SLFN12
Function
Ribonuclease which is part of an E2/17beta-estradiol-induced pro-apoptotic signaling pathway. E2 stabilizes the PDE3A/SLFN12 complex in the cytosol, promoting the dephosphorylation of SLFN12 and activating its pro-apoptotic ribosomal RNA/rRNA ribonuclease activity. This apoptotic pathway might be relevant in tissues with high concentration of E2 and be for instance involved in placenta remodeling (PubMed:31420216, PubMed:34272366, PubMed:34707099, PubMed:35104454). May play a role in cell differentiation (PubMed:30045019).
Post-translational modifications
Phosphorylation at Ser-368 and Ser-573 negatively regulates the ribonuclease activity (PubMed:35104454). Dephosphorylation is induced by the interaction with PDE3A and stimulates the rRNA ribonuclease activity (PubMed:35104454).
