Summary
This study introduces LPI-BNPRA, a computational method to predict long non-coding RNA (lncRNA)-protein interactions. This approach offers a time-saving and cost-effective alternative to experimental methods for uncovering these crucial biological relationships.
Area of Science:
- Biotechnology
- Genomics
- Bioinformatics
Background:
- Non-coding RNAs (ncRNAs) are vital in biological processes like cell differentiation and disease.
- Long non-coding RNAs (lncRNAs) constitute the majority of ncRNAs and exert functions via RNA-binding proteins.
- Experimental validation of lncRNA-protein interactions is costly and time-consuming.
Purpose of the Study:
- To develop a novel computational method for predicting lncRNA-protein interactions.
- To provide a time-saving and cost-effective approach for identifying potential lncRNA-protein relationships.
Main Methods:
- Proposed a semi-supervised method named LPI-BNPRA (lncRNA-protein interaction-bipartite network projection recommended algorithm).
- Utilized lncRNA similarity matrix, protein similarity matrix, and lncRNA-protein interaction matrix.
- Employed leave-one-out cross-validation for performance evaluation.
Main Results:
- LPI-BNPRA achieved high-confidence results with an AUC of 0.8754 and AUPR of 0.6283.
- Outperformed three previous computational methods in prediction accuracy.
- Case studies on the Mus musculus dataset confirmed the reliability of the approach.
Conclusions:
- LPI-BNPRA is a reliable computational tool for predicting lncRNA-protein interactions.
- The method can significantly aid biomedical research by efficiently identifying these interactions.
- Facilitates a deeper understanding of lncRNA functions in biological processes and diseases.

An organism can have thousands of different proteins, and these proteins must cooperate to ensure the health of an organism. Proteins bind to other proteins and form complexes to carry out their functions. Many proteins interact with multiple other proteins creating a complex network of protein interactions.
These interactions can be represented through maps depicting protein-protein interaction networks, represented as nodes and edges. Nodes are circles that are representative of a protein,...

Proteins that regulate transcription can do so either via direct contact with RNA Polymerase or through indirect interactions facilitated by adaptors, mediators, histone-modifying proteins, and nucleosome remodelers. Direct interactions to activate transcription is seen in bacteria as well as in some eukaryotic genes. In these cases, upstream activation sequences are adjacent to the promoters, and the activator proteins interact directly with the transcriptional machinery. For example, in...

9.9K
In humans, more than 80% of the genome gets transcribed. However, only around 2% of the genome codes for proteins. The remaining part produces non-coding RNAs which includes ribosomal RNAs, transfer RNAs, telomerase RNAs, and regulatory RNAs, among other types. A large number of regulatory non-coding RNAs have been classified into two groups depending upon their length – small non-coding RNAs, such as microRNA, which are less than 200 nucleotides in length, and long non-coding RNA...

60.6K
Splicing is the process by which eukaryotic RNA is edited before its translation into protein. The RNA strand transcribed from eukaryotic DNA is called the primary transcript. The primary transcripts that become mRNAs are called precursor messenger RNAs (pre-mRNAs). Eukaryotic pre-mRNA contains alternating sequences of exons and introns. Exons are nucleotide sequences that code for proteins, whereas introns are the non-coding regions. In RNA splicing, introns are removed and exons are bonded...
