Proteins interacting with RNA structures at the 3' non-translated region (3'NTR) of picornaviruses are probably important during viral RNA replication. We have shown previously that a dominant cellular cytoplasmic protein of 38 kDa (p38) interacts with the 3'NTR and upstream regions of the hepatitis A virus (HAV) RNA (Kusov et al., J Virol 70, 18901897, 1996). Immunological and biochemical analyses of p38 have indicated that it is identical to GAPDH, which has previously been described as modulating translational regulation of the HAV RNA by interacting with the 5'NTR (Schultz et al., J Biol Chem 271, 1413414142, 1996). Three separate binding regions for GAPDH in the 3'NTR and in the upstream 3D polymerase-coding region were identified. Structural analysis of these RNA regions by computer modelling and direct enzymatic cleavage suggested the presence of several AU-rich stemloop structures having the potential for tertiary interactions. Binding of GAPDH to these structures was confirmed by RNA footprint analysis and resulted in the loss of double-stranded RNA regions. A different panel of RNA binding proteins (p28, p41 and p65) was detected in the ribosomal fractions of several cell lines (BSC-1, FRhK-4 and HeLa), whereas RNA binding of the GAPDH that was also present in these fractions was only marginal or absent.
