Rabbit anti-Human SPIRE2 Polyclonal Antibody

Uniprot Id

Q8WWL2

Target Species

Human

Target Name

SPIRE2

Target Full Name

Protein spire homolog 2

Target Function

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. Also acts in the nucleus: together with SPIRE1 and SPIRE2, promotes assembly of nuclear actin filaments in response to DNA damage in order to facilitate movement of chromatin and repair factors after DNA damage.

Target Subcellular Location

Target Synonyms

MGC117166; Protein spire homolog 2; Spir-2; SPIR2_HUMAN; Spire homolog 2 (Drosophila); SPIRE2

Target Background

Predicted to enable actin binding activity. Involved in establishment of meiotic spindle localization; formin-nucleated actin cable assembly; and positive regulation of double-strand break repair. Predicted to be located in cytoskeleton; cytosol; and plasma membrane. Predicted to be active in cell cortex and cytoplasmic vesicle membrane. Predicted to colocalize with cleavage furrow.
