Synthesized as a proprotein, LEKTI is rapidly cleaved intracellularly, thus generating a number of potentially bioactive fragments that are secreted. Here, we show that SPINK5 generates three classes of transcripts encoding three different LEKTI isoforms, which differ in their C-terminal portion. In addition to the previously described 15 domain isoform, SPINK5 encodes a shorter LEKTI isoform composed of only the first 13 domains, as well as a longer isoform carrying a 30-amino-acid residue insertion between the 13th and 14th inhibitory domains. We demonstrate that variable amounts of SPINK5 alternative transcripts are detected in all SPINK5 transcriptionally active tissues. Finally, we show that in differentiated cultured human keratinocytes all SPINK5 alternative transcripts are translated into protein and that the LEKTI precursors generate distinct secreted C-terminal proteolytic fragments from a similar cleavage site. Since several data indicate a biological role for the pro-LEKTI-cleaved polypeptides, we hypothesize that the alternative processing of the SPINK5 pre-messenger RNA represents an additional mechanism to further increase the structural and functional diversity of the LEKTI bioactive fragments."xsd:string |
