HUMAN INSULIN-LIKE GROWTH FACTOR; ESRF DATA
|
OverviewOverview
Human insulin-like growth factors I and II (hIGF-I, hIGF-II) are potent, stimulators of cell and growth processes. They display high sequence, similarity to both the A and B chains of insulin but contain an additional, connecting C-domain, which reflects their secretion without specific, packaging or precursor conversion. IGFs also have an extension at the, C-terminus known as the D-domain. This paper describes four homologous, hIGF-1 structures, obtained from crystals grown in the presence of the, detergent SB12, which reveal additional detail in the C- and D-domains., Two different detergent binding modes observed in the crystals may reflect, different hIGF-I biological properties such as the interaction with IGF, binding proteins and self-aggregation. While the helical core of hIGF-I ... [(full description)]
