    ..We propose that during T cell development, CD45 ligation could induce the death of those immature thymocytes that do not fulfill the requirements for positive selection. ..

    ..These results suggest that the region including Lys-273 of subdomain II is involved in the enzymatic process of phosphate transfer, rather than in anchoring ATP. ..
