== Function ==
[https://www.uniprot.org/uniprot/PDE6D_HUMAN PDE6D_HUMAN] Acts as a GTP specific dissociation inhibitor (GDI). Increases the affinity of ARL3 for GTP by several orders of magnitude and does so by decreasing the nucleotide dissociation rate. Stabilizes Arl3-GTP by decreasing the nucleotide dissociation (By similarity).

== Publication Abstract from PubMed ==
Structural biology is a powerful tool for investigating the stereospecific interactions between a protein and its ligand. Herein, an unprecedented chiral binding pattern was observed for inhibitors of KRAS-PDEdelta interactions. Virtual screening and X-ray crystallography studies revealed that two enantiomers of a racemic inhibitor could bind at different sites. Fragment-based drug design was used to identify highly potent PDEdelta inhibitors that can be used as promising lead compounds for target validation and antitumor drug development.
