MNT (gene)
MNT (Max-binding protein MNT) is a Max-binding protein that is encoded by the ''MNT'' gene Function The Myc/Max/Mad network comprises a group of transcription factors that co-interact to regulate gene-specific transcriptional activation or repression. This gene encodes a protein member of the Myc/Max/Mad network. This protein has a basic-Helix-Loop-Helix-zipper domain (bHLHzip) with which it binds the canonical DNA sequence CANNTG, known as the E box, following heterodimerization with Max proteins. Its delta signature is 44. This protein is a transcriptional repressor and an antagonist of Myc-dependent transcriptional activation and cell growth. This protein represses transcription by binding to DNA and recruiting Sin3 corepressor proteins through its N-terminal Sin3-interaction domain Interactions MNT (gene) has been shown to interact with MLX, SIN3A Paired amphipathic helix protein Sin3a is a protein that in humans is encoded by the ''SIN3A'' gene.

Protein
Proteins are large biomolecules and macromolecules that comprise one or more long chains of amino acid residues. Proteins perform a vast array of functions within organisms, including catalysing metabolic reactions, DNA replication, responding to stimuli, providing structure to cells and organisms, and transporting molecules from one location to another. Proteins differ from one another primarily in their sequence of amino acids, which is dictated by the nucleotide sequence of their genes, and which usually results in protein folding into a specific 3D structure that determines its activity. A linear chain of amino acid residues is called a polypeptide. A protein contains at least one long polypeptide. Short polypeptides, containing less than 20–30 residues, are rarely considered to be proteins and are commonly called peptides. The individual amino acid residues are bonded together by peptide bonds and adjacent amino acid residues. The sequence of amino acid residue ...

Gene
In biology, the word gene (from , ; "...Wilhelm Johannsen coined the word gene to describe the Mendelian units of heredity..." meaning ''generation'' or ''birth'' or ''gender'') can have several different meanings. The Mendelian gene is a basic unit of heredity and the molecular gene is a sequence of nucleotides in DNA that is transcribed to produce a functional RNA. There are two types of molecular genes: protein-coding genes and noncoding genes. During gene expression, the DNA is first copied into RNA. The RNA can be directly functional or be the intermediate template for a protein that performs a function. The transmission of genes to an organism's offspring is the basis of the inheritance of phenotypic traits. These genes make up different DNA sequences called genotypes. Genotypes along with environmental and developmental factors determine what the phenotypes will be. Most biological traits are under the influence of polygenes (many different genes) as well as gen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
MLX (gene)
Max-like protein X is a protein that in humans is encoded by the ''MLX'' gene. Function The product of this gene belongs to the family of basic helix-loop-helix leucine zipper (bHLH-Zip) transcription factors. These factors form heterodimers with Mad proteins and play a role in proliferation, determination and differentiation. This gene product may act to diversify Mad family function by its restricted association with a subset of the Mad family of transcriptional repressors, namely Mad1 and Mad4. Alternatively spliced transcript variants encoding different isoforms have been identified for this gene. Interactions MLX (gene) has been shown to interact with MNT, MXD1 and MLXIPL. MLX must dimerize with MondoA or with MLXIPL (carbohydrate-responsive element-binding protein Carbohydrate-responsive element-binding protein (ChREBP) also known as MLX-interacting protein-like (MLXIPL) is a protein that in humans is encoded by the ''MLXIPL'' gene. The protein name derives from ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
SIN3A
Paired amphipathic helix protein Sin3a is a protein that in humans is encoded by the ''SIN3A'' gene. Function The protein encoded by this gene is a transcriptional regulatory protein. It contains paired amphipathic helix (PAH) domains, which are important for protein-protein interactions and may mediate repression by the Mad-Max complex. Interactions SIN3A has been shown to interact with: * CABIN1 * HBP1, * HDAC1, * HDAC9, * Histone deacetylase 2, * Host cell factor C1, * IKZF1, * ING1, * KLF11, * MNT, * MXD1, * Methyl-CpG-binding domain protein 2, * Nuclear receptor co-repressor 2, * OGT, * PHF12, * Promyelocytic leukemia protein, * RBBP4, * RBBP7, * SAP130, * SAP30, * SMARCA2, * SMARCA4, * SMARCC1, * SUDS3, * TAL1, and * Zinc finger and BTB domain-containing protein 16. See also * Transcription coregulator In molecular biology and genetics, transcription coregulators are proteins that interact with transcription factors to either activate ...

MAX (gene)
''MAX'' (also known as myc-associated factor X) is a gene that in humans encodes the MAX transcription factor. Function The protein product of ''MAX'' contains the basic helix-loop-helix and leucine zipper motifs. It is therefore included in the bHLHZ family of transcription factors. It is able to form homodimers with other MAX proteins and heterodimers with other transcription factors, including Mad, Mxl1 and Myc. The homodimers and heterodimers compete for a common DNA target site (the E-box) in a gene promoter zone. Rearrangement of dimers (e.g., Mad:Max, Max:Myc) provides a system of transcriptional regulation with greater diversity of gene targets. Max must dimerise in order to be biologically active. Transcriptionally active hetero- and homodimers involving Max can promote cell proliferation as well as apoptosis. Interactions The protein product of Max has been shown to interact with: * Myc, * MNT, * MSH2, * MXD1, * MXI1, * MYCL1, * N-Myc, * SPAG9, * TEAD1, and ...
