F-box domain found in Arabidopsis thaliana transport inhibitor response 1 protein (TIR1), coronatine-insensitive protein 1 (COI1) and similar proteins; TIR1, also called F-box/LRR-repeat protein 1 (FBL1), is part of an SCF (SKP1-cullin-F-box) protein ligase complex that promotes the ubiquitin-dependent proteolysis of a family of transcriptional regulators known as Aux/IAAs in an auxin-dependent manner. TIR1 is an auxin receptor that plays a potential role in plant hormone signaling. COI1, also called F-box/LRR-repeat protein 2 (FBL2), is the substrate-recruiting module of an SCF ubiquitin E3 ligase complex. It mediates jasmonate signalling by promoting hormone-dependent ubiquitylation and degradation of transcriptional repressor JASMONATE ZIM-domain (JAZ) family proteins. This subfamily also includes Arabidopsis thaliana EIN3-binding F-box protein 1 (EBF1). EBF1, also called F-box/LRR-repeat protein 6 (FBL6), is a component of the SCF(EBF1) E3 ubiquitin ligase complex, which may mediate the ubiquitination and subsequent proteasomal degradation of target proteins (probably including EIN3 and EIL1). 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.

F-box domain superfamily; This short domain is commonly found at the N-terminus of various proteins, and typically co-occurs with one or more other conserved domains or motifs, such as leucine rich repeats, WD40 repeats, kelch, tub, spry, and others. 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. One of the best researched roles of F-box proteins is their participation in SCF (Skp1-Cul1-F-box protein), a multi-protein complex that functions as a ubiquitin E3 ligase, where the role of the F-box protein is to recruit target substrates. Gene families containing the F-box are found greatly expanded in narrow taxonomic lineages, such as flowering plants and nematodes. In this hierarchical classification, many of the subfamilies are named according to their domain architectures.

FBXL10 is also called lysine-specific demethylase 2B (KDM2B), CXXC-type zinc finger protein 2 (CXXC2), F-box and leucine-rich repeat protein 10 (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. FBXL11, also called KDM2A, CXXC8, F-box and leucine-rich repeat protein 11, F-box protein FBL7, F-box protein Lilina, JmjC domain-containing histone demethylation protein 1A (JHDM1A), or [Histone-H3]-lysine-36 demethylase 1A, is a histone H3 lysine 36 (H3K36) demethylase that regulates epithelial mesenchymal transition (EMT) and the metastasis of ovarian cancer. 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.
