 19-226 4.94e-75

type II C2 domain found in suppressor of zeste 12 protein (SUZ12) and similar proteins; SUZ12, also called chromatin precipitated E2F target 9 protein (ChET 9 protein), or joined to JAZF1 protein, is a Polycomb group (PcG) protein that is a component of the PRC2/EED-EZH2 complex, which methylates 'Lys-9' (H3K9me) and 'Lys-27' (H3K27me) of histone H3, leading to transcriptional repression of the affected target gene. The PRC2/EED-EZH2 complex may also serve as a recruiting platform for DNA methyltransferases, thereby linking two epigenetic repression systems. SUZ12 is also involved in various cellular processes, including cell differentiation, proliferation, and apoptosis, and is frequently overexpressed in cancer cells. The model corresponds to the noncanonical type II C2 domain of SUZ12, which shares notable structural homology with the classical C2 domains and plays a role in protein-protein interactions that may contribute to its diverse functions.

This model corresponds to the VEFS (VRN2-EMF2-FIS2-Su(z)12) box at the C-terminus of SUZ12, which is responsible for binding to EED and EZH2.

VEFS-Box of polycomb protein; The VEFS-Box (VRN2-EMF2-FIS2-Su(z)12) box is the C-terminal region of these proteins, characterized by an acidic cluster and a tryptophan/methionine-rich sequence, the acidic-W/M domain. Some of these sequences are associated with a zinc-finger domain about 100 residues towards the N-terminus. This protein is one of the polycomb cluster of proteins which control HOX gene transcription as it functions in heterochromatin-mediated repression.

zinc finger-binding (ZnB) and C2H2-type zinc finger (Zn) domain found in suppressor of zeste 12 protein (SUZ12) and similar proteins; Suppressor of zeste 12 protein (SUZ12), also called chromatin precipitated E2F target 9 protein (ChET 9 protein), or joined to JAZF1 protein, is a Polycomb group (PcG) protein that acts as a component of the Polycomb Repressive Complex 2 (PRC2)/EED-EZH2 complex, which methylates 'Lys-9' (H3K9me) and 'Lys-27' (H3K27me) of histone H3, leading to transcriptional repression of the affected target gene. The PRC2/EED-EZH2 complex may also serve as a recruiting platform for DNA methyltransferases, thereby linking two epigenetic repression systems. This model corresponds to a unique structural ZnB-Zn platform consisting of zinc finger-binding (ZnB) and C2H2-type zinc finger (Zn), which forms an intramolecular complex that governs the mutual exclusive binding of Jarid2 and EPOP in PRC2 holo complexes.

VEFS (VRN2-EMF2-FIS2-Su(z)12) box family; This family corresponds to a group of polycomb cluster proteins which control HOX gene transcription, as they function in heterochromatin-mediated repression. They are characterized by containing a VEFS-box in the C-terminal region, which is an acidic cluster and a tryptophan/methionine-rich sequence, the acidic-W/M domain. Some of these sequences are associated with a zinc-finger domain about 100 residues towards the N-terminus. Members include suppressor of zeste 12 protein (SUZ12) from vertebrates, plants, insects and fungi, as well as Polycomb group protein EMBRYONIC FLOWER 2 (EMF2), Polycomb group protein FERTILIZATION-INDEPENDENT SEED 2 (FIS2), and Polycomb group protein VERNALIZATION 2 (VRN2) from plants.

 289-360 7.68e-36

zinc finger-binding (ZnB) and C2H2-type zinc finger (Zn) domain found in suppressor of zeste 12 protein (SUZ12), and similar proteins; This family includes a group of Polycomb group (PcG) proteins from metazoa and plants, such as suppressor of zeste 12 protein (SUZ12), and Polycomb group proteins EMBRYONIC FLOWER 2 (EMF2) and FERTILIZATION-INDEPENDENT SEED 2 (FIS2). SUZ12 (also called chromatin precipitated E2F target 9 protein (ChET 9 protein), or joined to JAZF1 protein) is a component of the Polycomb Repressive Complex 2 (PRC2)/EED-EZH2 complex, which methylates 'Lys-9' (H3K9me) and 'Lys-27' (H3K27me) of histone H3, leading to transcriptional repression of the affected target gene. The PRC2/EED-EZH2 complex may also serve as a recruiting platform for DNA methyltransferases, thereby linking two epigenetic repression systems. EMF2 is involved in flowering processes by repressing unknown target genes and preventing reproductive development. It participates in polycomb group (PcG) protein complex-mediated (probably in complex with EMF1) silencing of the flower homeotic genes AGAMOUS (AG), PISTILLATA (PI), and APETALA3 (AP3), as well as of some regulatory genes such as ABSCISIC ACID INSENSITIVE3 (ABI3), LONG VEGETATIVE PHASE1 (LOV1), and FLOWERING LOCUS C (FLC) during vegetative development, by mediating trimethylation of histone 3 lysine 27 on the AG chromatin (H3K27me3). FIS2 is required to prevent the proliferation of the central cell by repressing unknown target genes before fertilization. It regulates the anteroposterior organization of the endosperm. Members in this family contain a unique structural ZnB-Zn platform consisting of zinc finger-binding (ZnB) and C2H2-type zinc finger (Zn).

VEFS (VRN2-EMF2-FIS2-Su(z)12) box found in Arabidopsis thaliana Polycomb group protein EMBRYONIC FLOWER 2 (EMF2) and similar proteins; This subfamily includes a group of proteins similar to Arabidopsis thaliana Polycomb group (PcG) proteins, EMF2, Polycomb group protein FERTILIZATION-INDEPENDENT SEED 2 (FIS2), and Polycomb group protein VERNALIZATION 2 (VRN2). EMF2 is involved in flowering processes by repressing unknown target genes and preventing reproductive development. It participates in PcG protein complex-mediated (probably in complex with EMF1) silencing of the flower homeotic genes AGAMOUS (AG), PISTILLATA (PI), and APETALA3 (AP3), as well as of some regulatory genes such as ABSCISIC ACID INSENSITIVE3 (ABI3), LONG VEGETATIVE PHASE1 (LOV1), and FLOWERING LOCUS C (FLC) during vegetative development, by mediating trimethylation of histone 3 lysine 27 on the AG chromatin (H3K27me3). FIS2 is required to prevent the proliferation of the central cell by repressing unknown target genes before fertilization. It regulates the anteroposterior organization of the endosperm. VRN2 plays a central role in vernalization by maintaining repressed the homeotic gene FLC, a floral repressor, after cold treatment. PcG proteins act by forming multiprotein complexes, which are required to maintain the transcriptionally repressive state of homeotic genes throughout development. Members of this family contain a VEFS (VRN2-EMF2-FIS2-Su(z)12) box.

VEFS (VRN2-EMF2-FIS2-Su(z)12) box found in Chaetomium thermophilum suppressor of zeste 12 protein (ctSUZ12) and similar proteins; SUZ12 is a Polycomb group (PcG) protein that acts as a component of the Polycomb Repressive Complex 2 (PRC2), a histone methyltransferase complex composed of core subunits EZH2 (or EZH1), EED, SUZ12 and Rbbp4. PRC2 trimethylates histone H3K27 (H3K27me3) to mark developmentally repressed chromatin. This model corresponds to the VEFS (VRN2-EMF2-FIS2-Su(z)12) box at the C-terminus of SUZ12, which is responsible for binding to EED and EZH2 (or EZH1).

zinc finger-binding (ZnB) and C2H2-type zinc finger (Zn) domain found in Arabidopsis thaliana Polycomb group protein EMBRYONIC FLOWER 2 (EMF2), and similar proteins; This family includes a group of plant proteins similar to Arabidopsis thaliana Polycomb group (PcG) proteins EMF2 and FERTILIZATION-INDEPENDENT SEED 2 (FIS2). EMF2 is involved in flowering processes by repressing unknown target genes and preventing reproductive development.

FIS2 is required to prevent the proliferation of the central cell by repressing unknown target genes before fertilization. It regulates the anteroposterior organization of the endosperm. Members in this family show high sequence similarity with a unique structural ZnB-Zn platform found in metazoan, which consists of zinc finger-binding (ZnB) and C2H2-type zinc finger (Zn).
