In addition to lipid transport and assembly, nsLTPs also play a key role in the defense of plants against pathogens. There are two closely-related types of nsLTPs, types 1 and 2, which differ in protein sequence, molecular weight, and biological properties. nsLTPs contain an internal hydrophobic cavity, which serves as the binding site for lipids. nsLTP2 can bind lipids and sterols. Structure studies of rice nsLTPs show that the plasticity of the hydrophobic cavity is an important factor in ligand binding. The flexibility of the sLTP2 cavity allows its binding to rigid sterol molecules, whereas nsLTP1 cannot bind sterols despite its larger cavity size. The resulting nsLTP2/sterol complexes may bind to receptors that trigger defense responses. nsLTP2 gene exp

In addition to lipid transport and assembly, nsLTPs also play a key role in the defense of plants against pathogens. There are two closely-related types of nsLTPs, types 1 and 2, which differ in protein sequence, molecular weight, and biological properties. nsLTPs contain an internal hydrophobic cavity, which serves as the binding site for lipids. The hydrophobic cavity accommodates various fatty acid ligands containing from ten to 18 carbon atoms. In general, the cavity is larger in nsLTP1 than in nsLTP2. nsLTP1 proteins are located in extracellular layers and in vacuolar structures. They may be involved in the formation of cutin layers on plant surfaces by transporting cutin monomers. Many nsLTP1 proteins have been characterized as allergens in humans.

In addition to HPS, members of this subfamily include a hybrid proline-rich protein (HyPRP) from maize, a dark-inducible protein (LeDI-2) from Lithospermum erythrorhizon, maize ZRP3 protein, and rice RcC3 protein. HyPRP is an embryo-specific protein that contains an N-terminal proline-rich domain and a C-terminal HPS-like cysteine-rich domain. It has been suggested that HyPRP may be involved in the stability and defense of the developing embryo. LeDI-2 is a root-specific protein that may be involved in regulating the biosynthesis of shikonin derivatives in L. erythrorhizon. Maize ZRP3 and rice RcC3 are root-specific proteins whose functions are yet to be determined. It has been reported that ZRP3 largely accumulates in a distinct subset
>cd00261 AAI_SS AAI_SS: Alpha-Amylase Inhibitors (AAIs) and Seed Storage (SS) Protein subfamily; composed of cereal-type AAIs and SS proteins
They are mainly present in the seeds of a variety of plants. AAIs play an important role in the natural defenses of plants against insects and pathogens such as fungi, bacteria and viruses. AAIs impede the digestion of plant starch and proteins by inhibiting digestive alpha-amylases and proteinases. Also included in this subfamily are SS proteins such as 2S albumin, gamma-gliadin, napin, and prolamin. These AAIs and SS proteins are also known allergens in humans.
