Figure 5From: Structure function analysis of SH2D2A isoforms expressed in T cells reveals a crucial role for the proline rich region encoded by SH2D2A exon 7Tyrosines within aa239–334 determines the inhibitory effect of TSAd on Lck activity. The phosphorylation level of LAT and Y319 of Zap-70 in Jurkat T cells expressing the SH2D2A-5 variant and TSAd-4YF is normal upon TCR stimulation: Jurkat T cells were transiently transfected with either pEF-HA or one of the pEF-HA-SH2D2A-1-5 or pEF-HA-TSAd-4YF cDNAs. The cells were stimulated (+) with anti-CD3 (OKT3) mAbs for 2.5 min and lysed. The lysates were immunoblotted with Abs as indicated.Back to article page
