Summary: Predicted to enable 1-phosphatidylinositol-3-kinase activity and 1-phosphatidylinositol-4-phosphate 3-kinase activity. Predicted to be involved in cell migration; intracellular signal transduction; and phosphatidylinositol-3-phosphate biosynthetic process. Predicted to act upstream of or within autophagosome organization and cellular response to starvation. Predicted to be located in cytosol; endocytic vesicle; and nucleoplasm. Predicted to be active in cytoplasm and plasma membrane. Orthologous to human PIK3C2B (phosphatidylinositol-4-phosphate 3-kinase catalytic subunit type 2 beta).

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
