    U2 SMALL NUCLEAR RIBONUCLEOPROTEIN PARTICLE -
    The U2 small nuclear ribonucleoprotein particle (U2 snRNP) contains U2 snRNA. It is recruited to the spliceosome after U1 snRNP and forms a stable interaction with the branch site and 3' splice site in pre-mRNA. (Adapted from PMID:23829528 and PMID:21441581).
    SPLICEOSOME COMPLEX A -
    Nuclear pre-mRNA splicing is catalyzed by the spliceosome which assembles in a step-wise manner. Complex A, the pre-spliceosome, is composed of U1 and U2 snRNPs and proteins involved in recognition of the 5' splice site and branch point. (Adapted from PMID:24452469 and PMID:23118483).
    SPLICEOSOME COMPLEX B -
    Nuclear pre-mRNA splicing is catalyzed by the spliceosome which assembles in a step-wise manner. After the assembly of complex A on pre-mRNA, the U4-U6 and U5 snRNPs are recruited as a preassembled tri-snRNP to form complex B. U5 snRNP binds exons at the 5' site. (Adapted from PMID:24452469 and PMID:23118483).
    SPLICEOSOME COMPLEX C -
    Nuclear pre-mRNA splicing is catalyzed by the spliceosome which assembles in a step-wise manner. Complex B undergoes a number of structural rearrangements and U4 and U1 snRNPs dissociate to generate complex C, the catalytic spliceosome. (Adapted from PMID:24452469 and PMID:23118483).
    SPLICEOSOME COMPLEX P -
    Nuclear pre-mRNA splicing is catalyzed by the spliceosome which assembles in a step-wise manner. Complex P, the post-spliceosomal complex, is formed after the catalytic removal of the intron by complex C. Complex P contains the lariat intron and spliced exons. (Adapted from PMID:24452469 and PMID:23118483).
