Seed match plus local RNA structure jointly determine lncRNA-0021 binding to mm…

Mechanistic description

The most likely explanation is a two-factor recognition mechanism: a canonical miRNA seed-complementary site in lncRNA-0021 provides initial specificity, while a favorable local secondary structure or central pairing pattern raises affinity enough to distinguish mmu-miR-6361 from other seed-sharing candidates. This explains why seed complementarity is necessary but not by itself sufficient for selective binding.

Evidence for (3)

Seed pairing is the dominant first-pass determinant of miRNA target recognition, making it a necessary component of any direct lncRNA-miRNA interaction model.

PMID:28642336
Central-region pairing and target-site architecture can differentiate functional from non-functional miRNA interactions beyond seed matching alone.

PMID:26299336
Structured lncRNA regions are enriched for miRNA interactions in brain-relevant contexts, supporting a structure-assisted binding model.

PMID:30559488

Evidence against (2)

Seed matches are common and often non-functional, so seed complementarity alone has poor positive predictive value for true ceRNA behavior.

PMID:28642336
The source paper confirms direct binding in a related context but does not establish that lncRNA-0021, rather than lncRNA-9969, is the actual transcript involved.
