Isolation of two odorant-binding proteins from mouse nasal tissue.
1. Two soluble proteins, with good affinity to tritiated 2-isobutyl-3-methoxypyrazine, have been purified from mouse nasal mucosa. 2. The first protein is a heterodimer with subunits of apparent M(r) 18 and 19 kDa and isoelectric point of 4.9; the second is a monomer of M(r) 21 kDa and isoelectric point of 4.8. 3. The characteristics of these binding proteins are compared with those of the other known OBPs and urinary proteins and their putative role is discussed.
