LP2 — Capsicum annuum

Summary

CaLP2 (LP2) on pepper chromosome 10 encodes a non-specific lipid transfer protein (nsLTP) belonging to the bifunctional inhibitor/LTP/seed storage superfamily. The product exhibits lipid carrier activity, lipid binding, and IgE binding, and is associated with phospholipid transfer to membranes, lipid transport, cutin anabolism, and cuticle development. It has been linked to fruit ripening, anther and pollen development, pollen germination, plant epidermal cell differentiation, programmed cell death, defense responses, virus-induced PTGS, and response to thirst. The protein localizes to the plasma membrane, cell wall, plasmodesmata, Golgi, endosome, TGN, and extracellular space. Associations include photosynthetic rate, drought tolerance, cold tolerance, flowering time, cuticle integrity, shoot and root development, hypocotyl elongation, gravitropism, seed set, and pollen tube growth. Studies of related genes in other species connect the family to pathogen resistance, salt tolerance, yield, and nitrogen use efficiency.
