21 SNPs were identified, which affect the amino acid sequence, together with a 3 nucleotide deletion affecting amino acid residues 133 and 134, replacing K and A with a T residue and a 1-base deletion creating a premature stop codon, which would produce a truncated (presumably inactive) protein, as summarized in Figure 1.

The new study demonstrated how a broadly neutralizing HIV antibody called PG9 disarms the virus by grabbing hold of the sugar at residue 160, along with part of a second sugar and a short string of amino acid residues in the V1/V2 region of an HIV spike.
Osta's researchers discovered a key role of mid- and carboxyl regions of PTHrP on growth retardation and early senescence in mice created by inserting a premature termination codon TGA in the PTHrP gene corresponding to the codon encoding amino acid residue 85 of the mature protein and creating a "knock-in"(KI) mouse expressing truncated segment containing 1-84 residues of the mature form of the PTHrP protein.
