title: [Brain-specific sequence Hfb1 is part of the 3'-untranslated region of the human complexin 2 gene: new data from in vitro and in silico experiments].
abstract: A genomic clone hybridizing with brain-specific sequence Hfb1 was isolated from a chromosome 5 consmid library. Hfb1 proved to correspond to a new gene exon which codes for a large 3'-untranslated region of the mRNA for synaptic protein complexin 2. Together with the 985-nt Hfb1 cDNA (EMBL Y15167) isolated previously from a cDNA library of the frontal cerebral cortex, the primary structure was established for genomic clone Ghfb sized more than 4 kb. A GenBank search revealed complete identity of the 5' end of Ghfb and the 3'-untranslated region (878-933) of the human complexin 2 mRNA. Large transcripts with the 5' end corresponding to the complexin 2 mRNA and the 3' end to Ghfb were detected in total mRNA of the human brain by means of RT-PCR. The size of the 3'-untranslated region of the human complexin 2 mRNA was estimated at 4 kb.
