(2002). Previous studies identified LSD1 in the Co-REST complex whose primary function is to silence neuronal specific genes in non-neuronal cells (Regulation of neuronal traits by a novel transcriptional complex.Corepressor-dependent silencing of chromosomal regions encoding neuronal genes.A DNA vector-based RNAi technology to suppress gene expression in mammalian cells.Cloning of p57KIP2, a cyclin-dependent kinase inhibitor with unique domain structure and tissue distribution.p57(Kip2) cooperates with Nurr1 in developing dopamine cells. The SWIRM (oval with vertical stripes), amine oxidase domain (filled oval), and FAD binding motif (diamond) are drawn proportionally. The SWIRM domain: a conserved module found in chromosomal proteins points to novel chromatin-modifying activities. is a fellowship award recipient from the NIH (GM70095-02). For the four examples given above (see Histone deacetylase inhibitors may modulate the latency of some viruses, resulting in reactivation.Recently, histone deacetylase inhibitors showed activity against certain Class of enzymes important in regulating DNA transcription At least two models are currently being considered to explain the turnover of methyl groups on histones. The FDH assay was coupled with the demethylation reaction using 15 μg of LSD1 and the substrate diMeK4H3 peptides at an initial concentration of 50 μM. Here, we provide evidence that LSD1 (KIAA0601), a nuclear homolog of amine …
Estimated HIS-LSD1 concentration is 3 μg/μl. (E) Formaldehyde production was monitored by measuring NADH production at OD 340 nm in reactions containing 10 μg of HIS-LSD1 together with 10 μM of diMeK4H3, diMeR2H3, or diMeK9H3 peptides as substrates, respectively.

The function, activity, and stability of proteins can be controlled by These are just some examples of constantly emerging non-histone, non-chromatin roles for HDACs. (C) LSD1 dose-dependent formaldehyde production.
Equal amounts of histones were used within each set of reactions (Control, LSD1-, or LSD1ΔC-treated) as shown by Ponceau S staining of the blots (panels A5, C5, and D4) or by blotting with a histone H3-specific antibody (panel B5). For more detailed analysis of modification-specific antibodies that were used in this study, please refer to Upstate Inc. and AbCam at (A) The range of formaldehyde used was from 1 pmole to 10 nmole in a 100-μl reaction, which serves as the standard curve for the experiments shown in (B) The range of formaldehyde used was 1 to 500 pmole, and this standard curve was used for the experiments shown in Aravind, L., and Iyer, L.M. is a fellowship award recipient from the NIH (F32GM070690). LSD1 specifically demethylates histone H3 lysine 4, which is linked to active transcription. As shown in A spectrophotometric method for determining the oxidative deamination of methylamine by the amine oxidases.
The amount of HIS-LSD1 used in the assays was visualized by Western blotting using an anti-HIS epitope tag antibody (lower panel).
