Gene structure, differential exon usage, and expression of the testis long intergenic non-protein coding RNA 1016 in humans reveals isoform-specific roles in controlling biological processes

Project description:Long noncoding RNAs (lncRNAs) have emerged as critical regulators of biological processes. The constant expansion of newly-identified lncRNA genes requires that each one be comprehensively annotated to understand its molecular functions. Here, we describe a detailed characterization of the gene which encodes long intergenic non-protein coding RNA 01016 (LINC01016, a.k.a., LncRNA1195) with a focus on its structure, exon usage, and expression in human and macaque tissues. In this study, we show that it is exclusively conserved among non-human primates, suggesting its recent evolution and is expressed and processed into 12 distinct RNAs in testis, cervix, and uterus tissues. Further, we integrate de novo annotation of expressed LINC01016 transcripts and isoform-dependent gene expression analyses to show that human LINC01016 is a multi-exon gene, processed through differential exon usage with isoform-specific functions. Furthermore, in gynecological cancers, such as cervical squamous cell carcinoma and uterine corpus endometrial carcinoma, LINC01016 is downregulated; however, its higher expression is predictive of relapse-free survival in these cancers. Collectively, these analyses reveal that, unlike coding RNAs, lncRNA genes are tightly regulated and precisely processed to generate isoforms with distinct biological roles in specific tissues.

KIS counteracts PTBP2 and regulates alternative exon usage in neurons

Project description:Alternative RNA splicing is an essential and dynamic process in neuronal differentiation and synapse maturation, and dysregulation of this process has been associated with neurodegenerative diseases. Recent studies have revealed the importance of RNA-binding proteins in the regulation of neuronal splicing programs. However, the molecular mechanisms involved in the control of these splicing regulators are still unclear. Here we show that KIS, a kinase upregulated in the developmental brain, imposes a genome-wide alteration in exon usage during neuronal differentiation. KIS contains a protein-recognition domain common to spliceosomal components and phosphorylates PTBP2, counteracting the role of this splicing factor in exon exclusion. At the molecular level, phosphorylation of unstructured domains within PTBP2 causes its dissociation from two co-regulators, Matrin3 and hnRNPM, and hinders the RNA-binding capability of the complex. Furthermore, KIS and PTBP2 display strong and opposing functional interactions in synaptic spine emergence and maturation. Taken together, our data uncover a post-translational control of splicing regulators that link transcriptional and alternative exon usage programs in neuronal development.
