Communicated with Uta Jappe a number of times. The publication in JACI 2015 is quite good (Petersen). However, the EST predicts a longer protein and the MW in the publication suggests that a longer sequence of ~ 8kDa is present in the extract. The proteins are NOT very soluble in PBS and most extracts miss them.
