Are there major developmentally regulated H4 gene classes in Xenopus?
Primer extension analysis has been used to study the principal H4 mRNAs present at different developmental stages and in several adult tissues of Xenopus borealis and X. laevis. In X. borealis a single sequence class predominates in oocytes, tadpoles and cultured fibroblasts. There is also a polymorphic minor type which shows no developmental regulation. The primer extension bands obtained from...
متن کاملCAP1 expression is developmentally regulated in Xenopus
We have cloned and characterized a Xenopus member of the cyclase associated protein (CAP) gene family. xCAP1 is expressed as a maternal transcript, but is up-regulated prior to gastrulation and subsequently localizes to head mesenchyme, lens, otic vesicle, and trunk mesoderm including the pronephros. At different stages, the gene also appears to differentiate surface from deep (sensorial) ectod...
متن کاملDevelopmentally regulated expression of a mitogen-activated protein kinase in Xenopus laevis.
Mitogen-activated protein (MAP) kinases are activated in somatic cells in response to many extracellular stimuli and in oocytes during meiotic maturation. We have examined the tissue specificity of expression of a MAP kinase (Xp42) in adult and larval Xenopus laevis. MAP kinase RNA and protein were abundant in the nervous system and lymphoid tissues and were readily detected in most other organ...
متن کاملBiochemical changes in developmentally retarded Xenopus laevis larvae
Premetamorphic tadpoles of Xenopus laevis reared in water containing 001 % propylthiouracil are developmentally retarded and metamorphosis is prevented. When uncrowded, they continue to grow to a giant size. Moderate crowding leads to a slower rate of growth. Thus morphologically premetamorphic tadpoles were produced with lens diameters appropriate to either normal premetamorphic, climactic or ...
متن کاملSequence organization and developmentally regulated transcription of a family of repetitive DNA sequences of Xenopus laevis.
Members of a family of DNA sequences of Xenopus laevis have been cloned and sequenced. Molecular analyses revealed that these sequences are moderately repetitive and dispersed throughout the genome. The sequences of seven clones were compared. Two of the clones lie in the globin gene cluster; one 5' to the adult alpha 1 gene, and the other in the first intron of the tadpole alpha 1 gene. In all...
