FLASH GENE DNA RNA EXPRESSION PROTEIN DISORDER ANIMAL & CELL MODELS

PROTEIN

PHYSICAL PROPERTIES

STRUCTURE

motifs/domains	a N terminal leucine-zipper motif
	a highly basic region
	a VCA domain for activating Arp2/3
	a C terminal VPH (verproline homology)/WH2 (WASP homology 2) domain, binding to LDOC1

HOMOLOGY

Homologene

FAMILY

WAS protein family

CATEGORY

motor/contractile , structural protein

SUBCELLULAR LOCALIZATION	intracellular
	intracellular,cytoplasm,cytoskeleton,microfilament

basic FUNCTION	play a major role in actin polymerization and cytoskeleton organization processes
	a possible involvement in the pathogenesis of neuroblastoma
	playing an important role in cell differentiation and motility
	regulate the remodeling of actin cytoskeleton downstream of Rho GTPases
	thought to be required for lamellipodium and ruffle formation in cells
	coordinate the development of lamellipodia at the leading edges of cells, and loss of its function prevents motility
	activation of WASF3 to promote actin remodeling is enhanced by the ABL-mediated tyrosine phosphorylation of WASF3
	is pivotal in controlling the invasiveness of prostate cancer cells
	required for invasion and metastasis in different cancer cell types

CELLULAR PROCESS	cell organization/biogenesis
	cell communication

PHYSIOLOGICAL PROCESS

text	cell shape and cell cycle control

PATHWAY

metabolism

signaling

a component

associating with the Arp2/3 complex a nucleating core constituent for actin polymerization in vitro

INTERACTION

DNA

RNA

small molecule

protein	dependence of WASF3 on HSP70 and HSP90 chaperone proteins for its function
	HSPA1A stabilizes the WASF3 protein
	is likely protected from proteasome degradation by HSPA1A
	WASF3 is a HIF1A-regulated gene
	novel signaling network whereby JAK2/STAT3 signaling creates a feed-forward loop to raise activated WASF3 levels that promote cancer cell motility
	ATAD3A interacts with the WASF3 metastasis-promoting protein
	stabilization of WASF3 function occurs through its interaction with ATAD3A and HSPA5, which may provide a bridge between the ER and mitochondria, allowing communication between the two organelles

REGULATION

Phosphorylated by

ABL kinase that is essential for its ability to regulate invasion
