HOMOLOGY

Homologene

FAMILY

degenerin/ENaC superfamily of non-voltage-gated, highly amiloride-sensitive cation channels

CATEGORY

transport channel

SUBCELLULAR LOCALIZATION	plasma membrane
text	multi-pass membrane protein

basic FUNCTION	epithelial amiloride-sensitive sodium channel, non-voltage gated, controling the reabsorption of sodium in kidney, colon, lung and sweat glands
	also playing a role in taste perception
	candidate molecule for pH sensing in the gastrointestinal system
	alters proteolytic channel activation and enhances base-line channel activity
	undergoes dynamin-independent endocytosis

CELLULAR PROCESS

PHYSIOLOGICAL PROCESS

active transport

text	Na+ transport

PATHWAY

metabolism

signaling

sensory transduction/taste

a component

component of a heterotetramer including two SCNN1D, one SCNN1B and one SCNN1G

INTERACTION

DNA

RNA

small molecule

protein	COMMD1 associate with SCNN1D and downregulate its activity
	CNKSR3 physically interacts with SCNN1A, B, D, NEDD4L, and SGK1 and stimulates SCNN1A, SCNN1B, SCNN1D function in a PDZ domain-dependent, aldosterone-induced manner

cell & other
