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

MIR127 is a microRNA that functions as a repressor for RTL1 expression through the RNAi mechanism [PMC3469456]. The expression of RTL1 is significantly elevated in mice with the targeted deletion of the maternally derived IG-DMR, similar to the elevation observed in mice with increased RTL1 expression due to MIR127 repression [PMC3469456]. The increased expression of RTL1 is attributed to the repressor function of MIR127, which is encoded by RTL1as [PMC3469456]. It has been suggested that MIR127, along with other microRNAs such as miR433, regulates the expression of RTL1 through RNAi mechanism [PMC3469456]. Additionally, it has been proposed that DIO3, a gene involved in thyroid hormone metabolism, may not be solely expressed from the paternally inherited allele and may undergo partial imprinting or complete imprinting escape [PMC3469456]. Furthermore, MIR127 has been found to regulate IL-6 and TNF-α cytokine release by macrophages in lung inflammation by targeting IgG FcγRI (CD64) [PMC5247697]. Overall, MIR127 plays a crucial role in regulating gene expression and cytokine release through its repressor function.

Annotation confidence High
Do you think this miRNA is real?
Comments
This miRNA sequence is predicted based on homology to a verified miRNA from mouse [1]. The expression of this miRNA was later confirmed by cloning in human cells [2,3].
