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:0003729,MF,"mRNA binding","Interacting selectively and non-covalently with messenger RNA (mRNA), an intermediate molecule between DNA and protein. mRNA includes UTR and coding sequences, but does not contain introns.",IBA
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: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:0030529,CC,"intracellular ribonucleoprotein complex","An intracellular macromolecular complex containing both protein and RNA molecules.",IDA
GO:0035770,CC,"ribonucleoprotein granule","A non-membranous macromolecular complex containing proteins and translationally silenced mRNAs. RNA granules contain proteins that control the localization, stability, and translation of their RNA cargo. Different types of RNA granules (RGs) exist, depending on the cell type and cellular conditions.",IDA
GO:0043005,CC,"neuron projection","A prolongation or process extending from a nerve cell, e.g. an axon or dendrite.",IEA
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:0051028,BP,"mRNA transport","The directed movement of mRNA, messenger ribonucleic acid, into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore.",IEA
GO:0051033,MF,"RNA transmembrane transporter activity","Enables the transfer of RNA, ribonucleic acid, from one side of a membrane to the other.",IEA
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
GO:1990124,CC,"messenger ribonucleoprotein complex","A ribonucleoprotein complex containing both protein and messenger RNA (mRNA) molecules.",IEA
