General annotation (Comments)

Function

Responsible for the deacetylation of lysine residues on the N-terminal part of the core histones (H2A, H2B, H3 and H4). Histone deacetylation gives a tag for epigenetic repression and plays an important role in transcriptional regulation, cell cycle progression and developmental events. Represses MEF2-dependent transcription. Ref.1 Ref.3 Ref.8 Ref.9 Ref.13

Isoform 3, called MITR/HDRP, lacks active site residues and therefore is catalytically inactive. Represses MEF2-dependent transcription by recruiting HDAC1 and/or HDAC3. Seems to inhibit skeletal myogenesis and to be involved in heart development. Protects neurons from apoptosis, both by inhibiting c-Jun phosphorylation by MAPK10 and by repressing c-Jun transcription via HDAC1 recruitment to c-Jun promoter. Ref.1 Ref.3 Ref.8 Ref.9 Ref.13

Catalytic activity

Hydrolysis of an N(6)-acetyl-lysine residue of a histone to yield a deacetylated histone.

Enzyme regulation

Inhibited by Trichostatin A (TSA) and suberoylanilide hydroxamic acid. Ref.1

Subunit structure

Homodimer. Interacts with CTBP1. The phosphorylated form interacts with 14-3-3 By similarity. Interacts with HDAC1 and HDAC3, and probably with HDAC4 and HDAC5. Interacts with MEF2, MAPK10, ETV6, NCOR1 and BCL6.

Subcellular location

Nucleus By similarity.

Tissue specificity

Broadly expressed, with highest levels in brain, heart, muscle and testis. Isoform 3 is present in human bladder carcinoma cells (at protein level). Ref.1 Ref.3 Ref.9 Ref.2

Post-translational modification

Phosphorylated on Ser-220 and Ser-450; which promotes 14-3-3-binding, impairs interaction with MEF2, and antagonizes antimyogenic activity. Phosphorylated on Ser-240; which impairs nuclear accumulation By similarity. Isoform 7 is phosphorylated on Tyr-1010.

Sumoylated. Ref.3 Ref.11

Involvement in disease

A chromosomal aberration involving HDAC9 is found in a family with Peters anomaly [MIM:604229]. Translocation t(1;7)(q41;p21) with TGFB2 resulting in lack of HDAC9 protein. Peters anomaly consists of a central corneal leukoma, absence of the posterior corneal stroma and Descemet membrane, and a variable degree of iris and lenticular attachments to the central aspect of the posterior cornea.

Sequence similarities

Belongs to the histone deacetylase family. Type 2 subfamily.

Alternative products

This entry describes 7 isoforms produced by alternative splicing. [Align] [Select]

Note: Additional isoforms seem to exist.
Isoform 1 (identifier: Q9UKV0-1)

This isoform has been chosen as the 'canonical' sequence. All positional information in this entry refers to it. This is also the sequence that appears in the downloadable versions of the entry.
Isoform 2 (identifier: Q9UKV0-2)

The sequence of this isoform differs from the canonical sequence as follows:
     487-574: Missing.
Isoform 3 (identifier: Q9UKV0-3)

Also known as: HDRP; MITR;

The sequence of this isoform differs from the canonical sequence as follows:
     575-590: PFLEPTHTRALSVRQA → VIGKDLAPGFVIKVII
     591-1011: Missing.
Note: Major form in most tissues. Inactive due to lack of active site residues.
Isoform 4 (identifier: Q9UKV0-4)

Also known as: HDAC9a;

The sequence of this isoform differs from the canonical sequence as follows:
     861-879: GTGLGEGYNINIAWTGGLD → RFISLEPHFYLYLSGNCIA
     880-1011: Missing.
Isoform 5 (identifier: Q9UKV0-5)

     1006-1011: MSLKFS → KYWKSVRMVAVPRGCALAGAQLQEETETVSALASLTVDVEQPFAQEDSRTAGEPMEEEPAL
Note: Phosphorylated on Tyr-1007 (Probable).
Isoform 6 (identifier: Q9UKV0-6)

The sequence of this isoform differs from the canonical sequence as follows:
     88-88: K → KLQQ
     218-261: Missing.
     1006-1011: MSLKFS → KYWKSVRMVAVPRGCALAGAQLQEETETVSALASLTVDVEQPFAQEDSRTAGEPMEEEPAL
Note: Ref.6 (AAI11736) sequence differs from that shown due to a frameshift in position 1021. Phosphorylated on Tyr-966 (Probable). Excluded from the nucleus. Does not interact with ETV6..
Isoform 7 (identifier: Q9UKV0-7)

The sequence of this isoform differs from the canonical sequence as follows:
     88-88: K → KLQQ
     1006-1011: MSLKFS → KYWKSVRMVAVPRGCALAGAQLQEETETVSALASLTVDVEQPFAQEDSRTAGEPMEEEPAL
