17. data collectively suggest that silencing of PRMT1 exerts anti-catabolic and anti-inflammatory effects on IL-1beta-induced chondrocytes via suppressing the Gli-1 mediated Hedgehog signaling pathway, indicating that PRMT1 plays a critical role in OA development and serves as a promising therapeutic target for OA.

18. Deacetylation on both K200 and K205 by Sirtuin 1 (Sirt1) and acetylation of p300 (EP300) on K205 collaboratively prepare the motif for SCF(Fbxl17) binding thereby triggering PRMT1 protein degradation.

19. PRMT1 has a role in regulating MYCN in neuroblastoma

20. Analysis of deletion constructs of SERBP1 showed that the C-terminal third of the SERBP1 protein, which contains one of its two substrate sites for protein arginine N-methyltransferase 1 (PRMT1), is necessary and sufficient for it to interact with RACK1

Zebrafish Protein Arginine Methyltransferase 1 (PRMT1) interaction partners

1. prmt8 may play important roles non-overlapping with prmt1 in embryonic and neural development depending on its specific N-terminus.

2. prmt1 gene is actively and ubiquitously expressed at both RNA and protein levels at the early developmental stages of zebrafish.

Xenopus laevis Protein Arginine Methyltransferase 1 (PRMT1) interaction partners

1. PRMT1 functions transiently as a coactivator in thyroid hormone (T3) receptor (TR)-mediated transcription by enhancing TR-T3 response element binding and further suggest that PRMT1 has tissue-specific roles in regulating the rate of metamorphosis.

Pig (Porcine) Protein Arginine Methyltransferase 1 (PRMT1) interaction partners

1. Results suggest that part of the type I arginine methyltransferases in brains, mainly PRMT1, are sequestered in an inactive form as they associated with membranes or large subcellular complexes.

Mouse (Murine) Protein Arginine Methyltransferase 1 (PRMT1) interaction partners

1. PRMT1 became activated upon IGF-1 stimulation.

2. we disrupted PRMT1 function in neural crest cell (NCC)-derived tissues using Wnt1-Cre. NCC-specific deletion of Prmt1 caused cleft palate and craniofacial malformations, including reductions in the size of the head, mandible, and tongue. In the Prmt1-deficient mice, palate mesenchymal cell proliferation was dramatically reduced, and palatal shelves failed to reach the midline, resulting in a complete cleft palate phenotyp

3. PRMT1 thus regulates Th17 differentiation by controlling the reciprocal recruitment of STAT3 and STAT5.

4. PRMT1 regulates the transcription activity of NF-kappaB by directly interacting with it in RANKL-treated bone marrow-derived macrophages.

5. Developmental changes in the placental expression of PRMT1 and in protein arginine methylation status during pregnancy.

6. We further determined that Prmt1 depletion resulted in significant downregulation of Msx1 in calvaria-derived preosteoblast and primordium of frontal bone and mandible. Our study reveals critical roles of PRMT1 in the formation of CNC-derived craniofacial bones and suggests that Prmt1 is an upstream regulator of Msx1 in craniofacial bone development

7. Cardiac specific PRMT1 ablation causes heart failure through CaMKII dysregulation

8. PRMT activity is selectively augmented during the initial activation of exercise-induced skeletal muscle remodeling in vivo.

9. PRMT1 inhibition, such as induced by alcohol, may result in epigenetic changes leading to loss of Hnf4alpha. This effect may contribute to alcohol's ability to promote liver tumors

10. the present study increases our understanding of PRMT1, -4, and -5 biology during the plasticity of skeletal muscle development. Our results provide evidence for a role of PRMT1, via a mitochondrially mediated mechanism, in driving the muscle differentiation program.

17. Data, including data from studies in cells from knockout mice, suggest that Prmt1 activity was necessary for c-Myc binding to acetyltransferase p300 in myeloid cells; Prmt1 inhibition decreases p300 recruitment to c-Myc target promoters and increased Hdac1 recruitment.
