Using the interaction - trap assay to identify candidate proteins that bind the cytoplasmic region of the LAR transmembrane protein tyrosine phosphatase ( PT - Pase ) , we isolated a cDNA encoding a 2861 - amino acid protein termed Trio that contains three enzyme domains : two functional GEF domains and a protein serine / threonine kinase ( PSK ) domain .
 GENE: LAR transmembrane protein tyrosine phosphatase; GENE: PT - Pase; GENE: Trio; GENE: GEF domains; GENE: protein serine / threonine kinase; GENE: PSK
