GAP-43 Overexpression Lysate

HEK293T cells in 10-cm dishes were transiently transfected with a non-lipid polymer transfection reagent specially designed and manufactured for large volume DNA transfection. Transfected cells were cultured for 48hrs before collection. The cells were lysed in modified RIPA buffer (25mM Tris-HCl pH7.6, 150mM NaCl, 1% NP-40, 1mM EDTA, 1xProteinase inhibitor cocktail mix, 1mM PMSF and 1mM Na3VO4, and then centrifuged to clarify the lysate. Protein concentration was measured by BCA protein assay kit.

GAP43 (Growth associated protein 43) is a crucial component for regenerative response in the nervous system. GAP-43 is normally produced by neurons during developmental growth and axonal regeneration, but it is also expressed in specific regions of the normal adult nervous system. The protein is present at high levels in neuronal growth cones during development and axonal regeneration.

Heterozygous GAP3 knockout mice with GAP-43 levels reduced by one-half display significant memory impairments in cued conditioning, or on tests of nociceptive or auditory perception. Differentiating neurons that do not express GAP-43 show mislocalization of the centrosome and mitotic spindles, particularly in neurogenic cell divisions. Therefore, the neuronal precursor pool in the cerebellum fails to grow resulting in a cerebellum that is significantly smaller than normal. Total GAP-43 deletion is lethal within days of birth, demonstrating that GAP-43 is critical for the proper development of the mammalian CNS.
