Conjugate Avi-tag Biotinylated
E. coli biotin ligase (BirA) is highly specific in covalently attaching biotin to the 15 amino acid AviTag peptide. This recombinant protein was biotinylated in vivo by AviTag-BirA technology, which method is BriA catalyzes amide linkage between the biotin and the specific lysine of the AviTag.

Target Background

The insulin-like growth factors possess growth-promoting activity. Major fetal growth hormone in mammals. Plays a key role in regulating fetoplacental development. IGF2 is influenced by placental lactogen. Also involved in tissue differentiation. In adults, involved in glucose metabolism in adipose tissue, skeletal muscle and liver. Acts as a ligand for integrin which is required for IGF2 signaling. Positively regulates myogenic transcription factor MYOD1 function by facilitating the recruitment of transcriptional coactivators, thereby controlling muscle terminal differentiation. Inhibits myoblast differentiation and modulates metabolism via increasing the mitochondrial respiration rate.; Preptin undergoes glucose-mediated co-secretion with insulin, and acts as physiological amplifier of glucose-mediated insulin secretion. Exhibits osteogenic properties by increasing osteoblast mitogenic activity through phosphoactivation of MAPK1 and MAPK3.

  1. These results indicated that editing IGF2 intron 3-3072 site using CRISPR-Cas9 technology improved meat production in Bama pigs. PMID: 30259067
  2. trans-associations occur between three imprinted genes IGF2, DLK1 and MEG3 both in fetal liver and muscle cells. PMID: 27716032
  3. A single nucleotide polymorphism in a regulatory region of intron 3 within the porcine IGF2 gene is associated with increased lean deposition and decreased fat deposition in pigs with paternal A alleles compared with pigs with paternal G alleles. PMID: 25367517
  4. These findings indicated that the mRNA of H19 and IGF2 genes is susceptible to in vitro environments during the process of ES cell derivation from blastocysts but DNA methylation status at this region was well maintained. PMID: 24794444
  5. study did not find any significant associations for polymorphisms in insulin-like grwoth factor 2, GTP Binding Protein alpha Subunits, Gs and melanocortin receptor 4 genes with reproductive traits of Polish Landrace and Large White pigs PMID: 23199214
  6. The results suggested that IFG-1 and -2 and their receptors are differentially expressed at the maternal and fetal components of the attachment site. PMID: 21685713
  7. Genetic variation in the promoter region of the IGF2 gene is associated with intramuscular fat content in porcine skeletal muscle. PMID: 21779802
  8. The IGF2 G allele has strong adipogenic effects at the subcutaneous adipose tissue level and enhances the intermuscular fat content in ham. PMID: 21907500
  9. IGF-I, IGF-II, and IGFBP-3 mRNA were positively correlated with IGF-IR from 50E to 180D, suggesting that the expression of IGF-system genes exhibits specific developmental patterns in the skeletal muscle tissues. PMID: 21570979
  10. The imprinting status in adult liver, muscle and kidney tissues were also not reflected in the methylation patterns of IGF2 DMRs 1 and 2. PMID: 21575277
  11. The expression of IGF-I and IGF-II in native growth plates of prepubertal piglets and under different cell culture conditions, was compared. PMID: 20600587
  12. The aim of this work was to study the effects on litter size of variants of the porcine genes RBP4, ESR1 and IGF2, currently used in genetic tests for different purposes. PMID: 20576168
  13. Promoter-specific expression differences of IGF2 isoforms and IGF2AS between biparental and parthenogenetic swine fetal tissues were documented. IGF2 and IGF2AS are paternally expressed. PMID: 19571260
  14. In both skeletal muscle and heart muscle growth, the insulin-like growth factor-2:myostatin interaction seems to play an important role. PMID: 19674865
  15. Effect of genotype on proteolytic enzyme in skeletal muscles during growth. PMID: 15560245
  16. Mutation controls the paternally expressed QTL for backfat thickness in a cross between Meishan and European Whites. PMID: 15678747
  17. A significant effect of linkage disequilibrium between IGF2-in3-G3072A and IGF2-in7-G162C on backfat thickness and lean meat content was found. PMID: 16706926
  18. Results showed that in IGF2 gene, the predominant allele was C, and the predominant genotype was CC. and that Wuzhishan pig breed was at Hardy-Weinberg equilibrium with respect to this SNP. PMID: 17284425
  19. The majority of IGF2 transcripts are expressed from promoters 2-4 and are imprinted. PMID: 18228173
  20. IGF2 gene has significant effects on individual birth weight and backfat thickness PMID: 18244923
  21. Haplotype variability around a known causative mutation in porcine gene IGF2, which increases lean content, is analysed. PMID: 18245828
  22. The results suggest that the expression of IGF2 and IGFBP3 mRNA in the adipose tissue of pigs exhibits specific developmental changes and different patterns between the two pig breeds. PMID: 18487150
  23. The current findings suggest that IGF-I and IGF-II have different effects on porcine adipose cell development. PMID: 18640238
  24. Methylation status of differentially methylated regions of Igf2/H19 locus in porcine gametes and preimplantation embryos are reported. PMID: 18983907
  25. The selection based on the IGF2 mutation in Poland may be very useful in Polish Landrace and Large White pigs, where the G allele is still relatively frequent. PMID: 19638682
