Spliceosome component JANUS fulfills a role of mediator in transcriptional regulation during Arabidopsis development.

Abstract

Spliceosomes are large complexes regulating pre-mRNA processing in eukaryotes. Arabidopsis JANUS encodes a putative subunit of spliceosome`. We recently demonstrated that JANUS plays an essential role during early embryogenesis and root meristem development. Instead of mediating pre-mRNA splicing as a subunit of spliceosome, JANUS regulates the transcription of key genes by recruiting RNA Polymerase II (Pol II). Here, we summarize our latest findings and provide insights into the regulation of JANUS during Arabidopsis development.
