General annotation (Comments)

Function

S-adenosyl-L-methionine-dependent histone methyltransferase that specifically methylates 'Lys-9' of histone H3. May function as a DNA-binding transcription factor. Binds to the macrophage-specific TPA-responsive element (MTE) of the HMOX1 (heme oxygenase 1) gene and may act as a transcriptional activator of this gene. Ref.6

Catalytic activity

S-adenosyl-L-methionine + histone L-lysine = S-adenosyl-L-homocysteine + histone N(6)-methyl-L-lysine.

Subunit structure

Binds to the retinoblastoma protein (RB). Interacts with GATA3. Ref.4 Ref.10

Subcellular location

Nucleus. Ref.6 Ref.1 Ref.2

Tissue specificity

Highly expressed in retinoblastoma cell lines and in brain tumors. Also expressed in a number of other cell lines and in brain, heart, skeletal muscle, liver and spleen. Isoform 1 is expressed in testis at much higher level than isoform 3. Ref.2 Ref.5

Sequence similarities

Contains 8 C2H2-type zinc fingers.

Contains 1 SET domain.

Alternative products

This entry describes 3 isoforms produced by alternative splicing and alternative initiation. [Align] [Select]
Isoform 1 (identifier: Q13029-1)

Also known as: RIZ1;

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: Q13029-2)

Also known as: MTB-Zf;

The sequence of this isoform differs from the canonical sequence as follows:
     1679-1682: SYSL → RNFL
     1683-1718: Missing.
Note: No experimental confirmation available.
Isoform 3 (identifier: Q13029-3)

Also known as: RIZ2;

The sequence of this isoform differs from the canonical sequence as follows:
     1-201: Missing.
Note: Produced by alternative initiation at Met-202 of isoform 1.
