With the aim of identifying genes involved in early human embryonic development, we have isolated a cDNA clone representing a novel human zinc finger gene ZNF268 from 3 week old human embryo cDNA library using a differential hybridization strategy. The complete cDNA sequence of ZNF268 contained an open reading frame of 2841 nucleotides that encodes a 947 amino acid protein with an N-terminal Krüppel-associated box (KRAB) domain and 24 C-terminal zinc fingers. Northern blot analysis showed that ZNF268 mRNA is mainly expressed in 3-5 week old human embryos suggesting it could play certain roles in the embryogenesis. The gene consists of six exons spanning about 22 kb of genomic DNA. According to the genomic sequence from the HTGS database, the ZNF268 gene is assigned to human chromosome 5.
