mir-24 microRNA precursor family
The miR-24 microRNA precursor is a small non-coding RNA molecule that regulates gene expression. microRNAs are transcribed as ~70 nucleotide precursors and subsequently processed by the Dicer enzyme to give a mature ~22 nucleotide product. In this case the mature sequence comes from the 3' arm of the precursor. The mature products are thought to have regulatory roles through complementarity to mRNA. miR-24 has been identified in human and mouse.[1][2]
Targets of miR-24
- Lal et al. suggested that miR-24 suppresses the tumor suppressor p16(INK4a).[3]
- Wang et al.. have shown that miR-24 reduces the mRNA and protein levels of human ALK4 by targeting the 3'-untranslated region of mRNA.[4]
- Mishra et al. suggest that miR-24 targets the DHFR gene.[5]
