The fifty nine primer binds at the start of the third PTB area of HMTK1 (residue 341) we were being not profitable in amplifying a cDNA making use of primers at the fifty nine finish of the gene design, or at the commencing of the very first or next PTB domains.

The equipment needed for phosphotyrosine-based signaling in metazoans involves ``writer'' domains (tyrosine kinases), ``readers'' (SH2 and PTB domains), and ``erasers'' (tyrosine phosphatases) . Genome analyses suggest that ``eraser'' domains emerged…
