tokens: Functional analysis of various PTP deficient DT40 B cell lines stably expressing wild-type chimeric Fc gamma RIIB1-PECAM-1 receptor indicated that cytoplasmic Src homology 2-domain containing phosphatases , SHP-1 and SHP-2 , were both necessary and sufficient to deliver inhibitory negative regulation upon coligation of BCR complex with inhibitory receptor .
