BUD13 Homolog (BUD13)

BUD13 Belongs to the CWC26 family.A spliceosome is a complex of snRNA and protein subunits that removes introns from a transcribed pre-mRNA (hnRNA) segment. This process is generally referred to as splicing.Each spliceosome is composed of five small nuclear ribonucleoproteins snRNPs, (pronounced "snurps") and a range of non-snRNP associated protein factors.The snRNPs that make up the nuclear spliceosome are named U1, U2, U4, U5, and U6, and participate in several RNA-RNA and RNA-protein interactions. The RNA component of the snRNP is rich in uridine (the nucleoside analog of the uracil nucleotide).The canonical assembly of the spliceosome occurs anew on each hnRNA (pre-mRNA). The hnRNA contains specific sequence elements that are recognized and utilized during spliceosome assembly.
