Sequence comparison of cytosolic domains of hGM Rα, IL –3 Rα, and IL-5 Rα.

Aligned cytosolic sequences of hGM Rα, IL-3 Rα, and the related IL-5 Rα are shown. Amino acids present in all 3 Rα subunits or that are subject to conservative change are shown in bold. Those conserved between species are boxed and those present in 2 α subunits are marked with an asterisk (*). The PIG and KLN sequences of hIL-3 Rα and hGM Rα are indicated by underlining.
