Role of the RNA recognition motif of the E1B 55 kDa protein in the adenovirus type 5 infectious cycle.

Abstract excerpt

Although the adenovirus type 5 (Ad5) E1B 55 kDa protein can bind to RNA in vitro, no UV-light-induced crosslinking of this E1B protein to RNA could be detected in infected cells, under conditions in which RNA binding by a known viral RNA-binding protein (the L4 100 kDa protein) was observed readily. Substitution mutations, including substitutions reported to inhibit RNA binding in vitro, did not impair synthesis...
