The protein encoded by this gene contains a RING finger motif and is similar to the polycomb group (PcG) gene products. PcG gene products form complexes via protein-protein interaction and maintain the transcription repression of genes involved in embryogenesis, cell cycles, and tumorigenesis. This protein was shown to act as a negative regulator of transcription and has tumor suppressor activity. The expression of this gene was detected in various tumor cells, but is limited in neural organs in normal tissues. Knockout studies in mice suggested that this protein may negatively regulate the expression of different cytokines, chemokines, and chemokine receptors, and thus plays an important role in lymphocyte differentiation and migration, as well as in immune responses.

A study in mice demonstrated that the PCGF2 mRNA was up-regulated 2.52-fold in bone marrow cells 6 hours after a 6.5 Gy whole-body ionizing radiation exposure, as identified by microarray analysis [Dai et al. DOI:10.1080/09553000600857389]. This differential expression was part of a broader transcriptional response involving 103 genes, with validation techniques including RT-PCR confirming the microarray data for selected genes, though the specific validation of the PCGF2 was not detailed.
