General description

Aspartoacylase (EC 3.5.1.15; UniProt Q8R3P0; also known as Acy-2, Aminoacylase-2, Nur-7) is encoded by the Aspa (also known as Acy2) gene (Gene ID 11484) in murine species. Aspartoacylase catalyzes the deacetylation of N-acetylaspartate (NAA) to generate free acetate in the central nervous system (CNS). Mutations in the ASPA gene cause the autosomal recessive neurodegenerative Canavan disease (CD) that results in inadequate lipid/myelin synthesis during development. Immunohistochemical staining reveals that aspartoacylase colocalizes with the oligodendrocyte marker CC1 throughout the brain, indicating its role in myelination.

Immunogen

N-terminally his-tagged full-length recombinant mouse Aspa/Nur7.

Application

Immunohistochemistry Analysis: A representative lot detected Aspa/Nur7-positive oligodendrocytes in corpus callosum/external capsule using free-floating mouse brain sections (Courtesy of Dr. John R. Moffett, Uniformed Services University of the Health Sciences).
Western Blotting Analysis: A representative lot detected Aspa/Nur7 in the cytosol, but not myelin, fraction from rat brain tissue homogenate (Madhavarao, C.N., et al. (2004). J Comp Neurol. 472(3):318-329).
Immunohistochemistry Analysis: A representative lot detected Aspa/Nur7 expression pattern in various regions of rat forebrain, including corpus callosum, cerebral cortex, hippocampal commissure (hc), fimbria, and anterior commissure (Madhavarao, C.N., et al. (2004). J Comp Neurol. 472(3):318-329).
Immunohistochemistry Analysis: A representative lot detected similar Aspa/Nur7 expression pattern as CC1 in various regions of rat forebrain, including the Purkinjie & axonal fiber layers of cerebellum, corpus callosum, as well as layer 2 of primary somatosensory cortex (Madhavarao, C.N., et al. (2004). J Comp Neurol. 472(3):318-329).

Experience-dependent myelination is hypothesized to shape neural circuit function and subsequent behavioral output. Using a contextual fear memory task in mice, we demonstrate that fear learning induces oligodendrocyte precursor cells to proliferate and differentiate into myelinating oligodendrocytes in the medial

Cuprizone is a copper-chelating agent that induces pathology similar to that within some multiple sclerosis (MS) lesions. The reliability and reproducibility of cuprizone for inducing demyelinating disease pathology depends on the animals ingesting consistent doses of cuprizone. Cuprizone-containing pelleted feed

COVID survivors frequently experience lingering neurological symptoms that resemble cancer-therapy-related cognitive impairment, a syndrome for which white matter microglial reactivity and consequent neural dysregulation is central. Here, we explored the neurobiological effects of respiratory SARS-CoV-2 infection and found white-matter-selective microglial
