PKD2L1
Polycystic kidney disease 2-like 1 protein also known as transient receptor potential polycystic 2 (TRPP2; formerly TRPP3) is a protein that in humans is encoded by the ''PKD2L1'' gene. Function TRPP2 is a member of the polycystin protein family. TRPP2 contains multiple transmembrane domains, and cytoplasmic N- and C-termini. TRPP2 may be an integral membrane protein involved in cell-cell/matrix interactions. TRPP2 functions as a calcium-regulated nonselective cation channel. Alternative splice variants have been described but their full length sequences have not been determined. Interactions PKD2L1 has been shown to interact with TNNI3. See also * TRPP TRPP (transient receptor potential polycystic) is a family of transient receptor potential ion channels which when mutated can cause polycystic kidney disease. Subcategories TRPP subunits can be divided into two subcategories depending on structu ... References Further reading * * * * * * * * * * * * * { ...

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] |
TNNI3
Troponin I, cardiac muscle is a protein that in humans is encoded by the ''TNNI3'' gene. It is a tissue-specific subtype of troponin I, which in turn is a part of the troponin complex image:Troponin Ribbon Diagram.png, 400px, Ribbon representation of the human cardiac troponin core complex (52 kDa core) in the calcium-saturated form. Blue = troponin C; green = troponin I; magenta = troponin T.; ; rendered with PyMOL Troponin, .... The ''TNNI3'' gene encoding cardiac troponin I (cTnI) is located at 19q13.4 in the human chromosomal genome. Human cTnI is a 24 kDa protein consisting of 210 amino acids with isoelectric point (pI) of 9.87. cTnI is exclusively expressed in adult cardiac muscle. Gene evolution left, Figure 1: A phylogenetic tree is derived from alignment of amino acid sequences. cTnI has diverged from the skeletal muscle isoforms of TnI (slow TnI and fast TnI) mainly with a unique N-terminal extension. The amino acid sequence of cTnI is strongly conserved among ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
