Abstract: The effect of repressors on ion channel gene expression was studied.The hKv4.3 promoter and the sequence (+ 2-+ 160, S160) of 5'-UTR of the hKv4.3 gene was cloned into the pβ-gal-Basic vector.The transient expression of the pβ-gal vector and the analysis of the relative activity of β-galactosidase were carried out.The analysis of the mRNA level was carried out with the RT-PCR method.S160 could intensively repress the expression of the hKv4.3 gene with position-specificity.The level of mRNA did not alter obviously.A repressor(S160), in 5'-UTR of the hKv4.3 gene was found and its repression to gene expression may play a role in the post-transcription process.

Key words: hKv4.3 gene, Repressor
