Abstract:
We have identified a localized RNA component of Xenopus germ plasm. This RNA, Xdazl (Xenopus DAZ-like), encodes a protein homologous to human DAZ (Deleted in Azoospermia), vertebrate DAZL and Drosophila Boule proteins. Human males deficient in DAZ have few or no sperm and boule mutant flies exhibit complete azoospermia and male sterility. Xdazl RNA was detected in the mitochondrial cloud and vegetal cortex of oocytes. In early embryos, the RNA was localized exclusively in the germ plasm. Consistent with other organisms, Xdazl RNA was also expressed in the spermatogonia and spermatocytes of fro

Abstract:
The proper expression of a gene to a protein is a complicated process with many steps. One of the major steps is translation, the process of decoding a messenger RNA signal and the building of a protein from its component parts. The control of translation is one of the major steps for the overall control of gene expression and its dysregulation is associated with a wide variety of human diseases including neurological, metabolic and reproductive disorders. Dazl family proteins are germ cell restricted RNA binding proteins that contain a motif characteristic of this family, the DAZ domain. Whil

Abstract:
Gametogenesis is a highly complex process that requires stringent control of gene expression, in which translational regulation plays an essential role. Deleted in Azoospermia-like (DAZL) belongs to the DAZ family of RNA-binding proteins, which are restricted to germ cells, and regulate mRNA translation. Importantly, loss of function of these proteins results in infertility in both males and females in a wide variety of organisms. A model for the mechanism by which DAZL stimulates translation has been proposed based on work in Xenopus laevis (X. laevis) oocytes. In this model, DAZL functions b

Abstract:
A number of genes have been associated with variation in human spermatogenesis related to fertility. One of these, the Deleted in Azoospermia (DAZ) gene, exists as copies on two chromosomes, 3 and Y. The autosomal copy, DAZ-like (DAZL), has one RNA recognition motif (RRM) and is homologous to the DAZL gene found throughout the vertebrate lineage. There are four copies of DAZ on the Y chromosome with a pair at each of two sites. One pair contains a single RRM and the other has three RRMs. Human DAZ is homologous to genes in old world primates and ape Y chromosomes. Both DAZ and DAZL bind messen

The azoospermia factor c (AZFc) region of the human Y chromosome consists entirely of very long repeats and is prone to rearrangement. This region is frequently deleted in infertile men with non-obstructive azoospermia or severe oligospermia.

Abstract Following one of the three strategies described in this section, from a single targeting construct, ES clones can be generated which harbor either a loxP-flanked (floxed) allele suitable for conditional gene targeting or which contain the final genetic modification resulting from ere-mediated deletion or inversion. For the floxed allele subsequent ere-mediated recombination will result in gene inactivation or modification, depending on loxP positioning and orientation. The mice derived from ES cells with a floxed allele can be crossed to ere transgenic mice for conditional gene modifi
