Differentially regulated and evolved genes in the fully sequenced Xq/Yq pseudoautosomal region.
Human sex chromosomes, which are morphologically and genetically different, share few regions of homology. Among them, only pseudoautosomal regions (PARs) pair and recombine during meiosis. To better address the complex biology of these regions, we sequenced the telomeric 400 kb of the long arm of the human X chromosome, including 330 kb of the human Xq/YqPAR and the telomere. Sequencing reveal...
متن کاملA major recombination hotspot in the XqYq pseudoautosomal region gives new insight into processing of human gene conversion events.
Recombination plays a fundamental role in meiosis. Non-exchange gene conversion (non-crossover, NCO) may facilitate homologue pairing, while reciprocal crossover (CO) physically connects homologues so they orientate appropriately on the meiotic spindle. In males, X-Y homologous pairing and exchange occurs within the two pseudoautosomal regions (PARs) together comprising <5% of the human sex chr...
متن کاملThe Eutherian Pseudoautosomal Region.
The pseudoautosomal region (PAR) is a unique segment of sequence homology between differentiated sex chromosomes where recombination occurs during meiosis. Molecular and functional properties of the PAR are distinctive from the autosomes and the remaining regions of the sex chromosomes. These include a higher rate of recombination than genome average, bias towards GC-substitutions and increased...

15 صفحه اولPseudoautosomal genes in man.
MIC2, which encodes the 12E7 antigen, is the only well-defined pseudoautosomal gene in man. We have isolated cDNA and genomic sequences corresponding to MIC2 and have produced monoclonal antibodies reacting with the 12E7 antigen. These molecular tools have been used to investigate the genetics and biochemistry of the MIC2 system. Recent results suggest that MIC2 is the most proximal of the curr...
