Leucine-rich repeat protein PRAME: expression, potential functions and clinical implications for leukaemia

Mol Cancer. 2010 Aug 27:9:226. doi: 10.1186/1476-4598-9-226.


PRAME/MAPE/OIP4 is a germinal tissue-specific gene that is also expressed at high levels in haematological malignancies and solid tumours. The physiological functions of PRAME in normal and tumour cells are unknown, although a role in the regulation of retinoic acid signalling has been proposed. Sequence homology and structural predictions suggest that PRAME is related to the leucine-rich repeat (LRR) family of proteins, which have diverse functions. Here we review the current knowledge of the structure/function of PRAME and its relevance in leukaemia.
