Popis: Objective: To clone the human counterpart of rat ZA73, EST cloned from rat tracheal epithelial (RTE) neoplastic transformed cell model induced by (a-particles radiation by using mRNA differential display. Methods: According to the sequence of rat ZA73, a probe was biotin-labeled to screen human cDNA library, and then the gene sequence was extended by RACE (rapid amplification of cDNA ends). Result: Human gene HRNT-1 (GenBank Accession Number: AF223393) is 4.256 kb in length, with an ORF located in the region between 254 and 3013 bp. 5′ UTS (untranslated sequences) is 253 bp, 3′ UTS is 1243 bp. Conclusion: The combination of cDNA library screening with biotin-labeled probes and RACE is an effective method to clone full-length cDNA, especially for sequences longer than 2 kb.
