Evidence for the activation of Src family PTK in the bud to determine whether the increase in P above Tyr-containing proteins K Nnten BMS-554417 lead to localized activation of Src family PTK, we used an antique Body phosphorylation site specific for detecting activated Src family members in the egg by immunofluorescence. Clone 28-Antique Body recogn t the dephosphorylated C-terminal tyrosine, and flanking sequence, the plurality of the Src family PTK. This antique Body recognizes Src, Fyn, activated and perhaps other members of the Src family and we have recently used activated Src family PTK detected in zebrafish egg. The specificity Antique this Body in the mouse egg system was determined by Western blot analysis shows MII oocytes showed that the clone 28-Antique Body bound to a single band of 60 kDa and 59 binding was blocked by excess peptide epitope.
Immunofluorescence analysis of mouse oocytes at different times before and after fertilization shown that Src family PTK activated gleichf RMIG into the cytoplasm of oocytes and zygotes were beginning MII distributed. Trichostatin A In sharp contrast with the P marking Tyr clone suspended 28-binding to any significant concentrations in the egg cortex. However, the meiotic spindle strongly Heren by clone 28-antique Body in all of the eggs than in h Mag was BEP influenced the apparent t. 7B. The position of the Src family PTKs to the results of a recent report in which a monoclonal has antique Directed against the body of PTK autophosphorylation Srcfamily the pen in mouse oocytes pin.
We repeated the results and it is clear that the clone 28-antique Srcantibody Nonphospho body and pin with a label Hnlichen morphology. Since the antique Body binds to Src kinases Nonphospho inactive Src family, the result shown in Figure 7B, C show that the spindle with a population of PTK Src family kinases, which is both active and inactive comprises assigned. Since the development of the zygote progressed, the distribution of clone 28 marking not in anaphase II, telophase and the pronuclear was ver Changed. The Bindungsspezifit t of clone 28 spindle was demonstrated by incubation of the antique Rpers with a blocking peptide duplicating the epitope against which the antique Body has been developed. Once this is complete meiosis and pronuclear zygotes end, the clone 28-antique Found body, the pronukle Mark out cover.
In cleavage stage mouse embryos activated Src family PTK was still with the nuclear envelope 2 cells from the embryo are brought together, although labeling was less intense than pronuclear. Written embryos st in the process of mitotic division gel PTK Srcfamily activated with the mitotic spindle and Mittelk Rperstruktur assigned. Compaction is the Src family PTKs are activated no longer associated with the nuclear envelope and the bark remained free of Src family PTK activity t. Blastocyst stage embryos were also activated Src family PTK with mitotic spindles and midbodies connected. Beyond the blastocyst was the first stage of development, will be concentrated in the active Src family PTKs in the cortical cytoplasm of single cells. It was the largest human-run in the inner cell mass, but also visible in the
