Summary Information

Automatically generated summary

See sections below for more information

The gene mir-2a-1 stem loop is referred to in FlyBase by the symbol Dmel\mir-2a-1 (CR42899, FBgn0262377). It is a miRNA_gene from Drosophila melanogaster. Its molecular function is unknown. There is experimental evidence that it is involved in the biological process: negative regulation of cell death; negative regulation of translational initiation. 2 alleles are reported. No phenotypic data is available. It has one annotated transcript. Gene sequence location is 2L:19569897..19569972.

Additional comments

The annotation for mir-2a-1 has been changed in release 5.31 of the genome annotation, so that instead of representing a mature miRNA it now represents the precursor stem loop pre-miRNA. The symbol of the annotation has been changed from CR32965 to CR42899 to reflect this change.

(FlyBase Genome Annotators, 2010)

Other Comments

"mir-2" inhibits translation initiation without affecting mRNA stability.

(Thermann and Hentze, 2007)

mir-2a-1, mir-2a-2 and mir-2b-2 sequences are clustered within 400bp in 37E3-38A2.

(Sempere et al., 2003)

New annotation (CR32965) in release 3 of the genome annotation.
