Hsp70, heat-shock protein 70, hsp70B
AlphaFold produces a per-residue confidence score (pLDDT) between 0 and 100. Some regions with low pLDDT may be unstructured in isolation.
This duplication of the Hsp70Bb gene is present in certain strains including y; cn bw sp, which was sequenced in the Drosophila genome project, but not others. See FBrf0137034 and personal communication of Brian Bettencourt to FlyBase for details.

Please Note This section lists cDNAs and ESTs that fall within the genomic extent of the gene model, which may include cDNAs and ESTs of genes within introns, or of overlapping genes. Please see GBrowse for alignment of the cDNAs and ESTs to the gene model.
For each fully sequenced cDNA the DGRC maintains various forms of the cDNA (e.g tagged or untagged) in several different host vectors for subsequent cloning and expression in Drosophila and Drosophila cell lines.
Flies with no copies of the Hsp70 genes (Hsp70Aa, Hsp70Ab, Hsp70Ba, Hsp70Bb, Hsp70Bbb and Hsp70Bc) are unable to survive a severe heat shock. These flies show a lengthened heat-shock response and developmental delay following a non-lethal heat shock.
Some Drosophila strains, including that sequenced in the Drosophila genome project have three, not two, tandemly repeated Hsp70 genes at 87C1 (in addition to a reverse orientation Hsp70 gene, Hsp70Ba, approximately 40kb upstream). The distal-most gene of the three tandem copies is Hsp70Bc. The inner two tandem copies are Hsp70Bb and Hsp70Bbb.
The D.melanogaster strain used for sequencing the genome contains an additional, third tandem copy of an Hsp70 gene at 87C as well as the two tandemly repeated copies (Hsp70Bb and Hsp70Bc) which are found in many strains. This additional copy is named "Hsp70Bbb" (see FBrf0137034 and Bettencourt, 2002.1.16, personal communication to FlyBase).
