Receptor like protein tyrosine phosphatase zeta (RPTPz) (also known as RPTPbeta or PTPxi) is a tyrosine phosphatase widely expressed in the nervous system, thought to play a role in cell-cell communication. However, knocking out RPTPz does not induce major neural abnormalities in mice. In order to better assess the potential role of RPTPz in various neural functions, we performed a comprehensive behavioural characterization of CNS/PNS functions in knockout mice (RPTPz -/-) confirming previously observed impaired working memory functions and further demonstrating an altered motor coordination. Moreover, RPTPz -/- mice displayed reduced responses to moderate thermal and tactile stimuli, both in baseline and under inflammatory conditions. These findings assign novel functional role of RPTPz in motor coordination and nociception.
