Heavy-chain variable-region sequence from an inulin-binding myeloma protein
Biochemistry.
.
Abstract
The entire variable-region sequence of the heavy chain from ABE-47N, a BALB/c inulin-binding myeloma protein, has been determined. This protein is unusual in that the third complementarity region (H3) is extremely short, consisting of at the most three and probably only one amino acid. A comparison of the heavy-chain hypervariable regions from mouse, human, and rabbit proteins shows that the variability in length of H3 is greater than that seen in the first or second hypervariable regions. This variability in H3 length suggests a specialized function for this region.
