Alpha-2C adrenergic receptor

The alpha-2C adrenergic receptor (α2C adrenoceptor), also known as ADRA2C, is an is_associated_with::alpha-2 adrenergic receptor, and also denotes the human is_associated_with::gene encoding it.

Receptor
Alpha-2-adrenergic receptors include 3 highly homologous subtypes: alpha2A, alpha2B, and alpha2C. These receptors have a critical role in regulating is_associated_with::neurotransmitter release from is_associated_with::sympathetic nerves and from adrenergic neurons in the is_associated_with::central nervous system. Studies in mice revealed that both the alpha2A and alpha2C subtypes were required for normal is_associated_with::presynaptic control of transmitter release from sympathetic nerves in the is_associated_with::heart and from central noradrenergic neurons; the alpha2A subtype inhibited transmitter release at high stimulation frequencies, whereas the alpha2C subtype modulated neurotransmission at lower levels of nerve activity.

Gene
This gene encodes the alpha2C subtype, which contains no is_associated_with::introns in either its coding or is_associated_with::untranslated sequences.
