HSP90 - an essential eukaryotic protein with implications for drug development

The heat-shock protein 90 (HSP90) family is a group of highly conserved molecular chaperones with important functions in protein folding and in signal transduction. The HSP90 protein structure is so well conserved that some HSP90 antibodies are reactive with a broad range of species from humans to chickens (1). In humans there are 17 known genes encoding the HSP90 family members. The HSP90 family consists of 4 different classes: HSP90AA, HSP90AB, HSP90B, and TRAP.

Integrin beta 1 binding protein 2

ITGB1BP2 is a muscle-specific protein cloned by a rat created by Branccio's group in Italy that was found to interact with the cytoplasmic domain of integrin beta 11. It is expressed only in heart and skeletal muscle but is not essential for normal development and differentiation of these tissues. Branccio's group published a follow-up study in Nature Medicine using an ITGB1BP2 antibody that the protein plays a critical role in sensing mechanical stress due to pressure overloading2.

HSP Antibodies: Novel Therapies for MMP-induced Metastatic Breast Cancer

The matrix metalloproteinases are zinc-dependent protease enzymes which interact with a range of ECM (extracellular matrix) proteins, and are activated by proteolytic cleavage. We at Novus Biologicals offer a wide range of top quality MMP reagents, including MMP3, MMP7, MMP9, MMP13 and MMP2 specific antibodies.

Heat Shock Proteins: An Overview

Heat Shock Proteins (HSPs) are a ubiquitous group of molecular chaperone proteins that have evolved unique mechanisms, within their host cells, to facilitate survival in hostile environments such as heat, oxidative (hypoxia), pH and cold.

The Heat is On: Heat Shock Proteins and the Link to Cancer

Novus Biologicals offers an extensive antibody catalog targeting heat shock proteins (HSPs). A large protein group covering a number of families, the HSPs are functionally related by their dramatic upregulation in response to stress. Stress triggers may include a rise in temperature or a similar environmental cause. Transcription is controlled by the heat shock factor, or HSF, protein family.
