AT2S1 — Brassica oleracea

Summary

BoAT2S1 (AT2S1, SESA1) on cabbage chromosome 1 encodes a napin/2S seed storage protein belonging to the bifunctional inhibitor/lipid-transfer/seed-storage superfamily and is annotated with nutrient reservoir activity. The gene is associated with seed development, seed storage protein accumulation, and nitrogen storage, and its product localises to the extracellular space. BoAT2S1 has been linked to seed protein content and protein content traits. Studies of related genes in other species connect the family to seed weight, seed size, seed maturation, raffinose content, amino acid content, chlorophyll content, drought tolerance, and organ identity, though these associations are not established for BoAT2S1 itself. The gene is related to NAPB and NAP1.
