CATEGORY

structural protein

SUBCELLULAR LOCALIZATION	intracellular
	intracellular,cytoplasm,cytoskeleton,intermed filament

basic FUNCTION	calcium binding protein of differentiated hard keratinizing tissues
	intermediate filament-associated protein (IFAP)
	plays a key role in the assembly of keratin intermediate filaments (IFs) during the hair cycle
	is a potential major autoantigen in human alopecia areata
	large structural protein abundant in the inner root sheath (IRS) of anagenic hair follicles, which has been thought to mediate the keratin filamentous assembly
	latches onto the keratin bundles by its C-terminus and rearranges the keratin meshwork by intrinsic cohesive activity for the granule formation

a component

component of the epidermal differentiation complex (EDC@)

INTERACTION

DNA

RNA

small molecule

protein

BMP4 facilitates TCHH transcription, and intriguingly, a nuclear lamina component plays a key role in the posttranslational stabilization of TCHH protein
