Dosage compensation is an essential process that equalizes transcript levels of X-linked genes between sexes by forming a domain of coordinated gene expression. Throughout the evolution of Diptera, many different X-chromosomes acquired the ability to be dosage compensated. Once each newly evolved X-chromosome is targeted for dosage compensation in XY males, its active genes are upregulated two-...
Dosage compensation--equalizing gene expression levels in response to differences in gene dose or copy number--is classically considered to play a critical role in the evolution of heteromorphic sex chromosomes. As the X and Y diverge through degradation and gene loss on the Y (or the W in female-heterogametic ZW taxa), it is expected that dosage compensation will evolve to correct for sex-spec...
The suppressor of Hairy-wing [su(Hw)] gene encodes a zinc finger protein that binds to a repeated motif in the gypsy retrotransposon. These DNA sequences, called the su(Hw)binding region, have properties of an insulator region because they (1) disrupt enhancer/silencer function in a position-dependent manner and (2) protect the mini-white gene from both euchromatic and heterochromatic position ...
