Terminal loop-mediated control of microRNA biogenesis

Nila Roy Choudhury et al. Biochem Soc Trans. 2012 Aug.

Abstract

Regulation of miRNA (microRNA) biogenesis shapes the profiles of miRNAs in the living cell, contributing to cell identity and function. Importantly, aberrant miRNA levels have been linked to a variety of human pathological states. In recent years, a number of proteins have been shown to regulate the miRNA biogenesis at the level of Drosha and Dicer cleavage. A large proportion of these factors regulate miRNA production through binding to the TL (terminal loop) regions of miRNA progenitors. In the present paper, we review the current knowledge about pri-miRNA (primary miRNA) and pre-miRNA (precursor miRNA) TL involvement in the regulation of miRNA biogenesis.
