We have identified two novel human SCAN domain genes ZNF396 and ZNF397, which are clustered within the region of chromosome 18q12. Three isoforms of ZNF396 transcript, 1.5, 2.5 and 3.9-kb, are expressed highly in liver. Four isoforms of ZNF397 transcript, 1.7, 2.5, 7.0 and 9.0-kb, are expressed in a variety of tissues, with varying levels. The SCAN-(C(2)H(2))(X) genes encode two distinct proteins due to a unique alternative splicing mechanism. Both ZNF396-fu (full zinc fingers) and ZNF397-fu consist of a SCAN domain in the N-terminal region and many consecutive C(2)H(2) zinc finger repeats in the C-terminal region. ZNF396-nf (no zinc fingers) and ZNF397-nf encode 210 and 198 amino acids, respectively, containing the SCAN domain only. ZNF396-fu, ZNF396-nf, ZNF397-fu or ZNF397-nf can homo-associate, while ZNF396-fu hetero-associates with ZNF396-nf, and ZNF397-fu hetero-associates with ZNF397-nf. ZNF396-nf and ZNF397-nf polypeptides are expressed diffusely in the cells, while ZNF396-fu and ZNF397-fu polypeptides target specifically to the nuclei. ZNF396-fu, ZNF396-nf and ZNF397-nf can repress reporter gene transcription, with ZNF397-nf having the strongest repression activity. Deletion analysis revealed that ZNF397-fu is a transcriptional activator without its nine zinc finger repeats.
