CC   -!- FUNCTION: Unknown. In males lacking the Y chromosome, its strong
CC       overexpression leads to the appearance of proteinaceous star-shaped
CC       crystals in the primary spermatocytes causing meiotic drive, possibly
CC       by interfering with normal casein kinase 2 activity.
CC   -!- SUBUNIT: Interacts in vitro with the casein kinase 2 alpha subunit
CC       (CkII-alpha). The relevance of such interaction is however unclear in
CC       vivo. {ECO:0000269|PubMed:7597082}.
CC   -!- TISSUE SPECIFICITY: Probably not expressed in wild-type flies. In males
CC       lacking the Y chromosome, it is testis-specific and constitutes the
CC       main component of star-shaped crystals. {ECO:0000269|PubMed:7597082}.
CC   -!- INDUCTION: In wild-type flies, it is strongly down-regulated by double-
CC       stranded RNA (dsRNA) interference mediated by Su(Ste) transcripts. In
CC       males lacking the Y chromosome, the absence of Su(Ste) locus, relieves
CC       such down-regulation, explaining why it is strongly expressed.
CC       {ECO:0000269|PubMed:11470406, ECO:0000269|PubMed:11513298}.
CC   -!- MISCELLANEOUS: There are multiple copies of the stellate gene in fruit
CC       fly, encoding proteins that are extremely similar, which makes their
CC       individual characterization difficult. Thus, most experiments probably
CC       do not discriminate between the different members.
CC   -!- SIMILARITY: Belongs to the casein kinase 2 subunit beta family.
CC       {ECO:0000305}.
