During his PhD studies, Ervinas Gaidamauskas researched the proteins pregnancy-associated plasma protein-A (PAPP-A) and its homologue PAPP-A2 in vitro.

As suggested by its name, PAPP-A plays an important role in pregnancy and fetal development. Additionally, recent studies indicate a newly recognised role for PAPP-A in ageing and in the development of age-related disease. PAPP-A is a secreted metalloproteinase that cleaves insulin-like growth factor binding proteins (IGFBPs).

Ervinas Gaidamauskas studied the mechanism of IGF-modulated proteolysis of IGFBPs by PAPP-A and the structural determinants for cleavage. Using small-angle X-ray scattering (SAXS), he also analysed the intermodular structural organisation of the C-terminal domain of PAPP-A involved in substrate binding.

Detailed knowledge of interactions between PAPP-A and its substrates is required to understand the modulatory role of PAPP-A on IGF receptor stimulation.
