Gene Family: Major spliceosome

Also known as : "U2 dependent spliceosome"

Major Spliceosome:: A spliceosome is a large and complex molecular machine found primarily within the splicing speckles of the cell nucleus of eukaryotic cells. The spliceosome is assembled from snRNAs and protein complexes. The spliceosome removes introns from a transcribed pre-mRNA, a type of primary transcript. This process is generally referred to as splicing. Only eukaryotes have spliceosomes and some organisms have a second spliceosome, the minor spliceosome. [Source: Wikipedia]

The spliceosomal complexes A, B, Bact, C and P are intermediates formed during the different steps of spliceosome mediated mRNA splicing.
