Annotated Information

Function

ILA1 is a functional kinase with Ser/Thr kinase activity.ILA1 is a key factor regulating mechanical tissue formation at the leaf lamina joint and is involved in mechanical tissue formation in the leaf lamina joint.<ref name="ref1" / >

Expression

ILA1 is predominantly resident in the nucleus and expressed in the vascular bundles of leaf lamina joints.The leaf angle of WT is increased compared that of ila1. But the increased leaf angle of ila1 is not due to altered BR. ILA1 mutation significantly represses the expression of genes involved in cell wall synthesis and consequently causes the increased leaf responses. ILA1 encodes a putative MAPKKK protein with a length of 564 amino acids and a molecular mass of 63 kD. According to the Pfam database, the deduced ILA1 has an N-terminal ACT domain (PF01842) and a C-terminal kinase domain (PF07714), which likely confer a protein regulatory feature and kinase activity, respectively. Sequence alignment of ILA1 with several identified MAPKKKs from three representative plant species revealed that the characteristic features for MAPKKK proteins, including all of the 11 subdomains and a Lys in the ATP binding site, are highly conserved in ILA1. ILA1 represents a potentially unique paradigm in the regulation of leaf angle in rice. QRT-PCR analysis revealed high expression levels of ILA1 in both leaves and leaf lamina joints. However,ila1 exhibits a visible phenotype mainly in its leaf lamina joints butnot in its leaves.

Evolution

MAPKKKs generally phosphorylate target proteins to mediate signal transduction.ILA1 Interacts with a Functionally Unidentified Protein Family. The kinase domain of ILA1 is involved in the interaction with IIPs in subfamily B, but not with IIPs in subfamily A.

You can also add sub-section(s) at will. possible mechanism of ILA1 action Identification of ILA1 phosphorylation substrates is critical for understanding the signal transduction pathway of a Group C Raflike MAPKKK member. Through yeast two-hybrid screening of the cDNA library, six interaction proteins (IIPs) were found; these IIPs consist of a small family with unknown functions. The interactions were further confirmed by the BiFC and Co-IP analyses of a representative IIP. More importantly,ILA1 could phosphorylate an IIP in vitro. IIPs are thus likely to be the authentic downstream targets of ILA1. IIPs may act as transcription factors for they were regarded as putative transcription factors by bioinformatic analysis;they are nuclear localized in rice and they showed transactivation activity in yeast.
