The crystal structure of domain 1 of receptor protein-tyrosine phosphatase mu.
K.M.Hoffmann, N.K.Tonks, D.Barford.
Receptor-like protein-tyrosine phosphatases (RPTPs) play important roles in regulating intracellular processes. We have been investigating the regulation and function of RPTPmu, a receptor-like PTP related to the Ig superfamily of cell adhesion molecules. Recently, the crystal structure of a dimer of the membrane proximal domain of RPTPalpha (RPTPalpha D1) was described (Bilwes, A. M., den Hertog, J., Hunter, T., and Noel J. P. (1996) Nature 382, 555-559). Within this crystal structure, the catalytic site of each subunit of the dimer is sterically blocked by the insertion of the N-terminal helix-turn-helix segment of the dyad-related monomer. It was proposed that dimerization would lead to inhibition of catalytic activity and may provide a paradigm for the regulation of the RPTP family. We have determined the crystal structure, to 2.3 A resolution, of RPTPmu D1, which shares 46% sequence identity with that of RPTPalpha D1. Although the tertiary structures of RPTPalpha D1 and RPTPmu D1 are very similar, with a root mean square deviation between equivalent Calpha atoms of 1.1 A, the quaternary structures of these two proteins are different. Neither the catalytic site nor the N-terminal helix-turn-helix segment of RPTPmu D1 participates in protein-protein interactions. The catalytic site of RPTPmu D1 is unhindered and adopts an open conformation similar to that of the cytosolic PTP, PTP1B (Barford, D., Flint, A. J., and Tonks, N. K. (1994) Science 263, 1397-1404). We propose that dimerization-induced modulation of RPTP activity may not be a general feature of this family of enzymes.

Figure 1.
Fig. 1. Ribbon diagram of the receptor PTPµ D1 dimer. The molecular dyad axis is indicated by an arrow. The catalytic site^ cysteine (Cys1095), the helix-turn-helix segment ( 1 , 2 ), and the N-terminal -strand ( x) that forms a -sheet with y within RPTPs D1 are^ indicated within one subunit (left). The 8 and 10 strands participate^ in the dimer interface of RPTPµ D1. C atoms of the equivalent catalytic site residues that form the dimer interface of RPTP D1 are shown as spheres and labeled. Figure was drawn using MOLSCRIPT (22).
Figure 3.
Fig. 3. Sequence alignment of representative RPTP D1s in the regions that form the dimer interfaces of RPTP and RPTPµ. Top left, x-helix-turn-helix segment; top right, residues of the^ Tyr(P) recognition loop of the catalytic site. Bottom, residues from 8 through to the WPD loop of the catalytic site. Residues of RPTPµ D1 and RPTP D1 that form interactions at their respective^ dimer interfaces are indicated with vertical arrows (top) and^ stars (bottom), respectively. The residues that form the dimer interface of RPTPµ D1 are poorly conserved throughout the family, whereas residues of the RPTP D1 interface are poorly conserved^ within the helix-turn-helix segment, but well conserved within the catalytic site. Invariant residues are in white type on a^ black background, and highly conserved residues are boxed.

The most recent references are shown first. Citation data come partly from CiteXplore and partly from an automated harvesting procedure. Note that this is likely to be only a partial list as not all journals are covered by either method. However, we are continually building up the citation data so more and more references will be included with time. Where a reference describes a PDB structure, the PDB code is shown on the right.
