Function

This protein is an orphan class C GPCR. It is highly expressed in the brain, where it binds to RGS7, an inhibitor of G_i/o-coupled GPCR signaling, localizing it to the plasma membrane.^[7]

It is expressed at lower levels in other organs and shows an unusual subcellular localization pattern, being found at both the plasma membrane and in the nucleus.^[8]

Clinical significance

Role in mood regulation

GPR158 in the medial prefrontal cortex (mPFC) has been shown to regulate stress-induced depression in a mouse model of depression and has been found to be upregulated in post-mortem tissue samples from humans with major depressive disorder (MDD).^[9]

Role in prostate cancer

The GPR158 gene is an androgen-regulated gene that stimulates cell proliferation in prostate cancer cell lines, and it is linked to neuroendocrine differentiation.^[10]
