Isolation and characterization of the gene encoding the type 5 mouse (Mus musculus) somatostatin receptor (msst5).

We have isolated and determined the nucleotide sequence of the gene for the fifth mouse somatostatin receptor (msst5). The gene can encode a protein of 363 amino acid residues (aa). The deduced aa sequence of msst5 has 97 and 81% identity to the rat and human sst5 respectively, while it has lower identities with the four other mouse sst(n)s (msst1 -- 48%, msst2 -- 55%, msst3 -- 56%, and msst4 -- 52%). We show that msst5 is expressed in brain but not in liver, heart, spleen, or kidney of the adult mouse.
