| Abstract |
The interaction of human visinin-like protein 1 (VILIP1) and visinin-like protein 3 (VILIP3) with divalent cations (Mg2+, Ca2+, Sr2+ and Ba2+) was explored using circular dichroism and fluorescence measurement. These results showed that the four cations each induced a different subtle change in the conformation of VILIPs. Moreover, VILIP1 and VILIP3 bound with Ca2+ or Mg2+ in a cooperative manner. Studies on the truncated mutants showed that the intact EF-3 and EF-4 were essential for the binding of VILIP1 with Ca2+ and Mg2+. Pull-down assay revealed that Ca2+ and Mg2+ enhanced the intermolecular interaction of VILIPs, and led to the formation of homo- and hetero-oligomer of VILIPs. Together with previous findings that Ca2+-dependent localization of VILIPs may be involved in the regulation of distinct cascades and deprivation of Ca2+-binding capacity of VILIPs did not completely eliminate their activity, it is likely to reflect that Mg2+-bound VILIPs may play a role in regulating the biological function of VILIPs in response to a concentration fluctuation of Ca2+ in cells. |

Attention Score in Context
This research output has an Altmetric Attention Score of 3. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 20 December 2007.
All research outputs
#8,534,976
of 25,373,627 outputs
Outputs from The Protein Journal
#163
of 639 outputs
Outputs of similar age
#29,495
of 86,412 outputs
Outputs of similar age from The Protein Journal
#2
of 4 outputs
Altmetric has tracked 25,373,627 research outputs across all sources so far. This one is in the 43rd percentile – i.e., 43% of other outputs scored the same or lower than it.
So far Altmetric has tracked 639 research outputs from this source. They receive a mean Attention Score of 3.7. This one is in the 31st percentile – i.e., 31% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 86,412 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 13th percentile – i.e., 13% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 4 others from the same source and published within six weeks on either side of this one. This one has scored higher than 2 of them.
