Testis-specific spindle-associated factor that plays a role in spermatogenesis. In association with HSPA2, participates in the maintenance of spindle integrity during meiosis in male germ cells.
Subcellular locations: Cytoplasm, Cytoskeleton, Spindle
Colocalizes with alpha tubulin during meiosis. Colocalizes with HSPA2 at spindle during the meiosis process.
Expressed in spermatocytes and elongating spermatids inside the seminiferous tubules (at protein level) . Testis-specific (, ).
