The chimeric leucine-rich repeat/extensin cell wall protein LRX1 is required for root hair morphogenesis in Arabidopsis thaliana.
In plants, the cell wall is a major determinant of cell morphogenesis. Cell enlargement depends on the tightly regulated expansion of the wall, which surrounds each cell. However, the qualitative and quantitative mechanisms controlling cell wall enlargement are still poorly understood. Here, we report the molecular and functional characterization of LRX1, a new Arabidopsis gene that encodes a c...
متن کاملRole of leucine-rich repeat proteins in the development and function of neural circuits.
The nervous system consists of an ensemble of billions of neurons interconnected in a highly specific pattern that allows proper propagation and integration of neural activities. The organization of these specific connections emerges from sequential developmental events including axon guidance, target selection, and synapse formation. These events critically rely on cell-cell recognition and co...
متن کاملBK potassium channel modulation by leucine-rich repeat-containing proteins.
Molecular diversity of ion channel structure and function underlies variability in electrical signaling in nerve, muscle, and nonexcitable cells. Regulation by variable auxiliary subunits is a major mechanism to generate tissue- or cell-specific diversity of ion channel function. Mammalian large-conductance, voltage- and calcium-activated potassium channels (BK, K(Ca)1.1) are ubiquitously expre...
متن کاملMini-Review Leucine-Rich Repeat Proteins of Synapses
Leucine-rich repeats (LRRs) are 20–29-aa motifs that mediate protein–protein interactions and are present in a variety of membrane and cytoplasmic proteins. Many LRR proteins with neuronal functions have been reported. Here, we summarize an emerging group of synaptic LRR proteins, which includes densin-180, Erbin, NGL, SALM, and LGI1. These proteins have been implicated in the formation, differ...
متن کاملRole of the extensin superfamily in primary cell wall architecture.
Nearly two centuries of progress have established the major components of the plant cell wall, a composite that includes interpenetrating networks of cellulose (Payen, 1838; Schulze, 1891), microfibrils (Frey-Wyssling et al., 1948; Preston et al., 1948), pectin (Braconnot, 1825) and lignin (Payen, 1838). However, only over the last five decades has a relatively minor hydroxyproline-rich structu...
