Hadas Raveh-Amit


Hadas Raveh-Amit graduated with excellence (Summa cum laude) from the Department of Microbiology and Immunology, Ben-Gurion University of the Negev, Beer Sheva, Israel. Her studies were supervised by Prof. Etta Livneh and focused on the translational control mechanism of Protein Kinase C family by regulatory elements located in the 5'-Untranslated Region. After receiving her Master, the candidate has continued her studies in the laboratory of Prof. Etta Livneh and is now at the final stage of her Phd. Hadas joined Biotalentum Ltd. located in Gödöllő, Hungary on August 2011 as a postdoctoral fellow.

Project Topic

The role of the intrinsically disordered protein RYBP in neural and cardiac differentiation of pluripotent stem cells.

Project Description
Protein disorder reaches high proportions in the proteomes of higher eukaryotes. In the human proteome, for example, about 12% of proteins are fully disordered, and 50% of proteins contain at least one long disordered region. The function of intrinsically disordered proteins (IDPs) is strongly associated with key cellular functions, such as signalling, regulation of the cell-cycle and transcription. In this study, we will focus on the role of IDPs in an embryonic stem (ES) cell based system. The RING1 and YY1 binding protein (RYBP) will be used as a model to study the role of this previously described IDP in ES differentiation. RYBP, a member of the polycomb group (PcG), is a transcriptional repressor and not surprisingly primarily localized in the nucleus. It was shown to interact with numerous partners and therefore form multiple complexes (such as with the BCOR complex, the MDM2 protein and ubiquitinated proteins). Interestingly, it was proposed that RYBP participates in a complex transcriptional regulatory network in mouse ES, however, its functions remain largely unknown. Therefore, we will examine the role of RYBP in neural and cardiac differentiation in an embryonic stem (ES) cell based system. For this purpose, we will use in vitro differentiation assays available at Biotalentum Ltd. Hopefully, these studies will open up important regulatory possibilities in neuronal lineage and cardiac development.
