Phosphatidylinositol 3-kinase regulatory subunit beta is an enzyme that in humans is encoded by the PIK3R2 gene.[4][5]

A recent study on gene expression indicated that the PIK3R2 gene might have a key role in pan-cancer prognosis.[6]

Interactions

PIK3R2 has been shown to interact with:

Clinical relevance

PIK3R2 mutations were recently shown to be associated with polymicrogyria.[12]
