General description

Monoclonal Anti-LSD1 (AOF2) (mouse IgG1 isotype) is derived from the hybridoma LSD1-12 produced by the fusion of mouse myeloma cells (NS1) and splenocytes from BALB/c mice. Lysine specific demethylase 1 (LSD1) also known as amine oxidase flavin-containing domain 2 (AOF2) () is a lysine-specific demethylase. It is a nuclear protein containing a SWIRM (Swi3p, Rsc8p and Moira) domain, a flavin adenine dinucleotide (FAD)-binding motif and an amine oxidase domain. The LSD1 gene is mapped to human chromosome 1p36.12. LSD1 is referred to by additional names including KDM1A protein, BHC110(BRAF-HDAC complex protein 110) and nuclear polyamine oxidase (NPAO)().

Specificity

Monoclonal Anti-LSD1 (AOF2) recognizes human and mouse LSD1.

Immunogen

synthetic peptide corresponding to amino acids 832-847 of human LSD1/BHC110. This sequence is identical in bovine, rat, mouse, and frog.

Application

Monoclonal Anti-LSD1 (AOF2) antibody produced in mouse has been used:
  • immunofluorescence
  • immunoblotting
  • immunoprecipitation
  • immunocytochemistry

Biochem/physiol Actions

Lysine Specific Demethylase 1 (LSD1) is a component of several histone deacetylase complexes that function through modifying chromatin structure to repress transcription.LSD1 action can signal either activation or repression of transcription. Demethylation of histone H3 Lys4 by LSD1 leads to transcriptional repression of target genes, while demethylation of histone H3 at Lys9 leads to depression of androgen receptor target genes. The activity of LSD1 (AOF2) is regulated by its associated factors namely, corepressor to the REST (RE1 silencing transcription factor/neural restrictive silencing factor)(CoREST). This, in turn, promotes demethylation by enhancing the association of LSD1 with the nucleosomes and also protects LSD1 from proteasomal degradation. LSD1 is a component of nucleosome remodeling and deacetylase (NuRD). It regulates neuronal development and favors neural stem cell proliferation. It highly expressed in acute myeloid leukemia and many solid tumors.

Physical form

Solution in 0.01 M phos­phate buffered saline, pH 7.4, containing 15 mM sodium azide.

Storage and Stability

For continuous use, store at 2-8 °C for up to one month. For extended storage, freeze in working aliquots. Repeated freezing and thawing, or storage in “frost-free” freezers, is not recommended. If slight turbidity occurs upon prolonged storage, clarify the solution by centrifugation before use. Working dilutions should be discarded if not used within 12 hours.

Posttranslational modifications of histone N-terminal tails impact chromatin structure and gene transcription. While the extent of histone acetylation is determined by both acetyltransferases and deacetylases, it has been unclear whether histone methylation is also regulated by enzymes with opposing activities.
