Amino acid replacement: P380S.
Contains a C to T change at 3L coordinate 3195636 (release 5.8), resulting in a proline to serine change at residue 380 in the Hsp83 protein.
Nucleotide substitution: C3195636T.

The cells in Hsp836-55 mutant clones experience a delay in cell cycle exit.
Hsp836-55 mutant clones in the proliferating regions of third instar larval eye or wing discs contain a similar number of mitotic cells as controls. Occasional mitotic cells are observed in the non-proliferating regions of the eye disc posterior to the morphogenetic furrow. Clone cells from the eye have a cell cycle that appears the same as in controls, although in wings more cells are in G2 than in controls.
Hsp836-55 is rescued by Hsp83+t7.5
Expression of Hsp83+t7.5 rescues the lethality and cell cycle exit defects seen in Hsp836-55 mutants.
