Molecular cloning of flounder Xp18, a newly identified highly conserved protein mainly expressed in the ovary ArchiMer
Cachot, Jerome; Bultelle, Florence; Drouot, Laurent; Galgani, Francois; Frebourg, Thierry; Leboulenger, François; Danger, Jean-michel.
Screening of a flounder ovary cDNA library with a rainbow trout p53 probe led to the isolation of a p53-unrelated cDNA encoding an unknown 161 amino acid protein. In view of its apparent molecular weight and yet unknown function, the deduced protein was named Xp18. Corresponding orthologous cDNAs or expressed sequence tags have been identified in several species including human, rodents, bovine, chicken and zebrafish and a related cDNA has also been isolated in the fruit fly. Deduced amino acid sequences appeared to be extremely well conserved throughout vertebrate evolution. Structure predictions suggested that Xp 18 may correspond to an integral protein comprising four transmembrane domains. The charged C-termini of all known vertebrate Xp18-like...

Mutation rate of 7 X-STRs of common use in population genetics JBAG
Glesmann,Laura A.; Martina,Pablo F.; Vidal Rioja,Lidia; Catanesi,Cecilia I..
Microsatellite loci analysis is a relevant tool in population genetic studies and also in paternity testing. In this field the X-chromosome STR loci are widely used for female offspring testing but their mutation rates are scarcely known. In this work we performed a mutation rate analysis of seven STR markers located in the X- chromosome specific region, in mother-son pairs and father-mother-daughter trios. Among 1015 allele transfers, we found only one change for a mother-daughter transmission in the DXS9898 locus, consisting of a loss of one single repeat. This finding allowed us to estimate a general mutation rate of μ=9.85 x 10-4 (2.49 x 10-4 - 5.49 x 10-2) which can be applied to population studies. This value is consistent with other reports...
