Summary
Caution, this is an AI generated summary based on literature. This may have errors. ?

MIR135A2 is a microRNA implicated in the modulation of midbrain development through the repression of the gene Lmx1b [PMC3861205]. Research involving luciferase assays in HEK293 cells demonstrated that MIR135A2 could repress a reporter construct containing a segment of the Lmx1b 3′ untranslated region (UTR) [PMC3861205]. However, this repression did not occur when mutations were introduced into the MIR135A2 binding sites within the Lmx1b 3′UTR, underscoring the specificity of MIR135A2's interaction with its target [PMC3861205]. These findings suggest that MIR135A2 has a functional role in midbrain development by directly targeting and regulating Lmx1b expression [PMC3861205].
