### miRNAs targeting mRNAs

miRNAs regulate protein gene expression by [interacting with target mRNAs](https://doi.org/10.1016/j.cell.2018.03.006).
These interactions are cataloged in [TarBase](/expert-database/tarbase)
and can be viewed and searched in RNAcentral.

#### Examples

- Browse [human miRNAs with protein targets](/search?q=has_interacting_proteins:"True"%20AND%20TAXONOMY:"9606")
- Browse [mouse miRNAs with protein targets](/search?q=has_interacting_proteins:"True"%20AND%20TAXONOMY:"10090")
- Search for [miRNA-protein interactions identified using HITS-CLIP](/search)

The protein targets are not searchable by default to avoid spurious matches
but can be searched using the special syntax:

- [interacting_protein:"ENSG00000277791"](/search?q=interacting_protein:"ENSG00000277791")
- [evidence_for_interaction:"HITS-CLIP"](/search?q=evidence_for_interaction:"hits-clip")

### miRNAs targeting mRNAs


miRNAs regulate gene expression of protein-coding genes by [interacting with
target mRNAs](https://doi.org/10.1016/j.cell.2018.03.006). Hundreds of
thousands of experimentally supported miRNA:gene pairs  are cataloged in
[TarBase](/expert-database/tarbase) and can be viewed and searched in
RNAcentral.

#### Examples
