title: Molecular cloning of two additional members of the neural visinin-like Ca(2+)-binding protein gene family.
abstract: We have isolated a rat cDNA clone encoding a neural visinin-like Ca(2+)-binding protein (NVP), which we designate NVP-1. To identify additional molecular forms of NVP, a rat brain cDNA library was screened for their presence using an NVP-1 cDNA probe under low-stringency hybridization conditions. Two types of cDNA clones encoding structurally related proteins, designated NVP-2 and NVP-3, have been isolated. The deduced amino acid sequences of NVP-2 and NVP-3 are 89.0% and 68.6% identical to that of NVP-1, respectively, and contain consensus sequences for EF-hand Ca(2+)-binding sites. Northern blot analysis shows that NVP-1, NVP-2, and NVP-3 mRNAs are most highly expressed in brain and are differentially expressed in various regions of rat brain. These results suggest that NVP-2 and NVP-3 are additional members of the NVP gene family.
