SUBCELLULAR LOCALIZATION	plasma membrane
	intracellular
	intracellular,cytoplasm,cytosolic
	intracellular,cytoplasm,cytoskeleton,microtubule,mitotic spindle
	intracellular,nucleus,nucleoplasm
text	associates with mitotic spindles and is crucial for proper spindle assembly and mitotic progression

basic FUNCTION	regulates tubular absorption of sodium by modulating the expression levels of the sodium-potassium-ATPase in renal tubular cells
	calmodulin binding protein
	actin-binding proteins located at the spectrin-actin junctions, also called the junctional complex, in the erythrocyte membrane
	can have a role in modulating the transcriptional regulating activity of RFX1
	play an essential role in the maintenance of erythrocyte shape and membrane stability
	forms a bridge between the erythrocyte membrane and its cytoskeleton and regulates membrane cohesion
	roles for adducins in stabilization of epithelial junctions and regulation of junctional remodeling
	role for ADD1 in memory
	is an actin-binding protein that has been shown to play important roles in the stabilization of the membrane cortical cytoskeleton and cell-cell adhesions
	protein organizing the cortical actin cytoskeleton and a target of RHOA and PRKC signaling
	novel function of ADD1 in maintaining spindle pole integrity through its interaction with TPX2

constituent of the erythrocyte membrane skeleton

INTERACTION

DNA

RNA

small molecule

protein	interaction with ACE not only on blood pressure regulation but also on the progression of renal dysfunction in patients with IgA nephropathy
	interaction with regulatory factor for X box (RFX1), a nuclear protein that down regulates the expression of several proteins in non neuronal cells
	binds directly to p55 and glycophorin C, a transmembrane protein, and this ternary complex is believed to attach the junctional complex to the plasma membrane
	binding to SLC2A1 (with dematin form a ternary complex that resists biochemical dissociation upon detergent extraction of the erythrocyte ghosts)
	novel function for ADD1 in mitotic spindle assembly through its interaction with MYO10
	regulation of desmosomal adhesion by RHOA- and PRKC-mediated ADD1 phosphorylation in keratinocytes
	ZNF322 positively regulates transcription of alpha-adducin (ADD1) and cyclin D1 (CCND1) to promote tumorgenicity of lung cancer
