Western blot analysis of extracts from MCF-7(lane 2(20μg) , Hela(lane 3(20μg) ,K562(lane 4(20μg)and THP-1( lane 5(20μg) using Phospho-Hsp27 (Ser82) Antibody (HY-P80465). Proteins were transferred to a PVDF membrane and blocked with 5% non-fat milk in TBST for 2 hour at room temperature. The primary antibody (1/1000) and Loading control antibody (Beta Actin, HY-P80993，1/10000) was used in 5% non-fat milk in TBST at 4°C overnight. Goat Anti-Rabbit IgG-HRP Secondary Antibody (HY-P8001，1/10,000) was used for 1 hour at room temperature.
Background
-
Function
Hsp27 is a Small heat shock protein which functions as a molecular chaperone probably maintaining denatured proteins in a folding-competent state. Plays a role in stress resistance and actin organization. Through its molecular chaperone activity may regulate numerous biological processes including the phosphorylation and the axonal transport of neurofilament proteins[1][2][3][4].

Expression
Tissue_specificity:The substance was detected in all tissues tested: skeletal muscle, heart, aorta, large intestine, small intestine, stomach, esophagus, bladder, adrenal glands, thyroid gland, pancreas, testes, adipose tissue, kidneys, liver, spleen, cerebral cortex, serum, and cerebrospinal fluid. The highest concentrations were found in the heart and tissues composed of striated and smooth muscle.
Induction:Up-regulated in response to environmental stresses such as heat shock (PubMed:8325890) . Up-regulated by estrogen stimulation (PubMed:2743305) ; (Microbial infection) Up-regulated in response to enterovirus 71 (EV71) infection (at protein level) -
Subunit
