PPP6R2 (Protein Phosphatase 6 Regulatory Subunit 2): PPP6R2 is a gene that encodes a regulatory subunit of protein phosphatase 6 (PP6). PP6 participates in the dephosphorylation of target proteins and plays essential roles in regulating the cell cycle, repairing DNA damage, and cellular signalling. PPP6R2 helps regulate the activity and specificity of PP6, impacting these vital cellular processes.
