Descriptions
SmyD2 belongs to a new class of chromatin regulators that control gene expression in heart development and tumorigenesis. Besides methylation of histone H3 K4, SmyD2 can methylate non-histone targets including p53. The methyltransferase activity of SmyD proteins has been proposed to be regulated by autoinhibition via the intra- and interdomain bending of the conserved C-terminal domain (CTD). The CTD stabilizes the autoinhibited conformation of SmyD2 and restricts access to the catalytic site.<br> In addition, the CTD is structurally similar to tetratricopeptide repeats (TPR), a motif through which many cochaperones bind to the heat shock protein Hsp90. The CTD may be important for the activation of SmyD proteins by Hsp90.

3 GO annotations of cellular component
| Name | Definition |
|---|---|
| cytoplasm | The contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures. |
| cytosol | The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes. |
| nucleus | A membrane-bounded organelle of eukaryotic cells in which chromosomes are housed and replicated. In most cells, the nucleus contains all of the cell's chromosomes except the organellar chromosomes, and is the site of RNA synthesis and processing. In some species, or in specialized cell types, RNA metabolism or DNA replication may be absent. |

7 GO annotations of biological process
| Name | Definition |
|---|---|
| chromatin remodeling | A dynamic process of chromatin reorganization resulting in changes to chromatin structure. These changes allow DNA metabolic processes such as transcriptional regulation, DNA recombination, DNA repair, and DNA replication. |
| heart development | The process whose specific outcome is the progression of the heart over time, from its formation to the mature structure. The heart is a hollow, muscular organ, which, by contracting rhythmically, keeps up the circulation of the blood. |
| negative regulation of cell population proliferation | Any process that stops, prevents or reduces the rate or extent of cell proliferation. |
| negative regulation of transcription by RNA polymerase II | Any process that stops, prevents, or reduces the frequency, rate or extent of transcription mediated by RNA polymerase II. |
| peptidyl-lysine dimethylation | The methylation of peptidyl-lysine to form peptidyl-N6,N6-dimethyl-L-lysine. |
| peptidyl-lysine monomethylation | The methylation of peptidyl-lysine to form peptidyl-N6-methyl-L-lysine. |
| regulation of DNA damage response, signal transduction by p53 class mediator | Any process that modulates the frequency, rate or extent of the cascade of processes induced by the cell cycle regulator phosphoprotein p53, or an equivalent protein, in response to the detection of DNA damage. |
