... 2004 protein. We set out to address this question by use of the SH2 domain of Grb4 and the PDZ domain of the RGS3 protein. We titrated the SH2 protein into the fluorescein- labeled ephrinB2(301–333)-pY304 ... 1. The effect of tyrosine phosphorylations on the binding affinity of ephrinB2(301–333) to the SH2 domain of Grb4 and to the PDZ domain of PDZ-RGS3. In the combination experiments, the two C terminal ... detect the binding interactions between the peptides and the Grb4 SH2 domain. The affinity of the binding interactions was evaluated by measuring the changes of fluorescence polarization of the peptides...

The elution patterns of zinc were similar in the ovary and testis, but the zinc peak in the immature ovary was larger than that in the immature testis, Zinc-binding protein in the sea urchin ... testis (Fig. 1C), zinc eluted as three or four major peaks. One of the zinc peaks was coincident with the MYP peak in both the ovary and the testis, indicating that part of the zinc in the immature ... contrast, part of the incorporated CFMYP is not processed to EGMYP, enabling it to retain zinc. Indeed, 33% of the total zinc in the ovary at stage 1 and 13% of the total zinc in the testis at...
