EOG8HTC6W	GO:0000398	1/83	mRNA splicing, via spliceosome	biological_process	"The joining together of exons from one or more primary transcripts of messenger RNA (mRNA) and the excision of intron sequences, via a spliceosomal mechanism, so that mRNA consisting only of the joined exons is produced." [GOC:krc, ISBN:0198506732, ISBN:0879695897]
EOG8HTC6W	GO:0046854	1/83	phosphatidylinositol phosphorylation	biological_process	"The process of introducing one or more phosphate groups into a phosphatidylinositol, any glycerophosphoinositol having one phosphatidyl group esterified to one of the hydroxy groups of inositol." [ISBN:0198506732]
EOG8HTC6W	GO:0071011	1/83	precatalytic spliceosome	cellular_component	"A spliceosomal complex that is formed by the recruitment of a preassembled U5-containing tri-snRNP to the prespliceosome. Although all 5 snRNPs are present, the precatalytic spliceosome is catalytically inactive. The precatalytic spliceosome includes many proteins in addition to those found in the associated snRNPs."
