Accession number: NM_000817.The HsGAD1 primers and probe can be used to quantify a control locus in chromatin immunoprecipitation (ChIP) assays with chromatin prepared from human cells. GAD1 (Glutamic acid decarboxylase) is expressed in neurons but silenced in most other cell types. The primers and probe are located in exon 1, within 1 kb of the transcription start site. In most cell types GAD1 is enriched with histone modifications associated with silencing (e.g. Histone H3 K9 mono methylation, see image with ab9045). Whereas it shows low levels of histone modifications associated with active gene transcription such as Histone H3 K9 acetylation (see image with ab4441).
Isoform 3 is expressed in pancreatic islets, testis, adrenal cortex, and perhaps other endocrine tissues, but not in brain.
Defects in GAD1 are the cause of cerebral palsy spastic quadriplegic type 1 (CPSQ1) [MIM:603513]. A non-progressive disorder of movement and/or posture resulting from defects in the developing central nervous system. Affected individuals manifest symmetrical, non-progressive spasticity and no adverse perinatal history or obvious underlying alternative diagnosis. Developmental delay, mental retardation and sometimes epilepsy can be part of the clinical picture.
The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
