ANAPC4
Anaphase-promoting complex subunit 4 is an enzyme that in humans is encoded by the ''ANAPC4'' gene. A large protein complex, termed the anaphase-promoting complex (APC), or the cyclosome, promotes metaphase-anaphase transition by ubiquitinating its specific substrates such as mitotic cyclins and anaphase inhibitor, which are subsequently degraded by the 26S proteasome. Biochemical studies have shown that the vertebrate APC contains eight subunits. The composition of the APC is highly conserved in organisms from yeast to humans. The exact function of this gene product is not known. Interactions ANAPC4 has been shown to interact with ANAPC1, ANAPC5, CDC27 and ANAPC7 Anaphase-promoting complex subunit 7 is an enzyme that in humans is encoded by the ''ANAPC7'' gene. Multiple transcript variants encoding different isoforms have been found for this gene. Function This gene encodes a tetratricopeptide repeat c .... References External links * Further reading * ...

ANAPC1
Anaphase-promoting complex subunit 1 is an enzyme that in humans is encoded by the ''ANAPC1'' gene. ANAPC1 is one of at least ten subunits of the anaphase-promoting complex (APC), which functions at the metaphase-to-anaphase transition of the cell cycle and is regulated by spindle checkpoint proteins. The APC is an E3 ubiquitin ligase that targets cell cycle regulatory proteins for degradation by the proteasome, thereby allowing progression through the cell cycle (supplied by OMIM). Interactions ANAPC1 has been shown to interact with ANAPC5, ANAPC4, ANAPC2, CDC27 and ANAPC7 Anaphase-promoting complex subunit 7 is an enzyme that in humans is encoded by the ''ANAPC7'' gene. Multiple transcript variants encoding different isoforms have been found for this gene. Function This gene encodes a tetratricopeptide repeat c ....

ANAPC5
Anaphase-promoting complex subunit 5 is an enzyme that in humans is encoded by the ''ANAPC5'' gene. The anaphase-promoting complex (APC) consists of at least 8 protein subunits, including APC5, CDC27 (APC3; MIM 116946), CDC16 (APC6; MIM 603461), and CDC23 (APC8; MIM 603462). upplied by OMIMref name="entrez" /> Interactions ANAPC5 has been shown to interact with ANAPC1, ANAPC4, CDC27 and PABPC1 Polyadenylate-binding protein 1 is a protein that in humans is encoded by the ''PABPC1'' gene.

CDC27
Cell division cycle protein 27 homolog is a protein that in humans is encoded by the ''CDC27'' gene. Function The protein encoded by this gene shares strong similarity with Saccharomyces cerevisiae protein Cdc27, and the gene product of Schizosaccharomyces pombe nuc 2. This protein is a component of anaphase-promoting complex (APC), which is composed of eight protein subunits and highly conserved in eucaryotic cells. APC catalyzes the formation of cyclin B-ubiquitin conjugate that is responsible for the ubiquitin-mediated proteolysis of B-type cyclins. This protein and 3 other members of the APC complex contain the TPR (tetratricopeptide repeat), a protein domain important for protein-protein interaction. This protein was shown to interact with mitotic checkpoint proteins including Mad2, p55CDC and BUBR1, and thus may be involved in controlling the timing of mitosis. Interactions CDC27 has been shown to interact with: * ANAPC10, * ANAPC11, * ANAPC1, * ANAPC4, * ANAPC5 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Enzyme
Enzymes () are proteins that act as biological catalysts by accelerating chemical reactions. The molecules upon which enzymes may act are called substrates, and the enzyme converts the substrates into different molecules known as products. Almost all metabolic processes in the cell need enzyme catalysis in order to occur at rates fast enough to sustain life. Metabolic pathways depend upon enzymes to catalyze individual steps. The study of enzymes is called ''enzymology'' and the field of pseudoenzyme analysis recognizes that during evolution, some enzymes have lost the ability to carry out biological catalysis, which is often reflected in their amino acid sequences and unusual 'pseudocatalytic' properties. Enzymes are known to catalyze more than 5,000 biochemical reaction types. Other biocatalysts are catalytic RNA molecules, called ribozymes. Enzymes' specificity comes from their unique three-dimensional structures. Like all catalysts, enzymes increase the reaction ra ...

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] |
PNAS
''Proceedings of the National Academy of Sciences of the United States of America'' (often abbreviated ''PNAS'' or ''PNAS USA'') is a peer-reviewed multidisciplinary scientific journal. It is the official journal of the National Academy of Sciences, published since 1915, and publishes original research, scientific reviews, commentaries, and letters. According to ''Journal Citation Reports'', the journal has a 2021 impact factor of 12.779. ''PNAS'' is the second most cited scientific journal, with more than 1.9 million cumulative citations from 2008 to 2018. In the mass media, ''PNAS'' has been described variously as "prestigious", "sedate", "renowned" and "high impact". ''PNAS'' is a delayed open access journal, with an embargo period of six months that can be bypassed for an author fee ( hybrid open access). Since September 2017, open access articles are published under a Creative Commons license. Since January 2019, ''PNAS'' has been online-only, although print issues are ava ...
