Cezar Martins de Sá, Brazilian molecular geneticist (1948 – Brasilia 25 January 2011)

Co-discovered the prosome, a small RNP complex

With H.P. Schmid, O. Akhayat, F. Puvion, K. Koehler & K. Scherrer. The prosome: an ubiquitous morphological distinct RNP particle associated with repressed mRNPs and containing specific ScRNA and a characteristic set of proteins. EMBO J. 3(1):29-34, 1984
