Neuron-specific vesicular protein calcyon is a
protein
Proteins are large biomolecules and macromolecules that comprise one or more long chains of amino acid residue (biochemistry), residues. Proteins perform a vast array of functions within organisms, including Enzyme catalysis, catalysing metab ...
that in humans is encoded by the ''CALY''
gene
In biology, the word gene has two meanings. The Mendelian gene is a basic unit of heredity. 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: protei ...
.
Its alternative name is Calcyon.
Function
The protein encoded by this gene is a type II single
transmembrane protein
A transmembrane protein is a type of integral membrane protein that spans the entirety of the cell membrane. Many transmembrane proteins function as gateways to permit the transport of specific substances across the membrane. They frequently un ...
. It is required for maximal stimulated
calcium
Calcium is a chemical element; it has symbol Ca and atomic number 20. As an alkaline earth metal, calcium is a reactive metal that forms a dark oxide-nitride layer when exposed to air. Its physical and chemical properties are most similar to it ...

purinergic or
muscarinic but not
beta-adrenergic receptor
The adrenergic receptors or adrenoceptors are a class of G protein-coupled receptors that are targets of many catecholamines like norepinephrine (noradrenaline) and epinephrine (adrenaline) produced by the body, but also many medications like be ...
s. The encoded protein interacts with
dopamine receptor D1
Dopamine receptor D1, also known as DRD1. It is one of the two types of D1-like receptor family receptors D1 and D5. It is a protein that in humans is encoded by the DRD1 gene.
Tissue distribution
D1 receptors are the most abundant kind of d ...
