PHD finger 2 and 3 found in bromodomain and PHD finger-containing transcription factor (BPTF); BPTF, also termed nucleosome-remodeling factor subunit BPTF, or fetal Alz-50 clone 1 protein (FAC1), or fetal Alzheimer antigen, functions as a transcriptional regulator that exhibits altered expression and subcellular localization during neuronal development and neurodegenerative diseases such as Alzheimer's disease. It interacts with the human orthologue of the Kelch-like Ech-associated protein (Keap1). Its function and subcellular localization can be regulated by Keap1. Moreover, BPTF is a novel DNA-binding protein that recognizes the DNA sequence CACAACAC and represses transcription through this site in a phosphorylation-dependent manner. Furthermore, BPTF interacts with the Myc-associated zinc finger protein (ZF87/MAZ) and alters its transcriptional activity, which has been implicated in gene regulation in neurodegeneration. Some family members contain two or three plant homeodomain (PHD) fingers, which may be involved in complex formation with histone H3 trimethylated at K4 (H3K4me3). This family corresponds to the second and third PHD fingers.

Williams-Beuren syndrome DDT (WSD), D-TOX E motif; This family represents the combined alpha-helical module found in diverse eukaryotic chromatin proteins. Based on the Ioc3 structure, the N-terminus of this module is inferred to interact with nucleosomal linker DNA and the SLIDE domain of ISWI proteins. The resulting complex forms a protein ruler that measures out the spacing between two adjacent nucleosomes. The acidic residue from the GxD signature at the N-terminus is a major determinant of the interaction between the ISWI and WHIM motifs. The N-terminal portion also contacts the inter-nucleosomal linker DNA. The module shows a great domain architectural diversity and is often combined with other modified histone peptide recognizing and DNA binding domains, some of which discriminate methylated DNA. The WSD module constitutes the inter-nucleosomal linker DNA binding site in the major groove of DNA, and was first identified as WSD, the D-TOX E motif of plant homeodomains homologous with the mutant transcription factor causing Williams-Beuren syndrome in association with the DDT-domain.

DDT domain; The DDT domain is named after (DNA binding homeobox and Different Transcription factors) and is approximately 60 residues in length. Along with the WHIM motifs, it comprises an entirely alpha helical module found in diverse eukaryotic chromatin proteins. Based on the structure of Ioc3, this module is inferred to interact with nucleosomal linker DNA and the SLIDE domain of ISWI proteins. The resulting complex forms a protein ruler that measures out the spacing between two adjacent nucleosomes. In particular, the DDT domain, in combination with the WHIM1 and WHIM2 motifs form the SLIDE domain binding pocket.

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.

High molecular weight glutenin subunit; Members of this family include high molecular weight subunits of glutenin. This group of gluten proteins is thought to be largely responsible for the elastic properties of gluten, and hence, doughs. Indeed, glutenin high molecular weight subunits are classified as elastomeric proteins, because the glutenin network can withstand significant deformations without breaking, and return to the original conformation when the stress is removed. Elastomeric proteins differ considerably in amino acid sequence, but they are all polymers whose subunits consist of elastomeric domains, composed of repeated motifs, and non-elastic domains that mediate cross-linking between the subunits. The elastomeric domain motifs are all rich in glycine residues in addition to other hydrophobic residues. High molecular weight glutenin subunits have an extensive central elastomeric domain, flanked by two terminal non-elastic domains that form disulphide cross-links. The central elastomeric domain is characterized by the following three repeated motifs: PGQGQQ, GYYPTS[P/L]QQ, GQQ. It possesses overlapping beta-turns within and between the repeated motifs, and assumes a regular helical secondary structure with a diameter of approx. 1.9 nm and a pitch of approx. 1.5 nm.

Furthermore, BPTF interacts with the Myc-associated zinc finger protein (ZF87/MAZ) and alters its transcriptional activity, which has been implicated in gene regulation in neurodegeneration. Some family members contain two or three plant homeodomain (PHD) fingers, which may be involved in complex formation with histone H3 trimethylated at K4 (H3K4me3). This family corresponds to the second and third PHD fingers.

PHD finger found in PHF2, PHF8 and KDM7; This family includes PHF2, PHF8, KDM7, and similar proteins. PHF2, also termed GRC5, or PHD finger protein 2, is a histone lysine demethylase ubiquitously expressed in various tissues. PHF8, also termed PHD finger protein 8, or KDM7B, is a monomethylated histone H4 lysine 20(H4K20me1) demethylase that transcriptionally regulates many cell cycle genes. It also preferentially acts on H3K9me2 and H3K9me1. PHF8 is modulated by CDC20-containing anaphase-promoting complex (APC (cdc20)) and plays an important role in the G2/M transition. It acts as a critical molecular sensor for mediating retinoic acid (RA) treatment response in RAR alpha-fusion-induced leukemia. Moreover, PHF8 is essential for cytoskeleton dynamics and is associated with X-linked mental retardation. KDM7, also termed JmjC domain-containing histone demethylation protein 1D (JHDM1D), or KIAA1718, is a dual histone demethylase that catalyzes demethylation of monomethylated and dimethylated H3K9 (H3K9me2/me1) and H3K27 (H3K27me2/me1), which functions as an eraser of silencing marks on chromatin during brain development. It also plays a tumor-suppressive role by regulating angiogenesis. All family members contain a plant homeodomain (PHD) finger and a JmjC domain.

DDT domain; The DDT domain is named after (DNA binding homeobox and Different Transcription factors) and is approximately 60 residues in length. Along with the WHIM motifs, it comprises an entirely alpha helical module found in diverse eukaryotic chromatin proteins. Based on the structure of Ioc3, this module is inferred to interact with nucleosomal linker DNA and the SLIDE domain of ISWI proteins. The resulting complex forms a protein ruler that measures out the spacing between two adjacent nucleosomes. In particular, the DDT domain, in combination with the WHIM1 and WHIM2 motifs form the SLIDE domain binding pocket.

PHD finger found in PHD finger protein 3 (PHF3), and death-inducer obliterator variants Dido1, Dido2, and Dido3; PHF3 is a human homolog of yeast protein bypass of Ess1 (Bye1), a nuclear protein with a domain resembling the central domain in the transcription elongation factor TFIIS. It is ubiquitously expressed in normal tissues including brain, but its expression is significantly reduced or lost in glioblastomas. PHF3 contains an N-terminal plant homeodomain (PHD) finger, a central RNA polymerase II (Pol II)-binding TFIIS-like domain (TLD) domain, and a C-terminal Spen paralogue and orthologue C-terminal (SPOC) domain. This family also includes Dido gene encoding three alternative splicing variants (Dido1, 2, and 3), which have been implicated in a number of cellular processes such as apoptosis and chromosomal segregation, particularly in the hematopoietic system. Dido1 is important for maintaining embryonic stem (ES) cells and directly regulates the expression of pluripotency factors. It is the shortest isoform that contains only a highly conserved PHD finger responsible for the binding of histone H3 with a higher affinity for trimethylated lysine4 (H3K4me3). Gene Dido1 is a Bone morphogenetic protein (BMP) target gene and promotes BMP-induced melanoma progression. It also triggers apoptosis after nuclear translocation and caspase upregulation. Dido3 is the largest isoform and is ubiquitously expressed in all human tissues. It is dispensable for ES cell self-renewal and pluripotency, but is involved in the maintenance of stem cell genomic stability and tumorigenesis. Dido3 contains a PHD finger, a transcription elongation factor S-II subunit M (TFSIIM) domain, a SPOC module, and a long C-terminal region (CT) of unknown homology.

PHF2 also has dimethylated histone H3 lysine 9(H3K9me2) demethylase activity and acts as a coactivator of several metabolism-related transcription factors. Moreover, it can demethylate ARID5B and further forms a complex with demethylated ARD5B to bind the promoter regions of target genes. The overexpression of PHF2 is involved in the progression of esophageal squamous cell carcinoma (ESCC).

Bromodomain, polybromo repeat IV. Polybromo is a nuclear protein of unknown function, which contains 6 bromodomains. The human ortholog BAF180 is part of a SWI/SNF chromatin-remodeling complex, and it may carry out the functions of Yeast Rsc-1 and Rsc-2. It was shown that polybromo bromodomains bind to histone H3 at specific acetyl-lysine positions. Bromodomains are found in many chromatin-associated proteins and in nuclear histone acetyltransferases. They interact specifically with acetylated lysine, but not all the bromodomains in polybromo may bind to acetyl-lysine.

PHD finger found in CXXC-type zinc finger protein 1 (Cfp1); Cfp1, also termed CpG-binding protein, or PHD finger and CXXC domain-containing protein 1 (PCCX1), is a specificity factor that binds to unmethylated CpGs and links H3K4me3 with CpG islands (CGIs). It integrates both promoter CpG content and gene activity for accurate trimethylation of histone H3 Lys 4 (H3K4me3) deposition in embryonic stem cells. Moreover, Cfp1 is an essential component of the SETD1 histone H3K4 methyltransferase complex and functions as a critical regulator of histone methylation, cytosine methylation, cellular differentiation, and vertebrate development. Cfp1 contains a plant homeodomain (PHD) finger, a CXXC domain, and a CpG binding protein zinc finger C-terminal domain. Its CXXC domain selectively binds to non-methylated CpG islands, following by a preference for a guanosine nucleotide.

PHD finger found in the transcriptional intermediary factor 1 (TIF1) family and similar proteins; The TIF1 family of transcriptional cofactors includes TIF1alpha (TRIM24), TIF1beta (TRIM28), TIF1gamma (TRIM33), and TIF1delta (TRIM66), which are characterized by an N-terminal RING-finger B-box coiled-coil (RBCC/TRIM) motif and plant homeodomain (PHD) finger followed by a bromodomain in the C-terminal region. TIF1 proteins couple chromatin modifications to transcriptional regulation, signaling, and tumor suppression. They exert a deacetylase-dependent silencing effect when tethered to a promoter region. TIF1alpha, TIF1beta, and TIF1delta can homodimerize and contain a PXVXL motif necessary and sufficient for heterochromatin protein 1(HP1) binding. TIF1alpha and TIF1beta bind nuclear receptors and Kruppel-associated boxes (KRAB) specifically and respectively. In contrast, TIF1delta appears to lack nuclear receptor- and KRAB-binding activity. Moreover, TIF1delta is specifically involved in heterochromatin-mediated gene silencing during postmeiotic phases of spermatogenesis. TIF1gamma is structurally closely related to TIF1alpha and TIF1beta, but has very little functional features in common with them. It does not interact with the KRAB silencing domain of KOX1 or the heterochromatinic proteins HP1alpha, beta, and gamma. It cannot bind to nuclear receptors (NRs). This family also includes Sp100/Sp140 family proteins, the nuclear body SP100 and SP140. Sp110 is a leukocyte-specific component of the nuclear body. It may function as a nuclear hormone receptor transcriptional coactivator that may play a role in inducing differentiation of myeloid cells. It is also involved in resisting intracellular pathogens and functions as an important drug target for preventing intracellular pathogen diseases, such as tuberculosis, hepatic veno-occlusive disease, and intracellular cancers. SP140 is an interferon inducible nuclear leukocyte-specific protein involved in primary biliary cirrhosis and a risk factor in chronic lymphocytic leukemia. It is also implicated in innate immune response to human immunodeficiency virus type 1 (HIV-1) by binding to the virus viral infectivity factor (Vif) protein. Both Sp110 and Sp140 contain a SAND domain, a plant homeodomain (PHD) finger, and a bromodomain (BRD).
