We review here recent results on the structure and function of a receptor protein tyrosine phosphatase, RPTPmicro. In addition to their intercellular catalytic domains which bear the phosphatase activity, the RPTPs are cell-surface-receptor-type molecules and in many cases have large extracellular regions. What role can these extracellular regions play in function? For RPTPmicro, the extracellular region is known to mediate homophilic adhesion. Sequence analysis indicates that it comprises si...Expand abstract
