PROTEIN

PHYSICAL PROPERTIES

STRUCTURE

motifs/domains	seven homologous repeats of 51-68 AAs, which were later shown to adopt a seven-bladed beta-propeller fold
	beta-propeller domain binds the histone H2A–H2B dimer component of the histone octamer

HOMOLOGY

Homologene

FAMILY

RCC1 superfamily

CATEGORY

regulatory , DNA associated

SUBCELLULAR LOCALIZATION	intracellular
	intracellular,nucleus,chromatin/chromosome
text	predominantly located to nucleus in mitotic cells

basic FUNCTION	functioning as a guanine nucleotide exchange factor for the nuclear Ras-like small G protein, RAN/TC4
	guanine nucleotide exchange factor for the GTPase protein
	catalyses the formation of RanGTP in the nucleus, whereas hydrolysis of RanGTP is stimulated by RANGAP1 and RANBP1 in the cytoplasm
	reads the histone code created by caspase-activated Mst1 to initiate apoptosis by reducing the level of RanGTP in the nucleus
	only known exchange factor for the Ran guanosine triphosphatase and performs essential roles in nuclear transport, spindle organization, and nuclear envelope formation
	minimal essential function of nucleosomes in nuclear pore complexes (NPCs) formation is to recruit RCC1 and AHCTF1

CELLULAR PROCESS	cell cycle, division, mitosis

PHYSIOLOGICAL PROCESS

cellular trafficking transport

text	nucleoplasmic transport
	RAN required for chromatin induced mitotic spindle formation
	nucleus cytoplasmic
	nuclear envelope assembly

PATHWAY

metabolism

signaling

a component

INTERACTION

DNA

RNA

small molecule

protein	histones H2A, H2B docking CHC1 (RCC1) to RAN, enhancer RAN function
	upregulated C-Myc target gene
	interacting with METTL11A, predominant alpha-N-methyltransferase for RCC1
	recruits RAN to nucleosomes and activates RAN nucleotide exchange activity

cell & other	binding to both DNA and histones, and these effects are tail mediated
	binding of RCC1 to the nucleosome is central to the formation of this spatial signal within the nucleus

upregulated by cMyc
