HOMOLOGY

intraspecies

homolog to desmoglein DGIV/DGV

Homologene

FAMILY

desmosomal cadherin family of cell-cell adhesion molecules

CATEGORY

adhesion

SUBCELLULAR LOCALIZATION	plasma membrane,junction,gap
	plasma membrane,junction,desmosome

basic FUNCTION	required for cell adhesion and desmosome formation
	desmosomal cadherins exhibiting differentiation-specific patterns of expression in the epidermis
	transmembrane glycoprotein specifically synthesized in the inner root sheath of hair follicle and in the companion layer
	promotes the formation of intercellular adhesion complexes and the relative level of DSG1 and DSC1 expressed at the cell surface regulates this adhesive process
	play a critical role in the maintenance of tissue integrity in epithelia and cardiac muscle

CELLULAR PROCESS

cell communication

PHYSIOLOGICAL PROCESS

PATHWAY

metabolism

signaling

a component	compoenent of desmosome
	essential constituents of desmosomes, intercellular junctions

INTERACTION

DNA

RNA

small molecule

protein

plakoglobin, but normally not CTNNB1, is also a structural constituent of desmosomes, where it binds to the cytoplasmic domains of the desmosomal cadherins, desmogleins and desmocollins

cell & other

REGULATION

activated by

C/EBPalpha but not C/EBPbeta (differentially regulated by C/EBP (CCAAT/enhancer-binding protein) family members)

ASSOCIATED DISORDERS

corresponding disease(s)

Other morbid association(s)

Type Gene Modification Chromosome rearrangement Protein expression Protein Function constitutional     --low   with DSC1, were dramatically reduced in the upper most living layers of the epidermis in Netherton syndrome tumoral     --other   de novo expression in colorectal cancer

Susceptibility

to Alzheimer disease

Variant & Polymorphism other	polymorphism modulating AD susceptibility in a gender-specific manner
