PA1-012 detects phospho-alpha-B crystallin (Ser59) from bovine, human and rat samples. This antibody does not detect the unphosphorylated form of the protein.
PA1-012 has been successfully used in Western blot, immunohistochemistry and immunofluorescence procedures. By Western blot, this antibody detects an ~20 kDa protein representing recombinant bovine phospho-alpha-B crystallin (Ser59). Immunofluorescence staining of phospho-alpha-B crystallin (Ser59) in human brain from Alexander"e;s diseased patients results in staining of cells in the cerebral cortex.
The PA1-012 immunogen is a synthetic phosphopeptide corresponding to residues F(54) L R A P S(p) W I D T G(64) of human alpha-B Crystallin.
Lens proteins consist almost entirely of crystallins (about 95%). Crystallins are also found vertebrate skeletal muscle tissue. In the lens, their structural function is to assist in maintaining the proper refractive index of the lens. The mammalian lens contains 3 major classes of crystallins: alpha, beta, and gamma. Alpha-crystallin is the largest of the crystallins and is composed of 2 primary gene products--alpha-A and alpha-B. There are at least 5 different proteins comprising the beta-crystallins. The gamma-crystallins are monomeric, but there are at least 5 gamma crystallins identified in bovine and rat lens.
Alpha-Crystallin comprises 40% of total lens protein composition. In addition to maintaining proper refractive index, it also functions in a chaperone like manner by preventing the formation of aggregates possibly leading to cataract formation. It is believed that the phosphorylated states of the alpha-crystallin occur in response to cellular stress and may serve a structural control function and play a role in protein maintenance. Alpha-B crystallin has been linked to Alexander"e;s disease where it accumulates in brain cells of those afflicted.
