Heat shock protein 27 (HSP27) also called HSPB1 is a member of small heat shock protein (sHsps). HSB1 helps in developing a stable state during stress conditions like heat shock or oxidative injuries. Several studies have performed for the identification of HSPB1 function. However, limitation to highlight structural and phylogenetic relationships of HSPB1 in various organisms. Therefore, the aim of this study to investigate HSPB1 protein in twelve different organisms namely Homo Sapiens (Human), Dugesia japonica (Flatworms), Sus scrofa (Pig), Carassius auratus (Goldfish), Oreochromis niloticus (Nile Tilapia), Rattus norvegicus (Norway Rat), Xenopus laevis (African clawed Frog), Canis lupus familiaris (Dog), Musca domestica (House Fly), Phen...
