HOMOLOGY

Homologene

FAMILY

S100-fused protein family

CATEGORY

structural protein

SUBCELLULAR LOCALIZATION	intracellular
	intracellular,cytoplasm,cytoskeleton,intermed filament

basic FUNCTION	aggregating keratin filaments and promoting disulfite-bonding
	integral part of the epidermis that plays a key role in engineering and maintaining the barrier function
	having a key role in maintaining an effective skin barrier against the external environment
	possible genetic modifier in other genodermatoses
	FLG and FLG2 display a related structural organization, an identical pattern of expression and localization in epidermis, and proteolytic processing of a large precursor

Susceptibility

to atopic dermatis, for the extrinsic subtype of AD, and with concomitant respiratory allergic diseases

Variant & Polymorphism other	R510X and 2282del4 are very strong predisposing factors for atopic dermatitis
	four prevalent mutations (R501X, 2282del4, R2447X and S3247X)strongly associated to atopic dermatis
