    Streszczenie angielskie: Background: The Saccharomyces cerevisiae strain, 22574d, lacks gamma amino butyric acid (GABA) transport activity and cannot grow on this amino acid as sole nitrogen source. Both transport of and growth on this amino acid are restored when the yeast is transformed iwht a form of mouse gamma actin containing an extended C-terminal sequence (mç-A). The nature of the mutation in the transporter as well as the complementation mode are addressed. Materia/Methods: The cDNA sequence of the mutated transporter was achieved using reverse transcription, 3'- Race and cloning. For detection, Northern blotting and labeling with 32-P were used. THe putative ability of the transporter to interact with gamma actin in vivo was examined by following the interaction in vitro of synthetic peptides corresponding to the C-termini of the gamma actin and the transporter. Resutls: Up to codon 394 the mutated an native transporters are identical. At the 3' end, the mutant is by extended by 32 codons from the delta region of a Tyl transposon, giving an open reading frame of 426 codons, and a predicted structure of 9 of the 11 transmembrane domains. Peptides correspoding to the carboxy terminal regions of the truncated transporter and the elongated species of gamma actin show the potential to interact in vitro. Conclusion: The mutated GABA transporter mRNA contains an insert from the delta region of a Tyl transposon. This insertion allows expression of a transporter capable of itneracting with elongated gamma actin to rehabilitate the transporter.
