F-box domain found in F-box/LRR-repeat protein 10 (FBXL10) and similar proteins; FBXL10 is also called lysine-specific demethylase 2B (KDM2B), CXXC-type zinc finger protein 2 (CXXC2), F-box and leucine-rich repeat protein 10, F-box protein FBL10, JmjC domain-containing histone demethylation protein 1B (JHDM1B), Jumonji domain-containing EMSY-interactor methyltransferase motif protein, protein JEMMA, protein-containing CXXC domain 2, [Histone-H3]-lysine-36 demethylase 1B, or NDY1. It is a histone demethylase that catalyzes the demethylation of H3K4me3 and H3K36me2, thereby playing a central role in the histone code. It preferentially binds the transcribed region of ribosomal RNA and represses the transcription of ribosomal RNA genes which inhibits cell growth and proliferation. FBXL10 may also serve as the substrate-recognition component of an SCF (SKP1-CUL1-F-box protein)-type E3 ubiquitin ligase complex. The F-box domain has a role in mediating protein-protein interactions in a variety of contexts, such as polyubiquitination, transcription elongation, centromere binding and translational repression.

Antagonist of mitotic exit network protein 1; Amn1 has been functionally characterized in Saccharomyces cerevisiae as a component of the Antagonist of MEN pathway (AMEN). The AMEN network is activated by MEN (mitotic exit network) via an active Cdc14, and in turn switches off MEN. Amn1 constitutes one of the alternative mechanisms by which MEN may be disrupted. Specifically, Amn1 binds Tem1 (Termination of M-phase, a GTPase that belongs to the RAS superfamily), and disrupts its association with Cdc15, the primary downstream target. Amn1 is a leucine-rich repeat (LRR) protein, with 12 repeats in the S. cerevisiae ortholog. As a negative regulator of the signal transduction pathway MEN, overexpression of AMN1 slows the growth of wild type cells. The function of the vertebrate members of this family has not been determined experimentally, they have fewer LRRs that determine the extent of this model.

CXXC zinc finger domain; This domain contains eight conserved cysteine residues that bind to two zinc ions. The CXXC domain is found in a variety of chromatin-associated proteins. This domain binds to nonmethyl-CpG dinucleotides. The domain is characterized by two repeats, and shows a peculiar internal duplication in which the second unit is inserted into the first one. Each of these units is characterized by four conserved cysteines, displaying a CXXCXXCX(n)C motif that chelate a Zn+2 ion. The DNA binding interface has been identified by NMR. In eukaryotes, the CXXC domain is found in stramenopiles, plants and metazoans. Plants possess a mono-CXXC domain that is present in distinct chromatin proteins. Structural comparisons show that the mono-CXXC is homologous to the structural-zinc binding domain of medium chain dehydrogenases.

It is a ubiquitously expressed histone H3 lysine 36 (H3K36) demethylase that has been implicated in gene silencing, cell cycle, cell growth, and cancer development. It acts as a key negative regulator of gluconeogenic gene expression and plays a critical role in the invasiveness, proliferation, and anchorage-independent growth of non-small cell lung cancer (NSCLC) cells, as well as in the osteo/dentinogenic differentiation of Mesenchymal stem cells (MSCs). KDM2A regulates rRNA transcription in response to starvation and functions as a negative regulator of NF-kappaB. It is a heterochromatin-associated and HP1-interacting protein that promotes Heterochromatin Protein 1 (HP1) localization to chromatin. It is specifically recruited to CpG islands to define a unique chromatin architecture, which requires direct and specific interaction with linker DNA. It also functions as a H3K4 demethylase that regulates cell proliferation through p15 (INK4B) and p27 (Kip1) in stem cells from apical papilla (SCAPs). KDM2A belongs to the JmjC domain-containing histone demethylase family. KDM2A consists of two Jumonji domains (JmjN and JmjC), a CXXC zinc-finger domain, a plant homeodomain (PHD) finger, an F-box domain, followed by an antagonist of mitotic exit network protein 1 (AMN1) domain. This model corresponds to a small conserved region in KDM2A between the JmjC domain and the CXXC zinc-finger domain, which has been called the C-terminal domain by literature.

It plays an essential role in embryonic development and homeostasis by regulating cell proliferation and survival. FBXL11 may also recognize and bind to some phosphorylated proteins and promote their ubiquitination and degradation. It associates with centromeres and represses transcription of small non-coding RNAs that are encoded by the clusters of satellite repeats at the centromere. It is required to sustain centromeric integrity and genomic stability, particularly during mitosis. FBXL19, also called F-box and leucine-rich repeat protein 19, is the substrate-recognition component of an SCF-type E3 ubiquitin ligase complex. It acts as a CpG island-binding protein in mouse embryonic stem (ES) cells and has been shown to associate with the CDK-Mediator complex. It promotes H2Bub1 at the promoters of CpG island-containing genes by interacting with RNF20. The F-box domain has a role in mediating protein-protein interactions in a variety of contexts, such as polyubiquitination, transcription elongation, centromere binding and translational repression.

CXXC zinc finger domain; This domain contains eight conserved cysteine residues that bind to two zinc ions. The CXXC domain is found in a variety of chromatin-associated proteins. This domain binds to nonmethyl-CpG dinucleotides. The domain is characterized by two repeats, and shows a peculiar internal duplication in which the second unit is inserted into the first one. Each of these units is characterized by four conserved cysteines, displaying a CXXCXXCX(n)C motif that chelate a Zn+2 ion. The DNA binding interface has been identified by NMR. In eukaryotes, the CXXC domain is found in stramenopiles, plants and metazoans. Plants possess a mono-CXXC domain that is present in distinct chromatin proteins. Structural comparisons show that the mono-CXXC is homologous to the structural-zinc binding domain of medium chain dehydrogenases.

F-box domain found in uncharacterized F-box protein group similar to F-box only protein 3 (FBXO3); This subfamily corresponds to a group of uncharacterized F-box proteins which show sequence similarity to F-box only protein 3 (FBXO3). FBXO3, also called FBX3, is the substrate-recognition component of an SCF (SKP1-CUL1-F-box protein)-type E3 ubiquitin ligase complex, that mediates the ubiquitination of HIPK2 and probably that of EP300, leading to rapid degradation by the proteasome. It also promotes ubiquitylation and transcriptional activity of AIRE (autoimmune regulator). The F-box domain has a role in mediating protein-protein interactions in a variety of contexts, such as polyubiquitination, transcription elongation, centromere binding and translational repression.

Antagonist of mitotic exit network protein 1; Amn1 has been functionally characterized in Saccharomyces cerevisiae as a component of the Antagonist of MEN pathway (AMEN). The AMEN network is activated by MEN (mitotic exit network) via an active Cdc14, and in turn switches off MEN. Amn1 constitutes one of the alternative mechanisms by which MEN may be disrupted. Specifically, Amn1 binds Tem1 (Termination of M-phase, a GTPase that belongs to the RAS superfamily), and disrupts its association with Cdc15, the primary downstream target. Amn1 is a leucine-rich repeat (LRR) protein, with 12 repeats in the S. cerevisiae ortholog. As a negative regulator of the signal transduction pathway MEN, overexpression of AMN1 slows the growth of wild type cells. The function of the vertebrate members of this family has not been determined experimentally, they have fewer LRRs that determine the extent of this model.
