The 5 function of WH2 of the protein

S.NOUniprot IDProtein Name Sequence LengthWH2 Repeated RegionFunction
1 O75128 Protein cordon-bleu1261Plays an important role in the reorganization of the actin cytoskeleton.
Regulates neuron morphogenesis and increases branching of axons and dendrites.
Regulates dendrite branching in Purkinje cells (By similarity).
Binds to and sequesters actin monomers (G actin).
Nucleates actin polymerization by assembling three actin monomers in cross-filament orientation and thereby promotes growth of actin filaments at the barbed end.
Can also mediate actin depolymerization at barbed ends and severing of actin filaments.
Promotes formation of cell ruffles.
2 Q8WWL2 Protein spire homolog 2 714"Acts as an actin nucleation factor, remains associated with the slow-growing pointed end of the new filament.
Involved in intracellular vesicle transport along actin fibers, providing a novel link between actin cytoskeleton dynamics and intracellular transport.
Required for asymmetric spindle positioning and asymmetric cell division during meiosis.
Required for normal formation of the cleavage furrow and for polar body extrusion during female germ cell meiosis".
3 O00401 Neural Wiskott-Aldrich syndrome protein 505"Regulates actin polymerization by stimulating the actin-nucleating activity of the Arp2/3 complex.
Involved in mitosis and cytokinesis, via its role in the regulation of actin polymerization.
Binds to HSF1/HSTF1 and forms a complex on heat shock promoter elements (HSE) that negatively regulates HSP90 expression.
Plays a role in dendrite spine morphogenesis (By similarity)".
4 Q08AE8 Protein spire homolog 1 756"Acts as an actin nucleation factor, remains associated with the slow-growing pointed end of the new filament.
Involved in intracellular vesicle transport along actin fibers, providing a novel link between actin cytoskeleton dynamics and intracellular transport.
Required for asymmetric spindle positioning and asymmetric cell division during meiosis.
Required for normal formation of the cleavage furrow and for polar body extrusion during female germ cell meiosis".
5 Q8TF30 "WASP homolog-associated protein with actin, membranes and microtubules "809Acts as a nucleation-promoting factor (NPF) that stimulates Arp2/3-mediated actin polymerization both at the Golgi apparatus and along tubular membranes.
Its activity in membrane tubulation requires F-actin and interaction with microtubules.
Proposed to use coordinated actin-nucleating and microtubule-binding activities of distinct WHAMM molecules to drive membrane tubule elongation; when MT-bound can recruit and remodel membrane vesicles but is prevented to activate the Arp2/3 complex.
Involved as a regulator of Golgi positioning and morphology.
Participates in vesicle transport between the reticulum endoplasmic and the Golgi complex.
Required for RhoD-dependent actin reorganization such as in cell adhesion and cell migration.
