Two splice variants of the DsMEK1 mitogen-activated protein kinase kinase (MAPKK) are involved in salt stress regulation in Dunaliella salina in different ways

摘要

Characteristics of alternatively spliced variants of DsMEK1. a Detection of alternative transcripts of DsMEK1 by PCR analysis. M, 2000+ DNA size markers. X1 and X2 indicate the DsMEK1-X1, and DsMEK1-X2 transcripts, respectively. b Genomic structures of alternatively spliced variants. Black lines indicate the introns and red boxes represent exons. c Domain structures of protein splice variants (protein kinase domain, active site, and nuclear transport factor 2) indicated by the colour boxes. Coloured boxes mark the different regions in the proteins
