dme-mir-2b-2 precursor miRNA
Summary
Caution, this is an AI generated summary based on literature. This may have errors. ?
Dme-mir-2b is a member of the miR-2 family in Drosophila, with its mature sequence being one nucleotide longer than previously annotated in miRBase [PMC3268580]. The specific roles of dme-mir-2b in Drosophila development and physiology are not yet fully understood [PMC9100521]. However, overexpression of dme-mir-2b using the Act-Gal4 driver leads to almost complete lethality, indicating its significant role during embryogenesis and development [PMC9100521]. Additionally, overexpression experiments using Pdf-Gal4 suggest that dme-mir-2b is crucial for the photoperiodic response, with alterations in expression levels affecting diapause [PMC9100521]. Dme-mir-2b is one of seven miRNAs found to be differentially expressed between long and short photoperiods, with higher expression levels during longer days [PMC9100521].

Comments
Stark et al. [2] have identified targets for miR-2 in Drosophila using computational prediction followed by experimental validation. miR-2 regulates the proapoptotic genes reaper, grim and sickle, suggesting that it may be involved in the control of apoptosis.
