Function

Ubiquitin-protein ligase which is a core component of several complexes mainly involved pre-mRNA splicing and DNA repair. Required for pre-mRNA splicing as component of the spliceosome (PubMed:28502770, PubMed:28076346, PubMed:29360106, PubMed:29301961, PubMed:30705154). Core component of the PRP19C/Prp19 complex/NTC/Nineteen complex which is part of the spliceosome and participates in its assembly, its remodeling and is required for its activity. During assembly of the spliceosome, mediates 'Lys-63'-linked polyubiquitination of the U4 spliceosomal protein PRPF3. Ubiquitination of PRPF3 allows its recognition by the U5 component PRPF8 and stabilizes the U4/U5/U6 tri-snRNP spliceosomal complex (PubMed:20595234). Recruited to RNA polymerase II C-terminal domain (CTD) and the pre-mRNA, it may also couple the transcriptional and spliceosomal machineries (PubMed:21536736). The XAB2 complex, which contains PRPF19, is also involved in pre-mRNA splicing, transcription and transcription-coupled repair (PubMed:17981804). Beside its role in pre-mRNA splicing PRPF19, as part of the PRP19-CDC5L complex, plays a role in the DNA damage response/DDR. It is recruited to the sites of DNA damage by the RPA complex where PRPF19 directly ubiquitinates RPA1 and RPA2. 'Lys-63'-linked polyubiquitination of the RPA complex allows the recruitment of the ATR-ATRIP complex and the activation of ATR, a master regulator of the DNA damage response (PubMed:24332808). May also play a role in DNA double-strand break (DSB) repair by recruiting the repair factor SETMAR to altered DNA (PubMed:18263876). As part of the PSO4 complex may also be involved in the DNA interstrand cross-links/ICLs repair process (PubMed:16223718). In addition, may also mediate 'Lys-48'-linked polyubiquitination of substrates and play a role in proteasomal degradation (PubMed:11435423). May play a role in the biogenesis of lipid droplets (By similarity). May play a role in neural differentiation possibly through its function as part of the spliceosome (By similarity).

Activity summary

The PRP19 protein also known as Pre-mRNA Processing factor 19 weighs approximately 55 kDa. This protein plays a role in the splicing of pre-mRNA by functioning as part of the spliceosome complex. PRP19 is expressed in many tissues and cells which reflects its important role in RNA processing. It is not confined to a specific type of tissue indicating its broad relevance in cellular processes. Mechanically PRP19 acts by enhancing the efficiency of splicing ensuring that mRNA molecules are properly matured for translation.

Biological function summary

PRP19 engages in multiple processes beyond its initial splicing role. It forms part of the NTC complex which is critical for the activation of the spliceosome. This complex includes other key proteins essential for RNA splicing transition phases. Additionally PRP19 contributes to DNA repair mechanisms playing a part in maintaining genomic integrity under stress conditions. Its role in these processes demonstrates its versatile functionality in cell homeostasis and response to damage.

Pathways

Experts recognize PRP19's involvement in the mRNA processing and DNA damage response pathways. These pathways are key to understanding how cells manage genetic information and react to physiological challenges. PRP19 interacts with other proteins such as CDC5L and PLRG1 within these pathways illustrating its interconnected role in cellular regulation. These associations underline how PRP19 integrates into critical networks that balance gene expression and genome stability.

Associated diseases and disorders

Researchers have linked PRP19 to cancer and neurodegenerative disorders. In cancer abnormal PRP19 function may contribute to unchecked cell growth by impacting mRNA splicing and DNA repair. In neurodegenerative diseases its dysfunction might influence neuron survival through defective RNA processing. The relationship of PRP19 with proteins like BRCA1 in the context of cancer further highlights its significance in disease mechanisms. As such PRP19 serves as a potential target for therapeutic exploration.
