This gene encodes a thaumatin-like protein[1].
Contents
Annotated Information
Function
This gene encodes a thaumatin-like protein. Thaumatin belongs to the pathogen response 5(PR5) family, and is only exclusively expressed in pathological
conditions such as paramicrobe infection or mechanical damage[2]. Therefore, it is thought that this protein is involved in acquired systematic resistance
and the response to biotic stress; the latter process leads to microbe growth inhibition and spore germination reduction[2]. However, the precise mechanism
in rice is unknown. In addition, this thaumatin-like peotein harbors ATP-binding potentiality and Serine/threonine-protein kinase activity according to
the homology prediction[3]. And an attractive feature of this protein is its sweet flavor, and this feature may be used in food industry[4].

Expression
This thaumatin-like protein is derived from the rice cultivar Nipponbare[5]. The name 'thaumatin-like' from its homology with thaumatin. Thaumatin
is firstly extracted from the fruit Thaumatococcus daniellii growing in West Africa[4]. Thaumatin-like proteins are in diverse plants, and can be
isolated from Hordeum vulgare (barley), Actinidia deliciosa(kiwifruit), Zea mays (maize), Pseudotsuga menziesii (douglas-firs), Nicotiana tabacum (tobacco),
Solanum lycopersicum (tomato) and Triticum sp. (wheat) . Most of the thaumatin-like protein have a molecular weight in the range of 18 kDa to 25 kDa and
have a pH in the range from 4.5 to 5.5.[2]
---
Evolution
Thaumatin-like proteins appear to have originated in early eukaryotes and share a well-defined thaumatin-like protein domain[6]. Evolutionary
relationships within the thaumatin-like protein superfamily are not well understood. For example, a study of phylogenetic and structural relationships[7],
suggested that plant PR5 proteins are paraphyletic in angiosperms and related to animal thaumatin-like proteins from insects and nematodes. However,
another study indicated that thaumatin-like proteins are grouped into three major clades representing the animal, plant, and fungal kingdoms, respectively.Alignment
analysis was done using 118 putative TLP sequences selected from ascomycete and basidiomycete fungi, moss, gymnosperms and angiosperms, plus animals as represented
by nematodes and insects. The neighbor joining algorithm was used to construct a phylogenetic tree (Fig. 3). The topological pattern of the resulting tree indicates
that the TLP superfamily is highly divergent, with the possibility of nine distinct groups (I–IX), each containing proteins with relatively high identity[8].
