The cDNA libraries constructed from the human acute lymphoblastic leukemia cell line KM3 in the expression vector lambda gt11, were screened with the anti-CALLA (common acute lymphoblastic leukemia antigen) mAb (monoclonal antibody) J5. The selected J5-positive clone I containing a partial cDNA insert was isolated and sequenced. For completing the cDNA sequence the cDNA libraries were further screened by hybridization with the DIG (digoxigenin)-labelled DNA probe derived from clone I, the 5'-end region was analysed by 5'-RACE (rapid amplification of cDNA ends) using a sequence specific primer. In total a 1639 bp cDNA sequence was determined. The cDNA sequence contains a 1260 bp open reading frame and the untranslated 3'- and 5'-end sides. The 420 residue amino acid sequence, deduced from the cDNA sequence, unexpectedly differs fundamentally from CALLA (CD10) although clones I and II were J5-positive in immuno screening. The mature protein corresponding to the cDNA was isolated and characterized from the KM3 cells using polyclonal antisera raised against the in vitro expressed polypeptide from clone I. The protein is expressed on plasma membrane, in cytosol and is secreted into culture medium, its relative molecular mass was determined to be 55 kDa on SDS-PAGE. The deduced amino acid sequence from cDNA was confirmed by peptide sequences. The new protein contains a basic amino acid rich putative DNA binding domain (b) with a potential nuclear targeting signal, two helix-loop-helix (HLH) motif regions, concurrently EF-hand motifs, an acidic amino acid rich region (a) between the EF-hands, and a leucine zipper (Z) motif. This DNA binding protein therefore is characterized by a linked motif "b/HLH/a/HLH/Z". The protein was designated NEFA: DNA binding/EF-hand/acidic amino acid rich region.
