CATEGORY

chaperone/stress , structural protein

SUBCELLULAR LOCALIZATION	intracellular
	intracellular,cytoplasm
	intracellular,nucleus

basic FUNCTION	scaffold protein promoting the efficient assembly of the nuclear export complex
	nuclear effector of the RAN pathway
	is a direct export enhancer for beta-catenin, independent of its role as a XPO1-associated nuclear export cofactor
	playing a role in mediating SMAD2/3 nuclear export and terminating TGF-beta signaling
	acts as a XPO1 cofactor, enhancing NES export by stabilizing the export complex in the nucleus

CELLULAR PROCESS

PHYSIOLOGICAL PROCESS

PATHWAY

metabolism

signaling

a component

nuclear export complex

INTERACTION

DNA

RNA

small molecule

protein	linking exportin 1 (XPO1) to the regulator of chromosome condensation 1, CHC1 (RCC1)
	RAN binding
	preferentially bound to importin alpha 3 (KPNA4)
	XPO1-mediated export is regulated by RANBP3, a Ran-interacting nuclear protein
	PPM1A directly interacted with and dephosphorylated RANBP3 at Ser 58
