RESUMO

Despite the potentially important roles of untranslated RNAs in cellular form or function, genes encoding such RNAs have until now received surprisingly little attention. One such gene encodes BC1 RNA, a small non-mRNA that is delivered to dendritic microdomains in neurons. We have now eliminated the BC1 RNA gene in mice. Three independent founder lines were established from separate embryonic stem cells. The mutant mice appeared to be healthy and showed no anatomical or neurological abnormalities. The gross brain morphology was unaltered in such mice, as were the subcellular distributions of two prototypical dendritic mRNAs (encoding MAP2 and CaMKIIα). Due to the relatively recent evolutionary origin of the gene, we expected molecular and behavioral consequences to be subtle. Behavioral analyses, to be reported separately, indicate that the lack of BC1 RNA appears to reduce exploratory activity.
