Disease relevance of LTP2

• The activity of three different promoters (Cauliflower Mosaic Virus (CaMV) 35S, modified CaMV 35S and the promoter of an Arabidopsis thaliana Lipid Transfer Protein gene) was shown to vary not only among independent transformants, but also between leaves on the same plant and within a leaf [1].

High impact information on LTP2

• DIR1 encodes a putative apoplastic lipid transfer protein and we propose that DIR1 interacts with a lipid-derived molecule to promote long distance signalling [2].
• A permease-like protein involved in ER to thylakoid lipid transfer in Arabidopsis [3].
• Interestingly, many genes thought to be responsible for cold acclimation such as COR, lipid transfer protein, and beta-amylase, that are highly induced in Arabidopsis leaves, were only expressed at their normal level or weakly induced in the pollen [4].
• Sequence analysis of full-length cDNAs showed that one of the novel genes, ATA7, encodes a protein related to lipid transfer proteins [5].
• ROP8, PLDdelta, and lipid transfer proteins were among the differentially expressed genes between the two genotypes [6].

Other interactions of LTP2

• Crystallization of DIR1, a LTP2-like resistance signalling protein from Arabidopsis thaliana [7].
• The polypeptide backbone of xylogen is a hybrid-type molecule with properties of both arabinogalactan proteins and nonspecific lipid-transfer proteins [8].
