OCT7 — Solanum tuberosum

Summary

PGSC0003DMG400009029, designated StOCT7 on potato chromosome 1, encodes a protein with GAP activity, belonging to the RanGAP1/2 family and containing WPP and leucine-rich repeat domains. The gene is associated with multiple biological processes including mitosis, localization, secretion, innate immunity, defense response, signal transduction, cell death, response to virus, and virus-induced post-transcriptional gene silencing. It is also associated with biofilm formation. The encoded protein localizes to the nuclear envelope and cytoplasm. Studies of related genes in other species connect the family to sugar transport and receptor-like kinase signaling, though these functions are not established for StOCT7 itself.
