To Dr. Hallak from CIQUIBIC
The Dr. Marta Hallak, Principal Investigator of CONICET and Associate Professor in the Department. Biological-Chemical CIQUIBIC, It has been appointed by the International Brain Research Organization (IBRO) as Senior Director of Grants. Dr.. Hallak IBRO has contributed over the years, first serving as coordinator Regional Committee for Latin America (IBRO-LARC) and then as coordinator Committee Scholarships and travel grants. With this appointment, IBRO has recognized the work, the experience and commitment of Dr.. Hallak to the Organization. In his new role, Dr.. Hallak is a member of the Executive Committee of IBRO, providing vision and advice regarding scholarship programs and grants.
Dr.. Hallak investigates the effect of our Center posttranslational modifications in the biological function of proteins. En particular, its working group has focused on the study of protein posttranslational arginylation, event involved in several cellular processes, including cell migration, cardiovascular development, angiogenesis, thrombosis and espermatogénensis. This modification is catalyzed by the enzyme arginiltransferasa (ATE1) transferring an arginine residue Arg-tRNA of the amino terminus of the proteins or peptides. In his group they have identified several proteins that act as substrates and are currently investigating the functional role in the nervous system.
Dr. Marta Hallak, Principal Researcher of CONICET and Associate Professor at the Department of Biological Chemistry-CIQUIBIC, has been named Senior Director of Grants by the International Brain Research Organization (IBRO) . At IBRO, Dr. Hallak has served as Chair of the IBRO Latin America Regional Committee (IBRO-LARC) and, most recently, Chair of the IBRO Fellowships & Travel Grants Committee. IBRO has recognized Dr. Hallak’s work, experience and commitment to the Organization, naming her as the first Senior Editor of Grants. In her new role, Dr. Hallak will be a member of the Executive Committee of IBRO, providing her insights and advice regarding IBRO fellowship and grant programs.
Dr. Hallak investigates in our Center the effect of post-translational modifications on the biological function of proteins. In particular, her research interest is focused on the study of protein posttranslational arginylation, event that is involved in several cellular processes including cell migration, cardiovascular development, angiogenesis, thrombosis and spermatogenesis. This reaction is catalyzed by the enzyme arginiltransferase (ATE1) which transfers an arginine-tRNA Arg residue from the amino terminus of proteins or peptides. In her group, they have identified several proteins that act as substrates and currently, they are investigating the functional roles played by this modificiation in the functioning of the nervous system.
