Disease relevance of AT5G64220

By analyzing the calmodulin binding activity of truncated proteins expressed in Escherichia coli, the calmodulin binding region is mapped to a stretch of about 50 amino acid residues in the COOH terminus region of the protein [1].

High impact information on AT5G64220

We reported earlier that the tobacco early ethylene-responsive gene NtER1 encodes a calmodulin-binding protein (Yang, T., and Poovaiah, B. W. (2000) J. Biol. Chem. 275, 38467-38473) [2].
These results suggest that the AtSR gene family encodes a family of calmodulin-binding/DNA-binding proteins involved in multiple signal transduction pathways in plants [2].
A novel plant calmodulin-binding protein with a kinesin heavy chain motor domain [1].
Calmodulin-binding proteins also have a calmodulin-like binding site within their structure. The flip-flop model [3].
IQD1 encodes a novel protein that contains putative nuclear localization signals and several motifs known to mediate calmodulin binding, which are arranged in a plant-specific segment of 67 amino acids, called the IQ67 domain [4].

Biological context of AT5G64220

Using radiolabeled recombinant calmodulin as a probe to screen a tobacco cDNA library, we have discovered a protein designated NtCBP4 (Nicotiana tabacum calmodulin-binding protein) that can modulate plant tolerance to heavy metals [5].
