The Drosophila melanogaster similar bHLH-PAS gene encodes a protein related to human hypoxia-inducible factor 1 alpha and Drosophila single-minded

Gene. 1996 Jun 26;172(2):249-54. doi: 10.1016/0378-1119(96)00060-1.

Abstract

The Drosophila melanogaster (Dm) similar (sima) gene was isolated using a low-stringency hybridization screen employing a Dm single-minded gene basic helix-loop-helix (bHLH) DNA probe. sima is a member of the bHLH-PAS gene family and the conceptual protein shares a number of structural features, including a bHLH domain, PAS domain, and homopolymeric amino acid stretches. Sima is most closely related to the human hypoxia-inducible factor 1 alpha bHLH-PAS protein. In situ hybridization experiments reveal that sima is transcribed in most or all cells throughout embryogenesis. It has been cytologically mapped to position 99D on the third chromosome, and is not closely linked to other known bHLH-PAS genes.
