Identification and characterization of cap-binding proteins from yeast.

C Goyer1, M Altmann, H Trachsel, N Sonenberg.   

Abstract

Photochemical cross-linking of Saccharomyces cerevisiae ribosomal salt wash preparations to cap-labeled mRNA reveals, in addition to the previously characterized 24-kDa cap-binding protein (eIF-4E), the presence of two novel cap-binding proteins (CBPs) of apparent molecular masses of 96 and 150 kDa. Cross-linking of the 96-kDa CBP was found to occur spontaneously without UV light induction. Based on the ATP/Mg2+ requirements, the three CBPs can be subdivided into two classes: 1) ATP/Mg2+ independent (24- and 150 kDa) and 2) Mg2+ dependent (96 kDa). The co-purification of the 24- and 150-kDa CBPs through several different chromatographic steps is consistent with the existence of a yeast CBP complex, possibly analogous to mammalian eIF-4F.
