Cloning, expression and chromosomal assignment of human pleckstrin2

We report the isolation of human pleckstrin 2 cDNA. The cDNA contains a 1059 bp open reading frame encoding a polypeptide of 353 amino acid residues. The deduced amino acid sequence indicates that pleckstrin 2contains two pleckstrin homology domains and a DEP (dishvelled, egl-10, and pleckstrin) domain and had a 95% identity with the sequence of mouse pleckstrin 2. Northern blot and a reverse transcription-coupled polymerase chain reaction analysis revealed that pleckstrin 2 mRNA is widely expressed in a variety of cell lines. The chromosomal location of the mouse pleckstrin 2 gene was on the D3 band of chromosome 12, as determined by fluorescence in situhybridization and the human pleckstrin 2 gene was mapped to chromosome 14q24.1 by a bioinformatics analysis.
