  • Experimental Validation Results for HDAC8 Antibody (YA2994)
    Western blot analysis of extracts from K562(lane 2(20ug) and K562(lane 3(40ug) using HDAC8 Antibody (HY-P83249) Rabbit mAb. Proteins were transferred to a PVDF membrane and blocked with 5% non-fat milk in TBST for 2 hour at room temperature. The primary antibody (1/1000) and Loading control antibody (Beta Actin, HY-P80438, 1/10000) was used in 5% non-fat milk in TBST at 4°C overnight. Goat Anti-Mouse/Rabbit IgG-HRP Secondary Antibody (1/10000) was used for 1 hour at room temperature.

Background

  • Function

    HDAC8 (histone deacetylase 8) is a zinc-dependent class I histone deacetylase that regulates chromatin organization and transcription through deacetylation of both histone and nonhistone substrates, placing it at the center of epigenetic control mechanisms.[1] Mechanistically, HDAC8 participates in transcriptional regulation, cell-cycle progression, and genome maintenance, and recent evidence shows that HDAC8 activity contributes to replication-fork stability through regulation of the cohesin component SMC3 and suppression of replication-associated stress.[2] These functions connect HDAC8 to biological processes that govern proliferation, differentiation, and cellular homeostasis.[1][2] In disease settings, dysregulated HDAC8 has been implicated in multiple cancers, where it is associated with tumor cell proliferation, metastasis, immune evasion, and drug resistance, supporting its relevance as an epigenetic therapeutic target.[3][1] HDAC8 has also been linked to developmental and genetic disorders, including Cornelia de Lange syndrome and X-linked intellectual disability, indicating functions that extend beyond oncology.[1] Compared with related class I isoforms such as HDAC1, HDAC2, and HDAC3, HDAC8 displays distinct structural and substrate-recognition properties, recognizes both histone and nonhistone proteins, and therefore offers opportunities for isoform-selective pharmacological modulation.[1][4] For experimental applications, selective HDAC8 inhibitors have been developed to minimize the off-target effects associated with pan-HDAC inhibition, and these compounds are widely used to investigate HDAC8-dependent pathways and evaluate therapeutic strategies in cancer and other disease models.[1][4]

    Phosphorylated by PKA on serine 39. Phosphorylation reduces deacetylase activity observed preferentially on histones H3 and H4

  • Subunit

    Interacts with PEPB2-MYH11, a fusion protein consisting of the 165 N-terminal residues of CBF-beta (PEPB2) with the tail region of MYH11 produced by the inversion Inv(16)(p13q22), a translocation associated with acute myeloid leukemia of M4EO subtype (PubMed:12509458). The PEPB2-MYH1 fusion protein also interacts with RUNX1, a well known transcriptional regulator, suggesting that the interaction with HDAC8 may participate in the conversion of RUNX1 into a constitutive transcriptional repressor (PubMed:12509458). Interacts with CBFA2T3 (PubMed:11533236). Interacts with phosphorylated SMG5/EST1B; this interaction protects SMG5 from ubiquitin-mediated degradation (PubMed:16809764). Associates with alpha-SMA (smooth muscle alpha-actin) (PubMed:15772115)
