The genome of Dehalobacter restrictus - high gene redundancy for a restricted metabolism

Christof Holliger, Julien Maillard, Aamani Rupakula Boyanapalli, Hauke Smidt

Organohalide respiration (OHR) is a bacterial anaerobic respiratory metabolism dedicated to use halogenated compounds as terminal electron acceptors. OHR bacteria are strictly anaerobic microorganisms which use reductive dehalogenases (RdhA) as key enzymes ...

Integrative Genomics Identifies the Corepressor SMRT as a Gatekeeper of Adipogenesis through the Transcription Factors C/EBPβ and KAISO

Bart Deplancke, Sebastian Martin Waszak, Sunil Kumar Raghav, Alina Isakova, Irina Krier

The molecular role of corepressors is poorly understood. Here, we studied the transcriptional function of the corepressor SMRT during terminal adipogenesis. Genome-wide DNA-binding profiling revealed that this corepressor is predominantly located in active ...

Analysis of the Pigment Cell Specific Gene MART-1/Melan-A/mlana

Iraz Toprak Aydin

Pigmentation is a complex process that provides many diverse benefits for the organism. Pigment production takes place in the pigment cell lineage in dedicated organelles called melanosomes. Several proteins are specifically recruited to melanosomes for th ...

Finding sequences that control expression of genes is central to understanding genome function. Previous studies have used evolutionary conservation as an indicator of regulatory potential. Here, we present a method for the unbiased in vivo screen of putat ...

Regulation of DHICA-mediated antioxidation by dopachrome tautomerase: Implication for skin photoprotection against UVA radiation

Friedrich Beermann

Dopachrome tautomerase (Dct) is a critical enzyme in the melanogenesis pathway that isomerizes the intermediate dopachrome to 5,6-dihydroxyindole-2-carboxylic acid (DHICA) and influences the proportion of DHICA monomer incorporated into the 5,6-dihydroxyin ...

Collinear expression of 5′ Hoxd genes during mammalian limb development is required to properly determine digits number and identity. We recently proposed a two-step model to account for the underlying regulatory mechanism, which involves an initial loopin ...

Elsevier Science BV2009

During the course of evolution, many genes that control the development of metazoan body plans were co-opted to exert novel functions, along with the emergence or modification of structures. Gene amplification and/or changes in the cis- regulatory modules ...

Pigment cells of mammals are characterized by two different developmental origins: cells of the retinal pigment epithelium (RPE) originate from the optic cup of the developing forebrain, whereas melanocytes arise from the neural crest. The pigmentation gen ...

Pigment cells of mammals originate from two different lineages: melanocytes arise from the neural crest, whereas cells of the retinal pigment epithelium (RPE) originate from the optic cup of the developing forebrain. Previous studies have suggested that pi ...

Genetics of pigment cells: lessons from the tyrosinase gene family

Friedrich Beermann

In mammals, the melanin pigment is produced in two cell types of distinct developmental origins. The melanocytes of the skin originate form the neural crest whereas the retinal pigment epithelium (RPE) of the eye originates from the optic cup. The genetic ...
