Our main research focus is on a group of proteins comprising the hepatoma-derived growth factor (HDGF), the HDGF-related proteins 1 - 4 (HRP-1-4) and the lens epithelium-derived growth factor (LEDGF). All members belong to a growing number of proteins containing the PWWP-domain which is located in a highly conserved 100 amino acids spanning N-terminal region, called the hath-region (homologues to the amino-terminus of HDGF). With the aid of nuclear localization signals (NLS) the proteins are predominantely located to the nucleus. Interestingly, very little is known about the exact functions of most of the members within the cell and especially about the functions in different cell types or tissues. Growth promoting activity, unknown routes of secretion and internalization are some of the characteristics which have been identified. Furthermore, HDGF and probably other HRPs seem to play an important role in different forms of cancer.

Using a variety of biochemical and cell biology methods in close cooperation with different working groups, we are investigating protein/protein interactions, post-translational modifications (SUMOylation, Phosphorylation or O-GlnAc), oxidative stress response, subcellular trafficing etc. to get a better understanding of the functions and the functional regulations of these proteins within the cell.
