Identification of a human cDNA encoding a novel protein structurally related to the yeast membrane-associated metalloprotease, Ste24p.

Recently, a novel membrane-associated metalloprotease, designated Ste24p, has been identified in Saccharomyces cerevisiae [K. Fujimura-Kamada, F.J. Nouvet, S. Michaelis, J. Cell Biol. 27 (1997) 271-285]. We cloned a human brain cDNA encoding a protein homologous to Ste24p (designated Hs Ste24p). The predicted 475-amino acid product of its open reading frame exhibited 62% similarity to Ste24p, and contained a zinc metalloprotease motif (HEXXH) and multiple predicted membrane spans. Northern blot analysis showed that this gene was expressed in most tissues. Immunofluorescence analysis of epitope-tagged Hs Ste24p constructs suggested that it is localized in the ER and possibly also in the Golgi compartment. A search of the expression sequence tag database identified a fragment of DNA encoding a segment homologous to the segment of Hs Ste24p containing the HEXXH motif in insects and nematodes. Thus, Hs Ste24p could be a member of a new family of Ste24p-like membrane-associated metalloproteases which are widely conserved in eukaryotes.[1]
