys3 PHD finger followed by a non-canonical extended PHD (ePHD) finger, Cys2HisCys5HisCys2His, both of which are zinc-binding motifs. This model corresponds to the canonical Cys4HisCys3 PHD finger.

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.

Patatin-like phospholipase domain containing protein 1; Members of this family share a patatin domain, initially discovered in potato tubers. Some members of PNPLA1 subfamily do not have the lipase consensus sequence Gly-X-Ser-X-Gly which is essential for hydrolase activity. This family includes PNPLA1 from Homo sapiens and Gallus gallus. Currently, there is no literature available on the physiological role, structure, or enzymatic activity of PNPLA1. It is expressed in various human tissues in low mRNA levels.

This model includes the ePHD finger of Jade-1 (PHF17), Jade-2 (PHF15), and Jade-3 (PHF16); each of these proteins is required for ING4 and ING5 to associate with histone acetyltransferase (HAT) HBO1 and EAF6 to form a HBO1 complex that has a histone H4-specific acetyltransferase activity, has reduced activity toward histone H3, and is responsible for the bulk of histone H4 acetylation in vivo. This family also contains Drosophila melanogaster PHD finger protein rhinoceros (RNO). It is a novel plant homeodomain (PHD)-containing nuclear protein that may function as a transcription factor that antagonizes Ras signaling by regulating transcription of key EGFR/Ras pathway regulators in the Drosophila eye. All Jade proteins contain a canonical PHD finger followed by this non-canonical ePHD finger, both of which are zinc-binding motifs.

This model corresponds to the ePHD finger of the family of BRPF proteins, which includes BRPF1, BRD1/BRPF2, and BRPF3. These are scaffold proteins that form monocytic leukemic zinc-finger protein (MOZ)/MOZ-related factor (MORF) H3 histone acetyltransferase (HAT) complexes with other regulatory subunits, such as inhibitor of growth 5 (ING5) and Esa1-associated factor 6 ortholog (EAF6). BRPF proteins have multiple domains, including a plant homeodomain (PHD) zinc finger followed by a non-canonical ePHD finger, a bromodomain and a proline-tryptophan-tryptophan-proline (PWWP) domain. This PHD finger binds to lysine 4 of histone H3 (K4H3), the bromodomain interacts with acetylated lysines on N-terminal tails of histones and other proteins, and the PWWP domain shows histone-binding and chromatin association properties.

Extended PHD finger found in Arabidopsis thaliana ATX1, -2, and similar proteins; The extended plant homeodomain (ePHD) zinc finger is characterized as Cys2HisCys5HisCys2His. This subfamily includes the ePHD finger of A. thaliana histone-lysine N-methyltransferase arabidopsis trithorax-like proteins ATX1, -2, and similar proteins. ATX1 and -2 are sister paralogs originating from a segmental chromosomal duplication; they are plant counterparts of the Drosophila melanogaster trithorax (TRX) and mammalian mixed-lineage leukemia (MLL1) proteins. ATX1 (also known as protein SET domain group 27, or trithorax-homolog protein 1/TRX-homolog protein 1), is a methyltransferase that trimethylates histone H3 at lysine 4 (H3K4me3). It also acts as a histone modifier and as a positive effector of gene expression. ATX1 regulates transcription from diverse classes of genes implicated in biotic and abiotic stress responses. It is involved in dehydration stress signaling in both abscisic acid (ABA)-dependent and ABA-independent pathways. ATX2 (also known as protein SET domain group 30, or trithorax-homolog protein 2/TRX-homolog protein 2), is involved in dimethylating histone H3 at lysine 4 (H3K4me2). ATX1 and ATX2 are multi-domain proteins that consist of an N-terminal PWWP domain, FYRN- and FYRC (DAST, domain associated with SET in trithorax) domains, a canonical PHD finger, this non-canonical ePHD finger, and a C-terminal SET domain.

This subfamily includes the ePHD finger of KMT2B. KMT2B is also called trithorax homolog 2 or WW domain-binding protein 7 (WBP-7). KMT2B is encoded by the gene that was first named myeloid/lymphoid or mixed-lineage leukemia 2 (MLL2), a second human homolog of Drosophila trithorax, located on chromosome 19. It belongs to the MLL subfamily of H3K4-specific histone lysine methyltransferases (KMT2) and is vital for normal mammalian embryonic development. KMT2B functions as the catalytic subunit in the MLL2 complex, which contains WDR5, RbBP5, ASH2L and DPY30 as integral core subunits required for the efficient methylation activity of the complex. The MLL2 complex is highly active and specific for histone 3 lysine 4 (H3K4) methylation, which stimulates chromatin transcription in a SAM- and H3K4-dependent manner. Moreover, KMT2B plays a critical role in memory formation by mediating hippocampal H3K4 di- and trimethylation. It is also required for RNA polymerase II association and protection from DNA methylation at the MagohB CpG island promoter. KMT2B contains a CxxC (x for any residue) zinc finger domain, three PHD fingers, this ePHD finger, two FY (phenylalanine tyrosine)-rich domains, and a SET (Suppressor of variegation, Enhancer of zeste, Trithorax) domain.

PHD finger 1 found in PHD finger protein 14 (PHF14) and similar proteins; PHF14 is a novel nuclear transcription factor that controls the proliferation of mesenchymal cells by directly repressing platelet-derived growth factor receptor-alpha (PDGFRalpha) expression. It also acts as an epigenetic regulator and plays an important role in the development of multiple organs in mammals. PHF14 contains three canonical plant homeodomain (PHD) fingers and a non-canonical extended PHD (ePHD) finger, Cys2HisCys5HisCys2His. It can interact with histones through its PHD fingers. The model corresponds to the first PHD finger.

Extended PHD finger found in histone-lysine N-methyltransferase 2A (KMT2A) and 2B (KMT2B); The extended plant homeodomain (ePHD) zinc finger is characterized as Cys2HisCys5HisCys2His. This subfamily includes the ePHD finger of histone-lysine N-methyltransferase trithorax (Trx) like proteins, KMT2A/MLL1 and KMT2B/MLL2. KMT2A and KMT2B comprise the mammalian Trx branch of COMPASS family, and are both essential for mammalian embryonic development. KMT2A regulates chromatin-mediated transcription through the catalysis of methylation of histone 3 lysine 4 (H3K4), and is frequently rearranged in acute leukemia. KMT2A functions as the catalytic subunit in the MLL1 complex. KMT2B is a second human homolog of Drosophila trithorax, located on chromosome 19 and functions as the catalytic subunit in the MLL2 complex. It plays a critical role in memory formation by mediating hippocampal H3K4 di- and trimethylation. It is also required for RNA polymerase II association and protection from DNA methylation at the MagohB CpG island promoter. Both KMT2A and KMT2B contain a CxxC (x for any residue) zinc finger domain, three PHD fingers, this extended PHD (ePHD) finger, two FY (phenylalanine tyrosine)-rich domains, and a SET (Suppressor of variegation, Enhancer of zeste, Trithorax) domain.
