    text
  • predominantly in nucleus
  • basic FUNCTION
  • methylating (mono and asymmetric dimethylation) the guanidino nitrogens of arginyl residues present in a glycine and arginine-rich domain
  • acting as a restriction factor for HIV replication
  • specifically methylates the nonhistone chromatin protein HMGA1
  • plays a role as a regulator of DNA base excision repair
  • regulate DNA repair and gene expression
  • mammalian methyltransferase for H3 R2 and a crucial negative regulator of H3 K4 trimethylation and transcriptional activation
  • functioning as a transcriptional coactivator that can also regulate alternative splicing
  • has a dual role in regulating gene expression and that these two functions can occur independently of each other
  • dysregulation of PRMT1 and PRMT6 can be involved in human carcinogenesis
  • utilizes a rapid equilibrium random mechanism with dead-end EAP and EBQ complexes
  • is potentially important for ES cell pluripotency and self-renewal
  • facilitates cell proliferation and blocks senescence by regulation of tumor suppressor genes and that this might contribute to the oncogenic capacity of PRMT6
  • methylate the HMGA1 protein in the second AT hook and likely regulates chromatin structure organization
  • regulates cell cycle progression
  • implicated in transcriptional regulation, DNA repair, and human immunodeficiency virus pathogenesis
  • its overexpression is associated with regulation of motility and invasion through up-regulation of THBS1 and down-regulation of MMPs in cancer cells
  • arginine methyltransferase known to methylate AT-hook motifs, downregulating the expression of HLA-DQ, but not HLA-DR, in an AT-hook-dependent manner
  • PRMT6 is involved in the regulation of hepatic glucose metabolism in a CRTC2-dependent manner

    protein
  • directly regulates the THBS1 promoter activity (THBS1 is a transcriptional repression target of PRMT6)
  • regulates gene transcription via its ability to methylate histones H3 and H4
  • CDKN1A is a direct target of PRMT6 and the corresponding histone mark H3R2me2
  • HMGA1 is a substrate for PRMT6, having a modulatory role on the methyltransferase activity of PRMT6
  • negative function of PRMT6 on invasion and migration of cancer cells through up-regulation of THBS1 and down-regulation of MMP2 and MMP9
  • PELP1 interacts with the arginine methyltransferase PRMT6 and modifies PRMT6 functions
  • in cells, PRMT6 mediated asymmetric dimethylation of multiple arginine residues of CRTC2, which enhanced the association of CRTC2 with CREB on the promoters of gluconeogenic enzyme-encoding genes
