Localization of an RNA-binding domain in the nucleocapsid protein of the coronavirus mouse hepatitis virus 1992 .txt text/plain 5901 279 57 The RNase sensitivity of the ability of N protein to migrate into nondenaturing gels was not due to possible contaminating protease activity in the RNase preparations, since the same RNase-treated samples of translated N 148 P.S. Masters protein showed no degradation when analyzed by SDS-PAGE (Fig. 3, lanes an, lower) . Since the N mRNAs synthesized from the transcription vectors shown in Fig. 1 contained this portion of the leader sequence, it seemed possible that the N-RNA complex observed in nondenaturing PAGE was that of translated N protein binding to its own mRNA. That the observed complex was not due to translated N protein binding to the leader portion of its own mRNA was also supported by the observation that full-length N protein translated from a construct in which the MHV leader sequence was entirely deleted was also able to migrate into nondenaturing gels (data not shown). ./cache/cord-341342-kyavg4vu.txt ./txt/cord-341342-kyavg4vu.txt
