PROTEIN

PHYSICAL PROPERTIES

STRUCTURE

motifs/domains

a Cyclin F-binding motif, in a region of RRM2 located between amino acids 40-65, containing two putative CY motifs

HOMOLOGY

interspecies

homolog to murine Rrm2

Homologene

FAMILY

ribonucleoside diphosphate reductase small chain family

CATEGORY

enzyme

SUBCELLULAR LOCALIZATION	intracellular
	intracellular,cytoplasm
text	is largely cytoplasmic
	its expression is S phase-specific and required for DNA replication

basic FUNCTION	ribonucleoside diphosphate reductase activity
	promoter responsible for cell-cycle specific expression
	plays an active role in tumor progression
	its activity is a prosurvival function inactivated by proteolysis during apoptosis
	plays a significant role in the regulation of cell invasiveness, cell migration and tumor metastasis

CELLULAR PROCESS

nucleotide, replication

PHYSIOLOGICAL PROCESS

PATHWAY

metabolism

purine/pyrimidine

signaling

pyrimidine biosynthetic pathway

a component

component of the ribonucleotide reductase

INTERACTION

DNA

RNA

small molecule	metal binding,
	binding two iron ions

protein	heterodimerizing with RRM1
	positive role of RRM2 in tumor angiogenesis and growth through regulation of the expression of THBS1 and VEGFA
	is a new interactor of the F-box protein CCNF
	Cyclin F directly controls the ubiquitin-mediated degradation of RRM2
	RRM2 regulates BCL2 protein stability, with RRM2 suppression leading to increased BCL2 degradation, and critical link between RRM2 and BCL2 in apoptosis signaling
	E2F1 can promote colorectal cancer proliferation, migration, invasion and metastasis by regulating RRM2 transactivation
	CDKL3 is a promotor for glioma, probably through the regulation of RRM2 and activation of the JNK signalling pathway
