In spite of the potential importance in mediating plant calcium signaling, the physiological functions of the Arabidopsis CaMs and CMLs remain largely unknown. 展开 关键词: Arabidopsis thaliana, amino acid sequences, gene expression regulation, calcium, literature reviews, signal transduction, calmodulin-...
1, full-length T7-IQD1 co-sedimented with all tested CaMs and CMLs only in the presence of Ca2+, and binding was abolished when EGTA was added to the buffer. In summary, the data confirm our previous results with bovine CaM (16) and demonstrate the capacity of Arabidopsis IQD1 to ...
This indicates that they can function in a similar manner as canonical CaMs. The presence of close homologues to AtCML3 and AtCML30 in other plants further indicates that organellar targeting of these CMLs is not a specific feature of Arabidopsis . The identification of peroxisomal and ...
Number and structural diversity of the EF hands are evaluated. Intron/exon boundaries, phylogenetic tree and chromosomal distribution data for the CAMs and CMLs are presented. Arabidopsis has 6 CAM genes, encoding only 3 isoforms. Maintenance of these genes suggests that they are unlikely to be ...
In response to these stimuli, cells generate transient changes in the intracellular Ca2+ concentration and, these changes are sensed and decoded by Ca2+ sensors including calmodulins (CaMs), calmodulin-like proteins (CMLs), calcineurin B-like proteins (CBLs) and calcium-dependent protein kinases (...

The Ca2+ sensors, including calmodulins (CaMs), CaM-like proteins (CMLs), calcineurin B-like proteins (CBLs), and CPKs, decode the cold-triggered Ca2+ signals to the downstream signaling events [3]. In this study, we identified cold-responsive phosphopeptides representing over 60 proteins invo...
Calcium is a second messenger known to activate four different categories of calcium sensor proteins: calmodulins (CaMs), CaM-like proteins (CMLs), calcium-dependent protein kinases (CDPKs) and calcineurin B-like proteins (CBLs) [23, 24]. Among the 34 CDPKs of the Arabidopsis genome [25]...
