Post-Translational Dosage Compensation Buffers Genetic Perturbations to Stoichiometry of Protein Complexes. [PDF]
Understanding buffering mechanisms for various perturbations is essential for understanding robustness in cellular systems. Protein-level dosage compensation, which arises when changes in gene copy number do not translate linearly into protein level, is ...

How pleiotropy influences evolution of protein sequence remains unclear. The male-specific lethal (MSL) complex in Drosophila mediates dosage compensation by 2-fold upregulation of the X chromosome in males.

Nuclear Organization and Dosage Compensation [PDF]
Dosage compensation is a strategy to deal with the imbalance of sex chromosomal gene products relative to autosomes and also between the sexes. The mechanisms that ensure dosage compensation for X-chromosome activity have been extensively studied in mammals, worms, and flies.

Targeting of the Dosage-Compensated Male X-Chromosome during Early Drosophila Development
Summary: Dosage compensation, which corrects for the imbalance in X-linked gene expression between XX females and XY males, represents a model for how genes are targeted for coordinated regulation.

The epigenome of evolving Drosophila neo-sex chromosomes: dosage compensation and heterochromatin formation. [PDF]
Sex chromosomes originated from autosomes but have evolved a highly specialized chromatin structure. Drosophila Y chromosomes are composed entirely of silent heterochromatin, while male X chromosomes have highly accessible chromatin and are ...

Dosage Compensation inDrosophila [PDF]
Dosage compensation in Drosophila increases the transcription of genes on the single X chromosome in males to equal that of both X chromosomes in females. Site-specific histone acetylation by the male-specific lethal (MSL) complex is thought to play a fundamental role in the increased transcriptional output of the male X.

The Chromosomal High-Affinity Binding Sites for the Drosophila Dosage Compensation Complex [PDF]
Dosage compensation in male Drosophila relies on the X chromosome-specific recruitment of a chromatin-modifying machinery, the dosage compensation complex (DCC). The principles that assure selective targeting of the DCC are unknown.

Incomplete transcriptional dosage compensation of chicken and platypus sex chromosomes is balanced by post-transcriptional compensation. [PDF]
Heteromorphic sex chromosomes (XY or ZW) present problems of gene dosage imbalance between sexes and with autosomes. A need for dosage compensation has long been thought to be critical in vertebrates.

SU(VAR)3-7 links heterochromatin and dosage compensation in Drosophila. [PDF]
In Drosophila, dosage compensation augments X chromosome-linked transcription in males relative to females. This process is achieved by the Dosage Compensation Complex (DCC), which associates specifically with the male X chromosome.

Pluripotent cells will not dosage compensate [PDF]
Dosage compensation is the mechanism that balances gene expression levels between males and females as well as between the X chromosome and autosomes. In mammals, loss of pluripotency and differentiation are closely linked with the onset of dosage compensation. Pluripotency factors negatively regulate Xist (the non-coding RNA that triggers X chromosome
