這個基因編碼受體蛋白酪氨酸磷酸酶家族的一個成員。該基因的表達僅限于中樞神經系統，可能參與中樞神經系統特定發育過程的調控。另外，編碼不同亞型的剪接轉錄變體已經被描述為該基因。
This gene encodes a member of the receptor protein tyrosine phosphatase family. Expression of this gene is restricted to the central nervous system (CNS), and it may be involved in the regulation of specific developmental processes in the CNS. Alternatively spliced transcript variants encoding different isoforms have been described for this gene.
