Abstract
Very little is known about SET- and MYND-containing protein 2 (SMYD2), a member of the SMYD protein family. However, the interest in better understanding the roles of SMYD2 has grown because of recent reports indicating that SMYD2 methylates p53 and histone H3. In this study, we present a combined proteomics and genomics study of SMYD2 designed to elucidate its molecular roles. We report the cytosolic and nuclear interactome of SMYD2 using a combination of immunoprecipitation coupled with high throughput MS, chromatin immunoprecipitation coupled with high throughput MS, and co-immunoprecipitation methods. In particular, we report that SMYD2 interacted with HSP90alpha independently of the SET and MYND domains, with EBP41L3 through the MYND domain, and with p53 through the SET domain. We demonstrated that the interaction of SMYD2 with HSP90alpha enhances SMYD2 histone methyltransferase activity and specificity for histone H3 at lysine 4 (H3K4) in vitro. Interestingly histone H3K36 methyltransferase activity was independent of its interaction with HSP90alpha similar to LSD1 dependence on the androgen receptor. We also showed that the SET domain is required for the methylation at H3K4. We demonstrated using a modified chromatin immunoprecipitation protocol that the SMYD2 gain of function leads to an increase in H3K4 methylation in vivo, whereas no observable levels of H3K36 were detected. We also report that the SMYD2 gain of function was correlated with the up-regulation of 37 and down-regulation of four genes, the majority of which are involved in the cell cycle, chromatin remodeling, and transcriptional regulation. TACC2 is one of the genes up-regulated as a result of SMYD2 gain of function. Up-regulation of TACC2 by SMYD2 occurred as a result of SMYD2 binding to the TACC2 promoter where it methylates H3K4. Furthermore the combination of the SMYD2 interactome with the gene expression data suggests that some of the genes regulated by SMYD2 are closely associated with SMYD2-interacting proteins.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
