Summary

SEPTIN14 (septin 14, HGNC:33280) is a protein-coding gene on chromosome 7p11.2, encoding Septin-14 (Q6ZU15). Filament-forming cytoskeletal GTPase.

SEPT14 is a member of the highly conserved septin family of GTP-binding cytoskeletal proteins implicated in membrane transport, apoptosis, cell polarity, cell cycle regulation, cytokinesis, and other cellular functions (Peterson et al., 2007 [PubMed 17922164]).

Function. Filament-forming cytoskeletal GTPase. Involved in the migration of cortical neurons and the formation of neuron leading processes during embryonic development. Plays a role in sperm head formation during spermiogenesis, potentially via facilitating localization of ACTN4 to cell filaments.

Subunit / interactions. Septins polymerize into heterooligomeric protein complexes that form filaments, and can associate with cellular membranes, actin filaments and microtubules. GTPase activity is required for filament formation. Interacts with ACTN4. Interacts with SEPTIN9. Interacts (via C-terminus) with SEPTIN4.

Subcellular location. Cytoplasm. Cytoskeleton. Cell projection. Axon. Dendrite. Perikaryon. Perinuclear region. Cytoplasmic vesicle. Secretory vesicle. Acrosome.

Tissue specificity. Testis-specific (at protein level).

Similarity. Belongs to the TRAFAC class TrmE-Era-EngA-EngB-Septin-like GTPase superfamily. Septin GTPase family.
