According to the book: Ionotropic receptors have 5 subunits which surround a central ion channel. Each subunit has a similar structure, with 4 membrane-spanning segments. (M1-M4). The M2 segment lines the pore.Source(s): Animal Physiology - Hill, Wyse, Anderson. Chp. 12, Table 12.3 and Figure 12.16.
