Disulfides 8-17 interleukin 3 Mus musculus 68-81 3263644-5 1988 This shows that in IL-3 a single disulfide bridge, between cysteines 17 and 80, is required for biological activity that approximates physiological levels. Disulfides 33-42 interleukin 3 Mus musculus 19-23 3263644-1 1988 Total chemical synthesis of analog proteins was used to examine the requirement for specific disulfide bridges for the biological activity of interleukin 3 (IL-3), a growth factor that stimulates multiple lineages of hemopoietic cells. Disulfides 93-102 interleukin 3 Mus musculus 142-161 6429132-6 1984 After reduction, labeled PSF had a slightly higher Mr of 32,000, although reduction resulted in loss of 98% of PSF activity, thus suggesting that the integrity of internal disulfide bond(s) was required for activity. Disulfides 172-181 interleukin 3 Mus musculus 25-28 20516062-5 2010 We therefore investigated whether distortion of the domain 1-domain 4 ligand-binding epitope in hbetac and the related mouse receptor, beta(IL-3), could account for the loss of receptor signaling when the domain 1 D-E loop disulfide is disrupted. Disulfides 223-232 interleukin 3 Mus musculus 135-144 20516062-8 2010 Our data are most consistent with a role for the domain 1 D-E loop disulfide of hbetac and beta(IL-3) in maintaining the precise positions of ligand-binding residues necessary for normal high affinity binding and signaling. Disulfides 67-76 interleukin 3 Mus musculus 91-100 19961363-2 2010 Although bacterial expression has been used for the preparation of recombinant mIL-3 for more than 20 years, the resultant cytokine is known to exhibit poor solubility, be prone to aggregation, and may contain mispaired disulfide bonds. Disulfides 220-229 interleukin 3 Mus musculus 79-84 9422786-3 1998 We found that substitution of Cys-86, Cys-91, and Cys-96 in betac but not of Cys-100 or Cys-234 abrogated disulfide-linked IL-3 receptor dimerization. Disulfides 106-115 interleukin 3 Mus musculus 123-127 20174897-6 2010 The mIL-3 construct used in the present study was engineered by eliminating residues 27-32 of the N-terminus (the first 26 residues of the primary sequence of mIL-3 are cleaved in vivo during secretion), the C-terminal 10 residues (157-166), and a disulfide bond between Cys105 and Cys166 that is poorly conserved in orthologue sequences.
