Any process involved in the conversion of a primary mRNA transcript into one or more mature mRNA(s) prior to translation into polypeptide. Any process by which a pre-mRNA or mRNA molecule is cleaved at specific sites or in a regulated manner. Any process involved in the conversion of one or more primary RNA transcripts into one or more mature RNA molecules. The process by 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. Some protein processing events may be included when they are required to form an active form of a product from an inactive precursor form. The cellular chemical reactions and pathways involving RNA, ribonucleic acid, one of the two main type of nucleic acid, consisting of a long, unbranched macromolecule formed from ribonucleotides joined in 3',5'-phosphodiester linkage. The chemical reactions and pathways involving mRNA, messenger RNA, which is responsible for carrying the coded genetic 'message', transcribed from DNA, to sites of protein assembly at the ribosomes. The conversion of a primary mRNA transcript containing more than one complete protein-coding region into individual mature mRNA molecules. Any process involved in forming the mature 3' end of an mRNA molecule. Addition of the 7-methylguanosine cap to the 5' end of a nascent messenger RNA transcript. Steps involved in processing precursor RNAs arising from transcription of operons in the chloroplast genome into mature mRNAs. Any process that modulates the frequency, rate or extent of mRNA processing, those processes involved in the conversion of a primary mRNA transcript into a mature mRNA prior to its translation into polypeptide. Any process that stops, prevents or reduces the frequency, rate or extent of mRNA processing. The spliceosome-independent cleavage and ligation of the mRNA encoding a UFP-specific transcription factor to remove a single intron, thereby increasing both the translational efficiency of the processed mRNA and the activity of the protein it encodes. Any process that activates or increases the frequency, rate or extent of mRNA processing. The joining together of exons from one or more primary transcripts of nuclear messenger RNA (mRNA) and the excision of intron sequences, via a spliceosomal mechanism, so that mRNA consisting only of the joined exons is produced. Splicing of mRNA substrates via recognition of the folded RNA structure that brings the 5' and 3' splice sites into proximity and cleavage of the RNA at both the 3' and 5' splice sites by an endonucleolytic mechanism, followed by ligation of the exons.
