Sodium voltage-gated channel alpha subunit 9 (also Na v 1.7) is a sodium ion channel that, in humans, is encoded by the SCN9A gene. [5] [6] [7] It is usually expressed at high levels in two types of neurons: the nociceptive (pain) neurons at the dorsal root ganglion (DRG) and trigeminal ganglion; and sympathetic ganglion neurons, which are part of the autonomic (involuntary) nervous system.
There are also several distinct sodium channel alpha subunit isoforms in skeletal and cardiac muscle (Na v 1.4 [15] and Na v 1.5, [16] respectively). The SCN1A gene codes for the alpha subunit of the voltage-gated sodium ion channel making it a member of ten paralogous gene families which code for the voltage-gated sodium transmembrane proteins ...
Mutations in genes encoding ion channels, which impair channel function, are the most common cause of channelopathies. [1] There are more than 400 genes that encode ion channels, found in all human cell types and are involved in almost all physiological processes. [2] Each type of channel is a multimeric complex of subunits encoded by a number ...
Human somatic variations are somatic mutations (mutations that occur in somatic cells) both at early stages of development and in adult cells. These variations can lead either to pathogenic phenotypes or not, even if their function in healthy conditions is not completely clear yet. [1]
Sam Fife was born in 1925 in Miami, Florida, the son of Samuel Drew Fife, Sr., and Maude Iva Cox. He served in the U.S. Navy in World War II.. He graduated from New Orleans Baptist Theological Seminary in March 1957 and received the Baptism in the Holy Spirit experience while pastoring Bible Baptist Church in the city.
Sodium channel protein type 5 subunit alpha, also known as Na V 1.5 is an integral membrane protein and tetrodotoxin-resistant voltage-gated sodium channel subunit. Na V 1.5 is found primarily in cardiac muscle, where it mediates the fast influx of Na +-ions (I Na) across the cell membrane, resulting in the fast depolarization phase of the cardiac action potential.
The 16 possible mutation types of the substitution class C>A are shown as an example. Once the mutation catalog (e.g. counts for each of the 96 mutation types) of a tumor is obtained, there are two approaches to decipher the contributions of different mutational signatures to tumor genomic landscape:
Potassium voltage-gated channel, Shab-related subfamily, member 1, also known as KCNB1 or K v 2.1, is a protein that, in humans, is encoded by the KCNB1 gene. [ 5 ] [ 6 ] [ 7 ] Potassium voltage-gated channel subfamily B member one, or simply known as KCNB1, is a delayed rectifier and voltage-gated potassium channel found throughout the body.
