Western blot - Anti-Hsp 90 alpha antibody [EPR27270-11] (AB303516)
Blocking / Diluting buffer and concentration : 5% NFDM/TBST The samples were run on a Bis-Tris gel. Performed under reducing conditions. False colour image of Western blot : Anti-Hsp90 alpha antibody (ab303516) staining at 1/1000 dilution, shown in green; Mouse anti-GAPDH antibody [6C5] (ab8245) loading control staining at 1/20000 dilution, shown in red. In Western blot, ab303516 was shown to bind specifically to Hsp90 alpha. A band was observed at 90 kDa in wild-type 293T cell lysates with no signal observed at this size in Hsp90 alpha knockout cell line. To generate this image, wild-type and Hsp90 alpha knockout 293T cell lysates were analyzed. First, samples were run on an SDS-PAGE gel then transferred onto an immobilon-FL PVDF membrane. Membranes were blocked in in Intercept® (TBS) Blocking Buffer diluted with an equal volume of 0.1% TBS before incubation with primary antibodies overnight at 4 °C. Blots were washed four times in TBS-T, incubated with secondary antibodies for 1 h at room temperature, washed again four times then imaged.

Biological function summary
Hsp90 alpha assists in maintaining protein homeostasis and is part of a larger chaperome complex including co-chaperones and other chaperones such as Hsp70. It plays an important role in stress response by stabilizing proteins and preventing aggregation. Hsp90 alpha is essential for the normal function of several kinases and transcription factors which are important for cell signaling and regulation processes. It functions as a mediator for cellular response to environmental cues.
Pathways
Hsp90 alpha is an integral component in the signal transduction and cell cycle control pathways. It interacts with various signaling proteins and receptors like AKT and steroid hormone receptors to facilitate their proper folding and activation. Furthermore Hsp90 alpha influences the MAPK/ERK pathway playing a role in cell proliferation and differentiation. Its interaction with Hsp90 protein clients creates a regulatory framework across multiple pathways allowing precise control over cellular function.
