DNA/RNA

 
  Schematic view of the gene with approximate sizes of introns (kb) and exons (bp); the coding region (violet) translates into a 500 amino acid product with three functional subunits.
Description 7313 bp, 5 exons, 4 introns
Transcription At least two splicing variants, including and excluding the second exon

Protein

Description 500 amino acids with at least three functional regions : 1. Two N-terminal nuclear localisation signals, 2. Seven canonical zinc-finger domains, 3. A serine rich C-terminus
Expression Heart, placenta, spleen, prostate, testis, ovary, small intestine, several tumours
Localisation Nuclear
Function One of the N-terminal nuclear localisation signals (NLS1) interacts with karyopherin a2, which escorts proteins into the nucleus. Three of the seven Zn-finger domains are responsible for interaction with DNA and PLAG1 specifically activates transcription from its consensus binding site. Potential PLAG1 binding sites have been found in the promoter of IGF2.
Homology Mouse and rat Plag1

Mutations

Somatic Involved in chromosome rearrangements in epithelial and mesenchymal tumours. These are typically complex structural abnormalities, resulting in an exchange of regulatory elements and abnormal expression of PLAG1.

Implicated in

Note
  
Entity Pleomorphic adenoma of the salivary gland
Disease Benign epithelial tumour
Prognosis Recovery after surgical removal
Cytogenetics The most common breakpoints are 3p21, 8q12, and 12q15
Hybrid/Mutated Gene The following translocations have been reported to result in hybrid genes involving PLAG1:
  • t(3;8)(p21;q12): CTNNB1 CTNNB1/PLAG1
  • t(5;8)(p13;q12): LIFR/PLAG1
  • Also, rearrangements between PLAG1 and TCEA1 have been detected in cases with normal karyotypes.
    • Abnormal Protein Fusions occur in the 5' regulatory regions, leading to promoter swapping and activation of PLAG1 expression while preserving coding sequences.
      
      
    Entity Carcinoma ex pleomorphic adenoma
    Disease Malignant epithelial tumour arising from pleomorphic adenoma
    Prognosis 30% five-year survival

    Hybrid/Mutated Gene Intragenic PLAG1 rearrangements demonstrated by fluorescence in situ hybridisation.
      
      
    Entity Lipoblastoma
    Disease Benign fat-forming tumour of childhood
    Prognosis Recovery after surgical removal
    Cytogenetics Structural abnormalities involving 8q11-13
    Hybrid/Mutated Gene The following rearrangements have been reported to result in hybrid genes involving PLAG1:
  • del(8)(q12q24), r(8): HAS2/PLAG1
  • t(7;8)(p22;q13): COL1A2/HAS2
    • Abnormal Protein Fusions occur in the 5' regulatory regions, leading promoter swapping and activation of PLAG1 expression while preserving coding sequences.
