We have previously shown that L58 in the putative 5th helical region of human
interleukin-6
(
IL-6
) is important for activation of the
IL-6
signal transducer gp130 [de Hon et al. (1995) FEBS Lett. 369, 187-191]. To further explore the importance of individual residues in this region for gp130 activation we have now combined Ala substitutions of residues E52,
S53
, S54, K55, E56, L58 and E60 with other substitutions in
IL-6
, known to affect gp130 activation (Q160E and T163P). The combination mutant protein with L58A completely lost the capacity to induce the proliferation of XG-1 myeloma cells, and could effectively antagonize wild type
IL-6
activity on these cells. Moreover, the data suggest that besides L58, S54 particularly, but also E52,
S53
, K55 and E56 contribute to gp130 activation.
