GO:0000166,MF,"nucleotide binding","Interacting selectively and non-covalently with a nucleotide, any compound consisting of a nucleoside that is esterified with (ortho)phosphate or an oligophosphate at any hydroxyl group on the ribose or deoxyribose.",IEA
GO:0000398,BP,"mRNA splicing, via spliceosome","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.",IGI
GO:0003723,MF,"RNA binding","Interacting selectively and non-covalently with an RNA molecule or a portion thereof.",IEA
GO:0005515,MF,"protein binding","Interacting selectively and non-covalently with any protein or protein complex (a complex of two or more proteins that may include other nonprotein molecules).",IPI
GO:0005634,CC,nucleus,"A membrane-bounded organelle of eukaryotic cells in which chromosomes are housed and replicated. In most cells, the nucleus contains all of the cell's chromosomes except the organellar chromosomes, and is the site of RNA synthesis and processing. In some species, or in specialized cell types, RNA metabolism or DNA replication may be absent.",IEA
GO:0005654,CC,nucleoplasm,"That part of the nuclear content other than the chromosomes or the nucleolus.",IDA
GO:0005737,CC,cytoplasm,"All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.",IDA
GO:0006396,BP,"RNA processing","Any process involved in the conversion of one or more primary RNA transcripts into one or more mature RNA molecules.",IEA
GO:0008266,MF,"poly(U) RNA binding","Interacting selectively and non-covalently with a sequence of uracil residues in an RNA molecule.",IDA
GO:0008543,BP,"fibroblast growth factor receptor signaling pathway","The series of molecular signals generated as a consequence of a fibroblast growth factor receptor binding to one of its physiological ligands.",TAS
GO:0010467,BP,"gene expression","The process in which a gene's sequence is converted into a mature gene product or products (proteins or RNA). This includes the production of an RNA transcript as well as any processing to produce a mature RNA product or an mRNA (for protein-coding genes) and the translation of that mRNA into protein. Protein maturation is included when required to form an active form of a product from an inactive precursor form.",TAS
GO:0016020,CC,membrane,"A lipid bilayer along with all the proteins and protein complexes embedded in it an attached to it.",IDA
GO:0043484,BP,"regulation of RNA splicing","Any process that modulates the frequency, rate or extent of RNA splicing, the process of removing sections of the primary RNA transcript to remove sequences not present in the mature form of the RNA and joining the remaining sections to form the mature form of the RNA.",IMP
GO:0044822,MF,"poly(A) RNA binding","Interacting non-covalently with a poly(A) RNA, a RNA molecule which has a tail of adenine bases.",IDA
GO:0071013,CC,"catalytic step 2 spliceosome","A spliceosomal complex that contains three snRNPs, including U5, bound to a splicing intermediate in which the first catalytic cleavage of the 5' splice site has occurred. The precise subunit composition differs significantly from that of the catalytic step 1, or activated, spliceosome, and includes many proteins in addition to those found in the associated snRNPs.",IDA
