HOMOLOGY

FAMILY	RNF144 family
	RING-in-between-RING family of E3 ubiquitin ligases

CATEGORY

enzyme , transcription factor , tumor suppressor

basic FUNCTION	RNF144A, an E3 ubiquitin ligase for DNA-dependent protein kinase catalytic subunit (DNA-PKcs), can promote DNA damage-induced cell apoptosis
	RNF144A may be involved in TP53-mediated apoptosis through down-regulation of DNA-PKcs when cells suffer from persistent or severe DNA damage insults
	RNF144A promotes EGFR ubiquitination, maintains EGFR protein, and prolongs EGF/EGFR signaling during EGF stimulation
	functions as a tumor suppressor in breast cancer
	role for RNF144A in suppression of breast cancer growth and metastasis, and RNF144A is likely the first E3 ubiquitin ligase for HSPA2 in human cancer
	VRK3 protects cells by suppressing oxidative stress-induced ERK, and RNF144A sensitively regulates this process

a component

INTERACTION

DNA

RNA

small molecule

protein	ZDHHC18 and ZDHHC23 competitively interact with a BMI1 E3 ligase, RNF144A, to regulate the polyubiquitination and accumulation of BMI1
	RNF144A interacted with and targeted HSPA2, a putative oncoprotein that is frequently upregulated in human cancer and promotes tumor growth and progression, for ubiquitination and degradation
	under oxidative stress, VRK3 migrates from the nucleus to the cytoplasm, which increases its chance of interacting with RNF144A, thereby promoting the degradation of VRK3

cell & other

REGULATION

induced by

DNA damage that induces RNF144A expression in a TP53-dependent manner

Other
