The function of GDPGP1 (GDP-D-glucose phosphorylase 1, ENSG00000183208) is as follows. Specific and highly efficient GDP-D-glucose phosphorylase regulating the levels of GDP-D-glucose in cells (PubMed:21507950). Is involved in adaptive response to stress conditions, and plays a key role in neuronal stress resistance by modulating neuronal glycogen levels and maintaining glucose balance (By similarity). .
