1.A.69.5.2 Odorant Receptor 4, OR4 or GPROR4, of 406 aas and 7 or 8 TMSs; if 8, the C-terminal TMS may not be a TMS. This odorant receptor specifically recognizes the human odorant
sulcatone (6-methylhept-5-en-2-onesul), a volatile odorant emitted at
uniquely high levels in humans, thereby playing a key role in mosquito's
preference in biting human compared to other animals (McBride et al. 2014). Aedes aegypti is a vector for viruses that spread diseases like dengue, Zika and Chikungunya. Tiwari and Sowdhamini 2023 have modeled the full-length structure of OR4 and the ORco of A. aegypti.
