This gene encodes a bifunctional signal transduction molecule. Dopaminergic and glutamatergic receptor stimulation regulates its phosphorylation and function as a kinase or phosphatase inhibitor. As a target for dopamine, this gene may serve as a therapeutic target for neurologic and psychiatric disorders. Multiple transcript variants encoding different isoforms have been found for this gene.

A study in human postmortem brain tissue identified the PPP1R1B as a striatal marker enriched in the nucleus accumbens of unaffected comparison subjects [Seney et al. DOI:10.1016/j.biopsych.2021.06.007].
