p11 as a functional modulator of its binding partners at the plasma membrane and in the nucleus. p11 dimer or p11/AnxA2 heterotetrameric complex regulates serotonin, glutamate, or calcium signaling by increasing levels of 5-HTRs (A), mGluR5 (B) or L-type VGCCs (C) at the plasma membrane. The heterotetrameric p11/AnxA2 complex also binds to Smarca3 (D) or Supt6h (E) and regulates Smarca3- or Supt6h-mediated chromatin remodeling, epigenetic modifications, and gene transcription. These cell surface and nuclear actions underlie depressive or antidepressant-like behavioral effects of genetic modulations of p11 and its binding partners. This figure was created with BioRender.com.
