[Cloning and identification of a new telomeric-associated zinc finger protein cDNA].

In order to isolate novel genes related to early human embryo development and differentiation, a directional cDNA library was constructed from 3-week-old human embryo. Single-pass DNA sequence analysis was used to sequence 47 randomly picked low-abundance cDNA clones. This approach led us to select a clone, L30, showing significant homology with the telomeric-associated DNA and zinc finger protein genes. It is about 3.8 kb in length and contains an open reading frame of notable length within 5'-region, and a tailing signal of AAUAAA and poly (A+) with 39 A in 3'-region. The gene was transcribed in human embryo by Northern blot hybridization and assigned to human chromosome 12 by in situ hybridization.
