Rabbit anti-Human Septin 4 Polyclonal Antibody

Uniprot Id

O43236

Target Species

Human

Target Name

SEPT4

Target Full Name

Septin-4

Target Function

Filament-forming cytoskeletal GTPase (Probable). Plays an important role in male fertility and sperm motility. During spermiogenesis, essential for the establishment of the annulus (a fibrous ring structure connecting the midpiece and the principal piece of the sperm flagellum) which is a requisite for the structural and mechanical integrity of the sperm. Involved in the migration of cortical neurons and the formation of neuron leading processes during embryonic development.; Required for the induction of cell death mediated by TGF-beta and possibly by other apoptotic stimuli. Induces apoptosis through binding and inhibition of XIAP resulting in significant reduction in XIAP levels, leading to caspase activation and cell death.

Target Background

This gene is a member of the septin family of nucleotide binding proteins, originally described in yeast as cell division cycle regulatory proteins. Septins are highly conserved in yeast, Drosophila, and mouse, and appear to regulate cytoskeletal organization. Disruption of septin function disturbs cytokinesis and results in large multinucleate or polyploid cells. This gene is highly expressed in brain and heart. Alternatively spliced transcript variants encoding different isoforms have been described for this gene. One of the isoforms (known as ARTS) is distinct; it is localized to the mitochondria, and has a role in apoptosis and cancer.
