Enkurin
Enkurin is a protein that in humans is encoded by the ''ENKUR'' gene. Enkurin interacts with transient receptor potential canonical (TRPC) cation channels (e.g., TRPC1) and functions as an adaptor protein, tethering signal transduction Signal transduction is the process by which a chemical or physical signal is transmitted through a cell as a series of molecular events, most commonly protein phosphorylation catalyzed by protein kinases, which ultimately results in a cellular ... proteins to TRPC channels.

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 ...

TRPC
TRPC is a family of transient receptor potential cation channels in animals. TRPC channels form the subfamily of channels in humans most closely related to drosophila TRP channels. Structurally, members of this family possess a number of similar characteristics, including 3 or 4 ankyrin repeats near the N-terminus and a TRP box motif containing the invariant EWKFAR sequence at the proximal C-terminus. These channels are non-selectively permeable to cations, with a prevalence of calcium over sodium variable among the different members. Many of TRPC channel subunits are able to coassemble. The predominant TRPC channels in the mammalian brain are the TRPC 1,4 and 5 and they are densely expressed in corticolimbic brain regions, like the hippocampus, prefrontal cortex and lateral septum. These 3 channels are activated by the metabotropic glutamate receptor 1 agonist dihydroxyphenylglycine. In general, TRPC channels can be activated by phospholipase C stimulation, with some me ...

TRPC1
Transient receptor potential canonical 1 (TRPC1) is a protein that in humans is encoded by the ''TRPC1'' gene. Function TRPC1 is an ion channel located on the plasma membrane of numerous human and animal cell types. It is a nonspecific cation channel, which means that both sodium and calcium ions can pass through it. TRPC1 is thought to mediate calcium entry in response to depletion of endoplasmic calcium stores or activation of receptors coupled to the phospholipase C system. In HEK293 cells the unitary current-voltage relationship of endogenous TRPC1 channels is almost linear, with a slope conductance of about 17 pS. The extrapolated reversal potential of TRPC1 channels is +30 mV. The TRPC1 protein is widely expressed throughout the mammalian brain and has a similar corticolimbic expression pattern as TRPC4 and TRPC5. The highest density of TRPC1 protein is found in the lateral septum, an area with dense TRPC4 expression, and hippocampus and prefrontal cortex, areas with de ...

Signal Transducing Adaptor Protein
Signal transducing adaptor proteins (STAPs) are proteins that are accessory to main proteins in a signal transduction pathway. Adaptor proteins contain a variety of protein-binding modules that link protein-binding partners together and facilitate the creation of larger signaling complexes. These proteins tend to lack any intrinsic enzymatic activity themselves, instead mediating specific protein–protein interactions that drive the formation of protein complexes. Examples of adaptor proteins include MYD88, Grb2 and SHC1. Signaling components Much of the specificity of signal transduction depends on the recruitment of several signalling components such as protein kinases and G-protein GTPases into short-lived active complexes in response to an activating signal such as a growth factor binding to its receptor. Domains Adaptor proteins usually contain several domains within their structure (e.g., Src homology 2 (SH2) and SH3 domains) that allow specific interactions with se ...
