CC   -!- FUNCTION: Possible structural role in the sperm tail. It is associated
CC       with axonemal structures.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000250}.
CC   -!- TISSUE SPECIFICITY: Testis. Located in spermatocytes and spermatid
CC       bundles.
CC   -!- DOMAIN: The predominant structure is alpha-helical.
CC   -!- POLYMORPHISM: The number of repeats varies between strains.
