Gene Summary

meiosis I arrest (mia) encodes a paralog of the generally expressed TBP-associated factor encoded by Taf6. mia is expressed only in differentiating male germ cells, starting in the spermatocyte stage. Along with four other testis-specific TBP-associated factors, the product of mia is required for full levels of transcript production from multiple genes expressed in primary spermatocytes in preparation for meiotic cell cycle progression and spermatid differentiation.

TESTIS-SPECIFIC TBP-ASSOCIATED FACTORS -: Testis-specific TBP-associated factors (tTAFs) are paralogs of the generally expressed TAF subunits of transcription factor IID (TFIID). They are predominantly localized to spermatocyte nucleoli and regulate the transcription of genes necessary for spermatocyte entry into meiosis. (Adapted from FBrf0200958).

can, mia and sa are required for accumulation of twe^T:Ecol\lacZ transgene in late primary spermatocytes.

(White-Cooper et al., 1998)

Wild type function of aly, can, mia and sa is required for cell-cycle progression through the G₂/M transition of meiosis I in males and for onset of spermatid differentiation. The phenotype of these meiotic arrest mutants is strikingly similar to the histopathological features of meiosis I maturation arrest infertility in human males, suggesting that the control point may be conserved from flies to man.

(Lin et al., 1996)

mia is required for both the progression of the male meiotic cell cycle and the onset of postmeiotic differentiation.

(Lin et al., 1995)

Mutations in mia cause a complete arrest of spermatogenesis at the G2/M transition to meiosis I, similar to aly, can, and sa.
