LP2 — Lactuca sativa

Summary

LsLP2 (LP2) on lettuce chromosome 1 encodes a protein belonging to the Plant_nsLTP family, with bifunctional inhibitor/lipid-transfer and seed-storage domains. The gene product is annotated for nutrient reservoir activity, lipid binding, and IgE binding, and is localized to the extraorganismal space. LsLP2 is associated with lipid transport, seed development, digestion, and defense responses, including the killing of other organism cells and defense response to fungi. Related genes in other species, such as LTP Cor a 8 and nsLTP Lac s 1, link the family to allergenicity and lipid transfer functions.
