Ubiquitin D
Ubiquitin D is a protein that in humans is encoded by the ''UBD'' gene, also known as FAT10. UBD acts like ubiquitin, by covalently modifying proteins and tagging them for destruction in the proteasome. Interactions UBD has been shown to interact with NUB1 and MAD2L1 Mitotic spindle assembly checkpoint protein MAD2A is a protein that in humans is encoded by the ''MAD2L1'' gene. Function MAD2L1 is a component of the mitotic spindle assembly checkpoint that prevents the onset of anaphase until all chromosomes ....

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] |
Ubiquitin
Ubiquitin is a small (8.6 kDa) regulatory protein found in most tissues of eukaryotic organisms, i.e., it is found ''ubiquitously''. It was discovered in 1975 by Gideon Goldstein and further characterized throughout the late 1970s and 1980s. Four genes in the human genome code for ubiquitin: UBB, UBC, UBA52 and RPS27A. The addition of ubiquitin to a substrate protein is called ubiquitylation (or, alternatively, ubiquitination or ubiquitinylation). Ubiquitylation affects proteins in many ways: it can mark them for degradation via the proteasome, alter their cellular location, affect their activity, and promote or prevent protein interactions. Ubiquitylation involves three main steps: activation, conjugation, and ligation, performed by ubiquitin-activating enzymes (E1s), ubiquitin-conjugating enzymes (E2s), and ubiquitin ligases (E3s), respectively. The result of this sequential cascade is to bind ubiquitin to lysine residues on the protein substrate via an isopeptide bond, ...

NUB1
NEDD8 ultimate buster 1 is a protein that in humans is encoded by the ''NUB1'' gene. Function NUB1 interacts with and negatively regulates NEDD8 (MIM 603171), a ubiquitin-like protein that covalently conjugates to cullin (see MIM 603134) family members. upplied by OMIMref name="entrez"/> Interactions NUB1 has been shown to interact with NEDD8, UBD and AIPL1 Aryl-hydrocarbon-interacting protein-like 1 is a protein that in humans is encoded by the ''AIPL1'' gene.

MAD2L1
Mitotic spindle assembly checkpoint protein MAD2A is a protein that in humans is encoded by the ''MAD2L1'' gene. Function MAD2L1 is a component of the mitotic spindle assembly checkpoint that prevents the onset of anaphase until all chromosomes are properly aligned at the metaphase plate. MAD2L1 is related to the MAD2L2 gene located on chromosome 1. A MAD2 pseudogene has been mapped to chromosome 14. Interactions MAD2L1 has been shown to interact with: * ADAM17, * BUB1B, * CDC20, * CDC27 and * Estrogen receptor beta, * MAD2L2, * Mad1 Mad1 is a non-essential protein which in yeast has a function in the spindle assembly checkpoint (SAC).
