CENPT
Centromere protein T is a protein that in humans is encoded by the ''CENPT'' gene. Clinical significance Mutations in ''CENPT'' cause an autosomal recessive syndrome of microcephaly, short stature, skeletal abnormalities, underdeveloped genitalia and pubertal delay.

CENPE
Centromere-associated protein E is a protein that in humans is encoded by the ''CENPE'' gene. Centromere-associated protein E is a kinesin-like motor protein that accumulates in the G2 phase of the cell cycle. Unlike other centromere-associated proteins, it is not present during interphase and first appears at the centromere region of chromosomes during prometaphase. CENPE is proposed to be one of the motors responsible for mammalian chromosome movement and/or spindle elongation. Clinical significance Mutations in ''CENPE'' result in autosomal recessive primary microcephaly type 13, which includes skeletal abnormalities and immunodeficiency.

CENPF
Centromere protein F is a protein that in humans is encoded by the ''CENPF'' gene. It is involved in chromosome segregation during cell division. It also has a role in the orientation of microtubules to form cellular cilia. Function CENPF is part of the nuclear matrix during the G2 phase of the cell cycle (the phase of rapid protein synthesis in preparation for mitosis). In late G2, the protein forms part of the kinetochore, a disc-shaped protein complex that allows the centromere of two sister chromatids to attach to microtubules (forming the spindle apparatus) in order for the microtubules to pull them apart in the process of dividing the cell. It remains part of the kinetochore through early anaphase (the chromosome-dividing phase). In late anaphase, CENPF localises to the spindle midzone, and in telophase (the cell-dividing phase) it localises to the intercellular bridge. It is thought to be subsequently degraded. Mutations in ''CENPF'' lead to impaired cell division during ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 resid ...

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 g ...
