The protein encoded by this gene is a regulatory subunit of the serine/threonine-protein phosphatase 4 complex. In addition to being required for efficient DNA double strand break repair, this complex plays a role in organization of microtubules at centrosomes and processing of spliceosomal snRNPs. Several transcript variants encoding different isoforms have been found for this gene. PPP4R2 (Protein Phosphatase 4 Regulatory Subunit 2) is a Protein Coding gene. Among its related pathways are DNA Double-Strand Break Repair. GO annotations related to this gene include protein binding, bridging.
