Gene Summary
Histone deacetylase 4 (HDAC4) encodes a Class IIa histone deacetylase that modulates gene expression by associating with transcriptional factors. It is regulated by nucleocytoplasmic shuttling and contributes to embryogenesis, muscle development, circadian function, energy balance and memory.

Gene Group (FlyBase)
RPD3/HDA1 LYSINE DEACETYLASES -
The RPD3/HDA1 family are Zn2+-dependent lysine deacetylases that share a common catalytic core domain. (Adapted from FBrf0159755).
SUMO TRANSFERASES -
SUMO transferases catalyze the transfer of SUMO from either E2 or E3 enzyme to a substrate.
Pathway (FlyBase)
Insulin-like Receptor Signaling Pathway Core Components -
The Insulin-like Receptor (IR) signaling pathway in Drosophila is initiated by the binding of an insulin-like peptides to the Insulin-like receptor (InR). (Adapted from FBrf0232297, FBrf0230017 and FBrf0229989.)

Model Confidence:
  • Very high (pLDDT > 90)
  • Confident (90 > pLDDT > 70)
  • Low (70 > pLDDT > 50)
  • Very low (pLDDT < 50)

AlphaFold produces a per-residue confidence score (pLDDT) between 0 and 100. Some regions with low pLDDT may be unstructured in isolation.

Testis-specificity index

The testis specificity index was calculated from modENCODE tissue expression data by Vedelek et al., 2018 to indicate the degree of testis enrichment compared to other tissues. Scores range from -2.52 (underrepresented) to 5.2 (very high testis bias).

Additional Descriptive Data

In early embryos (< 1 hour AEL) HDAC4 is expressed ubiquitously, and concentrated around the nuclei. At about 2 hours of development expression is decreased, and is refined to a broad anterior domain. Seven stripes appear at cellularization, between 70% and 24% egg length, the broad anterior stripe is lessened in intensity. During gastrulation, anoter seven stripes appear between the first seven, and these are maintainted through embryonic stage 11. The 3 kB transcript is predominant in larvae, while the 5.5 kB transcript is predominant in embryos and adults.

A single confocal plane through the Kenyon cells

at the level of the calyx (asterisk) shows HDAC4 is predominantly localized to the calyx and cytoplasm. In a subset of cells, nuclear HDAC4 expression is observed, which always co-localizes with Mef2.

        HDAC4 is a repressor of long-term memory and modulates normal memory formation.

        S2 cells which have been treated with dsRNA made from templates generated with primers directed against HDAC4 show no significant inhibition of cell growth.
