It can help other proteins for their assembling, folding and translocating, and plays a role in protecting cells against injuries and other types of stress. In addition, HSP60 is frequently recognized by the immune system as predominant antigens during infections and the progression of certain autoimmune diseases and might provide a novel strategy for the development of immunotherapeutics. This review focuses on distribution, molecular chaperone mechanism, function and gene expression regulation of HSP60. [展开更多

It is recruited to peripheral sites through myristoylation and the SH3 domain. Src initiates intracellular signal trandsduction pathways that influence cell adhesion, migration, growth, differentiation and survival though catalytic domain. Src is normally maintained in an inactive conformation because of carboxy terminal Src kinase, but can be activated transiently during cellular events such as mitosis or constitutively by abnormal events such as mutation and some cancers. In additions, c-Src protein is found to be highly activated and the Src gene is frequently over-expressed in many cancers. These findings suggest that the relationship between c-Src activation/over-expression and cancer progression appears to be significant.展开更多
