31. Fusion proteins are very tissue-specific and mesotheliomas.32. The enzyme activity of the fusion protein is dependent on the proper folding of the ring domain. 33. Palivizumab targets the fusion protein of RSV, inhibiting its entry into the cell and thereby preventing infection. 34. The LF / EF binding site is now being utilized for delivery of therapeutics via fusion proteins . 35. The fusion proteins formed by these translocations lack the DNA-binding domain, causing the protein to lose function. 36. Nucleolin at the cell surface is the receptor for the Respiratory Syncytial Virus ( RSV ) fusion protein . 37. Tuesday Silber defended the school's Seragen investment, citing successful tests of the company's proposed drug, Interleukin-2 Fusion Protein . 38. The extension of cerebellar neurites on purified PTPkappa fusion proteins was demonstrated to require Grb2 and MEK1 activity. 39. To study this, one research group used a TALE-TET1 fusion protein to demethylate a single CpG methylation site. 40. The transpeptidase activity of sortase is taken advantage of by structural biologists to produce fusion proteins in vitro.
