Alf. Mui et A. Miyajima, INTERLEUKIN-3 AND GRANULOCYTE-MACROPHAGE COLONY-STIMULATING FACTOR-RECEPTOR SIGNAL-TRANSDUCTION, Proceedings of the Society for Experimental Biology and Medicine, 206(3), 1994, pp. 284-288
The cytokines, interleukin-3 (IL-3) and granulocyte-macrophage colony-
stimulating factor (GM CSF), share many similar activities on cells of
the hemopoietic system. Cloning of the receptors for IL-3 and GM-CSF
revealed that these two cytokines utilize receptors consisting of a li
gand-specific alpha unit and a beta subunit which is shared. Neither s
ubunit contains intrinsic tyrosine kinase activity, but deletion analy
sis of the beta subunit cytoplasmic domain has defined certain regions
which are important for signal transduction.
